What NOBODY is telling you about the WiiM AMP! - a marketing rant?

I feel like we have a tendency to overlook older equipment in the audio industry. I express my frustrations with the way audio equipment reviewers play the system of making a living on KZbin. I love the WiiM amp and all its functionality... but when do we say that it's not as good as something that's less than half the price. Just food for thought. This video is not meant to call anyone out or invalidate anyone's opinion about the WiiM amp. I own and appreciate what it does for the setup that it's in.

Fun fact, what you recommend is exactly what I switched away from. I got tired of having a gigantic receiver. I wanted something small that is good enough. And the WiiM amp is just that. Good enough for its size and price. And HDMI Arc, dude I haven’t even used the remote since I bought it.

[@CascadeAudio-ub6pg]

Then it’s perfect for what you need and that’s great! I kept mine and it’s in use at my parent’s house.

[@claudiabailey5302]

Telling someone to buy an old second-hand receiver instead isn't really good advice. I have a receiver and they are great but take up a lot of space. I would say that most people listen to music in a budget way and £299 fits most people. Does a receiver sound better of course it does. But this is a thing that plenty of people would be happy to have tucked away and connected to their TV. Whilst I get the argument that a receiver is better this easily offers up the way people listen to music and it is a step up from streaming on your phone or a little Bluetooth speaker. It's a thing that people would put in their office or in another small space in their home. The app has a lot of versatility and you are correct it's sleek and modern-looking which is actually a major selling point for people as well as the price. considering that Spotify is the most listened-to streaming service it is clear that a large majority of people are not fussed about the quality of streaming so much as the ease of how they can listen to something this fits the bill for a lot of people.

[@WorldWide3133]

Agreed on the use case being of the utmost. My Wiim Amps are in our home gym and for patio speakers. In both cases, it's installed completely out of sight, with nobody using the remote. Neither case are critical listening experiences, and my kids/wife can operate them without complexity. I have a full build out with separates for my Man Cave, which I really love. But, I'm not sure I even want that for my Den speaker setup, once I focus on that. Don't want kids and wife calling me because an input got switched..

[@Timoeltejano]

Thank you for your candid and experienced input. I have several listening stations in my house. I do use the Chi-fi amps for nearfield and desktop situations. I power my Bowers & Wilkins 607-S2 AE desktop speakers with an Aiyima A07 Max AND I have the WIIM mini attached to it as my DAC and it's great....for my desk. For my TV and main room listening pleasure I use an older Denon AVR2400 to power my Klipsch RP-6000F-II's as a 2.1 system which sounds amazing even when watching a movie. The speakers project like crazy. They're about 15 feet in front of me and I'll hear footsteps behind me. And none of my system is setup for Atmos. Just the combination of the AVR and Speakers in 2 Channel Mode are plenty. Also have a CD player hooked up to that. In my bedroom I have an Aiyima A07 Pro powering Polk Audio TSi-100s Which sounds spectacular in that small room application. In my Den I have a Sony STR-DH790 Receiver powering Jamo C93II speakers with an older bose sub and it sounds like magic. In my other office I have Sony STR-DH190 Powering KefQ150 speakers with an SVS sub and have that hooked up with a cd player and Fluance Turntable and enjoy the heck out of that. Everything has its place. Your review was balanced and fair. I liked it and now subscribed. Tim in Texas.

[@rosswarren436]

In my bedroom I have a "cheap" Yamaha RS202 Integrated amp pushing some vintage ADS speakers. I feed it using a WiiM Mini. Gives me great sound, options for plugging in analog sources, and even listening to FM if I want. Think I like my class AB system better than any class D amp, unless you go into the stratosphere on costs with PuriFi or ICE chips. Nothing wrong with those who want to get a WiiM Amp and call it a day, especially with its HDMI Arc connection, but I'm happy.

[@PFBzzz]

"...except for HMDI ARC..." Bingo. It's what makes the Wiim Amp a killer product. Perfect for adding 2.1 audio to a flat screen panel paired with a decent pair of passive speakers and a subwoofer, with the huge bonus of high quality streaming.

Yep. Optical is crappy for controlling volume on tvs. This is what it is. A nice little package without crappy looks and MacGyver like solutions.

Hey man, good stuff. I’m up on San Juan Island, neighbor. I was gonna add, if you have to have ARC, just get a slightly newer receiver or surround sound processor, whatever you want to call it. People practically give away their “old” amps from 5 years ago for the “new hotness” all the time. Thanks

[@cosmicheretic8129]

It's amazing what a decent older receiver is capable of with a good modern DAC and source. I would replace the Wiim mini with a Wiim Pro Plus using it's DAC or Wiim Pro to a budget DAC for much better sound.

[@CascadeAudio-ub6pg]

Great idea! I’d be interested to compare the external DAC of the WiiM pro to the internal DAC of the receiver as the receiver is only accepting 44.1khz from the WiiM Mini at the moment.

[@juangaxd]

Hey, really loved the video! Just one question: do you think that using an active subwoofer and applying a high pass filter at the amp level would make it work not as hard and therefore solve the power issues? Perhaps have you tried it? I really want to buy the Wiim and the only thing holding me back is what you mention, but I'm planning on running a 2.1 system so I'd like to know if that problem disappears when connecting a sub. Great content, thank you!

[@donnystrife1908]

I'm using the wiim amp with a big sub,highpass at 80hz and 93db speakers. It sounds really good until I get to about 80db. It starts getting shrill. The eq is awesome. You could always add an seperate amp later.

[@gtube314]

What you say is very close to my opinion. I purchased the WiiM Amp because I have some space constraints and it allows me to remove all the cable clutter, but when it comes to pure sound quality it is not as good as most of vintage devices. The WiiM Amp makes a lot of fatigue when it is called to control difficult and current demanding speakers. I think it is a nice device but only if judged feature-wise.

[@danielnorbutas8845]

Thank you so much for your video. It was super helpful and validating for me. I picked up a Denon receiver for $30, but got frustrated trying to set it up (I only want 2.1 audio and it is built for 5.1 or 7.1). So then I saw all the hype around the WiiM amp. I bought one thinking it would simplify my life and give me the ability to stream Spotify. I found the MiiM amp to not be powerful enough compared to the Denon. I thought I was crazy because everyone else loves it so much. Then I saw your video and felt like I wasn't crazy. So then I sent back the WiiM amp and bought the mini for streaming and it works perfectly. I get the connectivity of the mini and the power and rich sound of my Denon. Thank you!

[@jerryodom4542]

I wonder if you have any thoughts on how this might compare to my current setup. I've been using a chromecast to send audio into my Sony receiver from my phone (obviously using the HDMI on the Chromecast) and I think it sounds pretty great but I haven't really compared other options.

[@CascadeAudio-ub6pg]

I’ve heard really good stuff about the value of chrome cast for the money. I don’t have any personal in depth experiences with the Sony receivers. I’d guess you’re at a great starting spot. You MAY get better quality with a WiiM style streamer that could push more than 44.1k 16 bit but honestly I’m running 44.1 now and it sounds much better than the WiiM pro at whatever its default highest setting was. Pick up a WiiM and return it if you don’t like it I’d say.

[@GordonJones]

what this video fails to grasp is that the WiiM Amp solves for a specific scenario - that of a space-limited footprint. i have several old amps/receivers (and DACs) collecting dust and would LOVE to use them in my various rooms. the problem is that there's no space for those components in those rooms. mind you, these are not dedicated listening or home theater rooms, but rather a living, dining, and bedrooms. the WiiM Amp is a great product for that scenario and the fact that it includes as many bells and whistles as it does (does your receiver have an app?), in a single box and at that price point, is why it is remarkable. so, you can complain that it lacks the sonic qualities of your (legacy) receiver and you'd be (somewhat) right, but you've 100% missed the intended purpose of this product. in future "reviews" please compare tools that are meant for the same job - it needs to be a fair fight.

Really smart perspective and I 100% agree. If you actually care about sound, use a product that can meet your expectations. One caveat to going down to the opportunity store and buying a 15 year old receiver or amp to connect to your baby DAC might be the integration of an app to control your setup (lack there of). Those giant remotes suck and having to use multiple remotes is a deal killer for a lot of folks now. I'm admittedly lazy, so having a simplified interface for control and sound adjustments is important to me now that I've used them. But, for the price you paid, it's a strong trade-off/value proposition. Cheers!

[@Douglas_Blake_579]

The TPA3255 is a highly capable amplifier chip. You will find it in powered monitors, sound reinforcement, line amps, etc. You will also find it in high end audiophile and home theatre gear. It CAN deliver. But the point about the parts around the chip is right on target. Between inadequate power supplies, marginally rated parts in the output filters and poor design of phase splitters and input stages, many of the Chi-Amps are pretty marginal for sound quality. They will work well enough on an 8 ohm desktop speaker running at 10% power... but put them to work on a large room and nope, just not getting it done. There are exceptions, of course. For example: The Fosi TB10D after a modification to the heat sink and with an adequate power supply (36 volts, 10 amps) will definitely deliver. As will the original Aiyima A07 with the same supply. Like all things Chinese, getting the good stuff requires a bit of luck and searching.

[@impuls60]

The 3255 is designed for about 51V. How can I claim this?? because they TI have another model rated for 32V lol. Obviously the 3255 is the most capable on a 4ohm speaker with a 51V low esr psu driving it. The chip have low 2.nd harmonics and high dampening factor giving the impression of less bass. Those cheopo old amps have low dampening factor and high 2. and 3.rd order boosting the impression of bass sometimes.

[@Douglas_Blake_579]

@@impuls60 You are correct. The TPA3251 is rated for 36 volts. Having both chips on the bench here for testing I can tell you that harmonic distortion is almost undetectable below clipping. The damping factor isn't all that high, maybe 100 or so, because of the DC resistance of the output coils. (And cheapo coils will sabotage that rather badly, btw) In my bench testing, I find that the TPA3255, is happiest at about 36 to 40 volts. The TPA3251 seems happiest at 32 volts. This is a compromise between power output and temperature. Both are tiny chips with small thermal pads. They get right annoyingly hot at maximum voltages and require a very large heatsink and fan to sustain them. Yes, old school amps are a horse of a different colour... In class A/B amps with less capable supplies a very interesting phenomenon happens, power supply hum mixes with the signal providing artificial bass. You can test it with a simple experiment... Take almost any low-mid priced A/B amplifier and put one channel on a dummy load and one channel on a speaker ... now feed a near clipping level signal into the channel on the dummy load, with no signal to the channel on the speaker and listen to what you get from the speaker. You will likely hear an amplitude modulated 120hz hum from the speaker. This hum is caused by the reservoir caps draining and rectifier hum getting onto the power supply rails. In normal use, it actually happens in both channels. Of course some of the older A/B amps also have a slight nose up in bass to compensate for vintage speakers that roll off at about 100hz. Modern speakers can often get well below that, producing exaggerated bass.

[@slofty]

The funny thing is ALL of the people that make, engineer, produce, and master nearly all of the music you listen to would NOT be able to tell the difference between a small pair of KEF Meta's driven via a TI3255-wielding WiiM vs. the same pair driven by the house's long-loved Benchmark amp at control room level (80-85dB or so depending on transients) in a smallish treated room. The differences simply are not audible at that level-- we've tested it repeatedly with a variety of equipment, and yes, there were plenty of young ears present in the trials. If no audio engineer can hear a difference at identical levels-- sure, the Benchmark can get way louder-- then what's the point? Are you guys hearing 'secrets' in our work that we don't even know we put in there? I never understand these claims of super ears when no one in the industry making the stuff (whether good or bad work) that gets played thinks it is even applicable. This includes seasoned engineers that have NEVER had their work sent back by any client, whether for film/TV/music/etc. Where are the audiophile studio engineers?

The Dac in the old Onkyo is probably a Burr Brown and is going to sound as good as the Pro+ Dac. Dacs have come a long way since the 80s but not since the early 2000s.

[@coguglielmi]

The WiiM pro plus - w/o the amp section - is of amazing value, though when hooked to a proper amp. Parasound Halo Integrated in my case, with loads of power and extensive bass management, plus tone control if that's your thing when a given recording requires it. Though the WiiM integrated equaliser, DSP and DAC clearly deliver a better result than the amp's simple tone control. My Dynaudio speakers sing pretty well now! Much better than with the integrated parasound DAC or the Schiit I was using previously out of an obsolete streamer (Logitech squeezebox duet). Now you're basically advocating to decouple the digital streaming from the amp. I agree. Though you assume the WiiM mini will cut it, but when you hookup the mini vs the pro or pro plus to an amp's digital input (keeping the same digital chain including the DAC), there is a very audible difference. The included streamer makes the difference. My recommendation is: - need a specific amp + DAC -> WiiM pro linked to your amp with its internal DAC, using the digital S/PDIF connection - have listened to the WiiM pro plus excellent built-in DAC -> WiiM pro plus using RCA out to the amp's analog input, for just doing amplification - want a simple system with speakers that aren't too demanding, like > 80% of the market -> try the WiiM amp, it may work for you and it looks great with a form factor that's easily acceptable

Interesting viewpoint and yeh, my experience is my iPad feeding Apple Music into an old NAD DAC, into a 1990’s Rotel power amp is that it is more able to drive my 1980’s Monitor Audio M852MD’s than a NAD M10 integrated and sounds much better above 70db. Though, if I add a good Power Amp, an old Peachtree NOVA220 to the M10, no contest. The WiiM amp is really a $150 add on to the WiiM Pro Plus and as such is not going to do anything good and it doesn’t surprise me that your Receiver sounds better. I think many other reviews also saying it’s puny and not that capable in driving loads. All of this is a lesson in ensuring that we step back and look relatively at what things do. Most won’t notice. The NADM10 I bought was disappointing given reviews and I think NAD even felt so as they upgraded the amp section less than a year in. Old is not always bad. The Rotel Power amp I have is Class AB and rated at 50 W. It’s clean and seems to have lots of headroom. More so than the 100W NAD M10 but not even close to the Peachtree .

Dude, you've got only one video on your channel. You've literally found the golden formula to get viral videos: talk about what people are looking for 😄 I like the way you phrase things. Kind, honest and simply to the point. I especially like the final statement: people buy the WiiM at (admittedly) a great price, it's like a bargain. However, when you're in need to push the speakers more because of a larger room/space I think the WiiM simply cannot handle it. Full disclaimer: I haven't heard it yet, so I can't speak, but the fact that it's a tiny box like that simply comes with physical limits. Likely, at low listening levels it's fantastic, and the best value compared to many amps many times more expensive. But if you're going to listen for longer periods to higher volumes, this thing will not only be incapable of keeping up as you described, but it's also going to become defective *very quickly* without any doubt. It's still a recent release, so I'm sure we'll be seeing people frying the WiiM in the coming months/years. Great video, keep it up!!

This video is against the tides. Since 2019, I see reviewers worship these TPA3255 amps with measurements to back it up. So far, only Andrew Robinson gave truly negative feedback on these TPA3255 amps. Once with an Aiyima A08 Pro, and recently with the Wiim amp.

Great video. Finally someone not selling stuff. I have an old onkyo 7.1 receiver but it seems like it’s missing some notes when I use two speakers. Like the dialog is less. Tried all the settings. Does anyone recommend any hacks to use a 7.1 receiver with only 2 speakers?

[@sonusancti]

Your opinion is a breath of fresh air. Thanks. To think that Onkyo hasn't been upgraded with better filter caps!

[@CascadeAudio-ub6pg]

That would be a fun project but would be a lot of work and time that I don’t have at the moment

[@davidgriffin79]

You only need to upgrade the filter's if there's obvious voltage ripple, i.e. you can hear a buzz through the speakers; even then it may be that the buzz will go away as the caps re-form. Otherwise, yes the filters may need replacing. One of my hobbies is restoring old analogue (and some digital) hi-fi. The caps that need replacing are usually those situated next to regulators, and have started to dry out due to heat conduction from the regulator, through it's legs, into the PCB track and into the cap; also radiated heat will dry a cap out as well. Electrolytic capacitors have a finite life span which is a function of temperature and operating voltage. If an an electrolytic cap is constantly exposed to elevated temperatures it will start to dry out and it's internal equivalent series resistance (ESR) will start to rise. As ESR rises the I^R power dissipation will increase causing the capacitor itself to get hot; this in turn will accelerate the drying out process.

[@sonusancti]

@@davidgriffin79 Even if the filter caps have not gone bad, inferior caps replaced with superior caps make a clear audible improvement. Don't need to wait for stock caps to go bad. This in of itself is one of many rabbit holes in audio I'm in.

[@davidgriffin79]

@@sonusancti You have to be careful here. Power supply capacitors, i.e. those _not_ in the audio path, do not in any way, shape or form affect the sound quality; they bridge the power rails and their job is to simply remove voltage ripple and provide a limited reserve for transients, as far as power supplies are concerned there is no such thing as "Audio Grade" - this is a misnomer propagated by the self-appointed "audio gurus" who have zero understanding of electronic engineering and jumped upon by certain manufacturers to inflate their prices. Now, for electrolytic capacitors _in_ the audio path, that's a whole different story.

I'm only changing filter caps ok? And I've heard the differences for myself and yes they can be called audio grade because of their sonic improvements from experience.

Wiim is doing some nice things, gradually. Would be nice to have this amp in a dual mono design to double the power and add a nice linear power supply, ability to swap OP-AMPS and now it's a solid system.

[@IvanITpro]

I own one and mostly for the HMDI ARC input for my TV bedroom setup with some Micca RB-42s speakers and a small sub. Its form factor is perfect for bedroom setups. No DAC/amp combo has had this feature working well for me for anything below $300 (SMSL AO300 i.e.). I will be modifying WiiM’s 2 dual channel $1 opamps to Sparkos Labs SS3602 - $80 opamps, as the output stage is very important to be done properly with discrete components and can not be achievable with great sound quality from $1 cheap integrated circuit opamps. Hence Fossi Audio and Aiyima have amps that allow opamp rolling and use the same TI 3255 amp chip, but the sound is night and day when I replace the opamps to Sparkos. I will upload a video of the mod to YT in March. I will let you know in here. Or just subscribe 😅

[@presterjohn71]

I've literally done the opposite of you. I had a mini coupled to a vintage system but have now swapped to the Wiim Amp. The difference in quality is minimal to my ears but it looks so much better in the room. Neatness does have a value.

[@kymvalleygardensdesign5350]

Thank you for your honesty here I keep thinking WIIM amp but the fact it struggles to push 60 watts and distorts under load kind of worries me a good second-hand amp and the WIIM streamer option have been something I have also been weighing up. .

[@donpatisson]

You are 100% correct and I just made the pricey experience. My 17 year old NAD C325BEE amp had an issue with the right channel and needs repair. Instead of streaming music to the digital output of an old Apple TV or Chromecast audio in my amazing ARCAM rDAC, I bought the NAD C700. I have floor standing speakers from PMC (17 years old…) and the C700 does a fair job but is far from the warmth and certain details the old C325BEE is able to deliver. The bass is less precise but more present (the DAC is a reason), but it powers the speakers better (and delivers more power at less volume compared to the new C700). Spot on!

[@hgodfrey]

I totally agree. I have a WiiM mini going into a Cambridge Axr85 which I bought used. Total cost was £200. It sounds great.

[@trudimcleod5042]

Great video and very honest! The thing about theTPA3255 chip is that it is very dependent on the quality of the switching power supply upstream from it, which is internal to the WiiM amp. Also the op-amps after the chip matter a lot, and they are not swappable.

For average joe that is stepping up from listening to a little speaker then yes it’s a killer.

[@Audiomainia2310]

Absolutely correct. The Wiim amp can't handle dynamic loads / even with easy to power Klipsch speakers. That's what you can expect from a cheap class D amp - period. A much better alternative in my opinion is the Dayton Audio VTA 200. 100 WPC, sub out, class A/B amp, tube pre amp, very cool looking retro VU meters for $349.00 - worth the $50.00 upgrade over a Wiim class D any day of the week.

The Mini and receiver are missing Base Management and the equalizer.

[@CascadeAudio-ub6pg]

The WiiM Mini has a 10 band graphic EQ and a 4 Band parametric EQ. While the WiiM does not have bass management. Most receivers can be set so that the front channels are “small” speakers and the crossover to the subwoofer can be set at 60,80,100hz. I set mine at 80hz (the THX standard) and that removes everything below 80 from my main speakers while pushing everything below to the sub. So in short, you get two EQ options (WiiM and receiver) and the receiver handles the bass management.

I have a 2-channel Onkyo amp with a Wiim mini in my garage powering my old bookshelf speakers hanging from the pegboard wall, and I proudly left the $25 Goodwill sticker on the amp. Even if your budget setup sounds better than anyone’s new $500 soundbar, you’ve got to stay humble…

[@mrboat580]

They are typically right in the realm of getting what you pay for. These products typically have very low noise. I buy used AVRs because of the bass management, with many being over 100wpc rms/8Ohms. All these import products rate their spec into 4Ohms which is misleading and more comparable to car audio. They are basically 50 wpc amps at best, which has always been entry level power for all but the most sensitive speakers. Most people that are used to loud music will push these to their limits. I have the Fosi BT 30D pro in a bedroom for lower level listening. I also have the V3 with a 48V power supply and it's adequate but nothing like the 40# Denon AVR from the early 2000s.

[@thorenjohn]

Excellent commentary and presentation. Thank you!

[@alanross99]

You are 100% on point with this. Any name brand receiver from ANY time period is going to sound better than these chip amps. There are HUGE bargains on old AV receivers that don't support the latest video specs, but the audio is fine. I've seen Pioneer Elite receivers with over 100 watts per channel going for less than $100, just because they don't have HDMI ports, etc. And don't worry about the DAC in the receiver, or even if it has one. Pickup a Wii Pro Plus instead of the mini and use RCA's to connect to the receiver. Want a better DAC than that, then get a Wiim Pro (not the plus) and go pickup a DAC from SMSL, or one of the other DAC companies. Heck, I bought a Wiim Pro Plus to fee by vintage silver Pioneer gear, and then decided to get an SMSL DAC to see if I could get something better than the one in the Wiim Pro. It doesn't make sense to worry about tiny differences between DAC's to then just suffer with one of these chip amps that don't even have a full set of specs. Sure it's 60 Watts, over what frequency range, and at what level of distortion. These old receivers will quote you over 100 watts, 20-20Khz with well under 0.5% distortion. Now THAT is hifi sound.

[@andrewskaterrr]

"Any name brand receiver from ANY time period is going to sound better than these chip amps" Just an FYI, not every AVR from a name brand was good. You're making a poor assumption there. These chip amps are objectively good, but if you go above it's output limit, you're going to have issues just like you would with an AB amp. See Erin's Audio Corner's measurements of this thing. Buying a tiny all in one desktop device and expecting big wattage numbers is comically naïve. "These old receivers will quote you over 100 watts, 20-20Khz with well under 0.5% distortion" As you should know, manufacture claims and actual performance are two different things, sometime drastically so.

Thanks for commenting. As I understand it… the coaxial output would be a full range stereo output. It does this by sending a digital signal over RCA to another coaxial device. This would not work with your SVS as it’s expecting an analog signal. The only way to get a sub out would be to connect to a device that has bass management. Hope this helps!

After a few days of demoing the WIIM I had to return it...and FAST! It is not only its severe lack of dynamic headroom, but also that it just doesn't sound good at all. Sterile, bright, no pace and rhythm, mechanical, even grainy on top. The upper mids and lower treble are unlistenable - at least in my home office system (Wharfedale Diamond 12.3 and Velodyne sub). If it had pre-outs it would be terrific, as I would have kept it and hooked a good amp to it. Great honest review!

[@spacejaime]

I forgot to mention inner detail, or lack of it, and soundstage. Soundstage is quite limited, but if you crank it up, it collapses. Harsh words, but lets be realistic - this is a full all-in-one amp looking for a speaker to match (good luck), and users that want background music.

[@CascadeAudio-ub6pg]

Thanks for the kind words. My experience in the mids were okay. The top end seemed a little more “bright” and “shrill” than other amps. I did bring down the 1.5 db high frequency pad on my Tannoys when using it.

I've bought a Wiim Mini last week, with my Yamaha receiver and Cambridge Audio speakers it sounds really good.

[@n.o.b.s.8458]

There's a lot of merit to what you're saying here. I agree that this isn't a bad product, but rather not what it's being made out to be. Without putting down the WiiM amp at all, it's basically an average $100 amp with a lot of extra features. It is a unique product, it's a great way to reduce clutter and get good sound in a more elegant package. But, the tradeoff is you can get better sound for a lot cheaper. I also love that you brought up the amps ability to drive at variable loads. To dramatically oversimplify some technical information, impedance drastically varies throughout a given speaker's frequency response. It tends to peak around the bass region in speakers, and also somewhere around the upper frequency range (where it peaks can vary dramatically). All this to say a cheaper amp MAY sound okay, but will likely have less clearly defined bass. I've listened to plenty of cheap amps and some are fine, but it's worth getting something solid that you can trust. As a replacement for the WiiM amp, I'd really recommend taking a look at the Fosi Audio V3. I am NOT an amp guru, but the technical measurements sold me on it and I've been very happy with its performance. With an upgraded power supply it can even drive a lot of speakers to downright painful volumes. Paired with a WiiM mini it would make a great system for under $200.

[@walterdockins8475]

I'm guessing this video is for those not familiar with audio. Those that have been into this hobby for even a short while already know that one can get older used pre HDMI class a/b receivers for dirt cheap, even the flagship models. However, those that want something small and unobtrusive for a desktop system, or to blend with room decor might opt for one of the chip amp products. I actually picked up one for my desk, it's a rare Cabasse Stream Amp 100. These retailed for ~ $600 however a guy on Craigslist was selling one new in box for $115 years ago. I have it connected to a set of Boston Acoustics VS 240 speakers and two Mirage Omni S8 subwoofers. Great sound for a desk rig! I also jave a WiiM Pro streamer in my main system in the family room.

[@dylanemeraldgrey]

Funny coincidence. I received the wiim amp for free. I switched it with my very old onkyo tx SR305. I tried it with some vintage new large advents and also with my HECO Celan Revolution 3's. It would take too long to go into a whole review, but one of the biggest cons was the lack of power - also felt like the dac should have been a little better, which may also speak to your concerns. My streamer for the onkyo system is just a laptop. I also have the laptop connected to my TV via HDMI, so it does it all, plus surround sound. It's not the best, and it's not the latest and greatest, but it does beat the wiim amp on sound and mostly matches the functionality.

[@dubc4179]

Onkyo Amps/Receivers are constantly underestimated. I recently tried out about 5 or 6 Amps including ones from Sony, Wiim, Fosi, and Yahama. I ended up with the Onkyo 8260 Stereo Reciever for $249 on sale and I love it's sound. It does a great job pushing my Elac Uni-Fi's and has a pretty good built in DAC.

[@gurratell7326]

What you do hear is probably the fact that this amp is load dependant, so the frequency response will change depending on the impedance curve of your speakers. Though afaik it's not really that much more than +/-1dB, so audible but not that bad. The Wiim Amp do have a PEQ though that you can use to combat some of those frequency variations.

Power consumption is something I am taking much more notice of these days, I have an attic with a stack of AR receivers, now replaced with soundbars

The only reason I'm even in the market is that I was thinking of either leaving the Onkyo with my ex or getting her a simple replacement.

[@JungYT]

I almost bought a WiiM amp, but stopped because it doesn't have a USB DAC, and I use my PC USB for music. I ended up buying a Dayton Audio HTA200 because it has the inputs I need and the power (A/B amplification). It also has a tube preamp, VU meters and big toroidal transformers. I have it hooked up to some small Klipsch bookshelves and it sounds nice. I have some larger 3-way speakers (Hivi-Swan DIY 3.1A) I am building that I will eventually hook up to it. I have a feeling its going to sound awesome. I have an aversion to using a big clunky receiver, even though they can be had for cheap.

[@edperkins5532]

The WiiM amp does has load dependency issues, but all TPA3255 amps without Post Filter Feedback (PFFB) have the same problem. Erin points this out in his review too. Your Tannoys happen to have a very complex load (6 ohms to almost 60 ohms @ 2.5 KHz) which exacerbates the problem. Perhaps WiiM will come out with a WiiM Pro Amp version with PFFB.

Your review or quote, "2 cents worth" was, enlightening, and I have only one observation I would like to submit: The Wiim amp and Wiim Pro Plus both with an AK 'Velvet Sound' chip sound much better at low volumes than my Yamaha amplifier bought 10-12 years ago. I suspect because I do not yet have a DAC in my original set up. I switched and ran the Wiim Pro Plus through the Yamaha, and I found that, at least, to my Amateur Audiophile ears, there is no distinguishable difference between the two except perhaps that at extremely high volume, the Wiim amp lags behind the Yamaha in terms of heaviness, depth, or gravitas, if you will. The price point is what I am the most happy about, and your candor has persuaded me to subscribe to your KZbin channel.
