[@lexicon612]

Coffee?

[@JimRussell-ir9ue]

I got a pair of these amps. With the sparkos op amps, the sound is incredible. Best little setup I could hope for. I paired them with the Aiyima T8 and am very satisfied. Thank you, Cheapaudioman, for the great videos reviewing cheap components.

[@geoffreyduckworth6062]

OK maybe you can answer what everyone else who reviews two bridged A07 Max amps (one for each speaker) avoids. Done that and it works fine but how do I connect my single active subwoofer? The aux out on each amp is stereo so if I use only one of the aux outs (from left or right amp) I will get bass from only one channel and there will be bass on the other channel also that won't be sent to the sub. Most of the 3.5mm 2 male jacks to 1 female are for phones so one male is for the speaker and the other for the microphone so they don't work (I tried) and in any case I have read that using a simple splitter (2 male stereo to 1 female stereo) is not a good idea as at best it reduces the overall volume and may cause damage. My sub has speaker level inputs, which I would prefer to use, but when I connect the sub cable to the same bananas as the main speakers (8 ohm) , the amps don't work, why is that when the speaker level inputs on the sub are 1k ohm so that should make minimal difference to the total impedance and certainly not below 4 ohm which the amps are rated for? So my question is once I have the A07 max in mono mode and one is driving the left and the other the right speaker, how do I connect my single subwoofer (Wharfedale Powercube 10+ which has L and R RCA connectors and L and R speaker level connectors)? Oh by the way the sub is also used for my AVR and when I use a one RCA to two RCA adapter on the left sub RCA, with both A07 max and AVR connected the volume on that channel is very much reduced. I've already made a switching box so the main speakers can be used with either AVR (best for movies) or A07 Maxs (best for music). Previously I used a single Arcam Alpha 2 amp instead of the two A07 Maxs and had no problem at all, as the Arcam worked perfectly with cables also running to the sub speaker level inputs. Apart from the amps the set-up was the same and worked perfectly.

[@aniketnraut]

Can i use these in Mono mode and get two of them to power my Elac F5's. On paper they are on par Emotiva BaseX amp.

[@danapuopolo8397]

I am running a pair of these in mono with 48 volt power supplies into my Emotiva B1+ speakers with a 12 inch Monoprice subwoofer. Source is a WiiM Pro Plus with the AKM DAC. It sounds amazing. With some songs I can close my eyes and the speakers disappear. Dynamics are great too. This is more than a glimpse into high end audio. EDIT: I put LM4562 opamps in place of the NE5532s. They sound a lot smoother and more accurate.

[@kenteo24]

Did you compare using one vs using two? I am running on one right now and the sound is already as amazing as I can imagine, given my preamp and speakers, so I am wondering if I should take a leap and bi-amp.

[@100bsl]

Hi... how did you connect the subwoofer?

[@1324390]

I have the original A07 and the Max, both bought at Randy's recommendation. The Max is housed in a much smaller case than the original. As a result when fed with a 48V power supply the Max runs much warmer than the original, despite the addition of side and bottom vents. Even with no input signal the Max gets quite hot when left on. I just wonder if this would affect its operational liability in the long run. The disappearance of the on/off toggle switch is also regrettable.

[@greatpix]

Here's a trick I learned from a guitar forum for getting knobs off. Take two spoons and place them on opposite sides of the knob, with the curved part down. Then gently push down with equal pressure on both sides and the knob should come off.

[@stevezeidman7224]

Loved the intro, Randy! I love seeing the little people. Typical fun ride on this vid.

[@WireHedd]

Laughed my ass off at the tool segment and disassembly. I used to make videos for a company doing electronic repairs on circuit boards, PCs and mobile phones and the tools were always different or proprietary and sometimes finding the right one was actually part of the video and repair processes I had to demo. Answer? Small powered screwdriver with multiple microbits. Just made me smile so thanks Randy. Also liked the amp. LOL

[@iikatinggangsengii2471]

it was dizziest synergy ive heard

[@Music-Tech-Life]

Love your attitude and your channel. I'm a 67 year old musician. Music is my thing. But I'm a bit of a geek also. Macs, Logic X Pro, etc. You get it! It's all-out the sound and what your very personal ears here. Some people don't have good ears and can't hear the difference. But some of us can and we listen closely. I have all old school audio equipment. Large Advents, Kenwood KA3500, Stanton Turntable and a great record & CD collection.

[@adsph]

Hi Randy. Finally an amp with bridging. Could be a game changer for some. Well done.

[@IvanITpro]

I got the AIYIMA 07 MAX over a month ago and put Sparkos opamps in it. It sounds beautiful as a stock amp but with Sparkos it’s on another level. Just doubles/triples the sound quality (stage, width, depth, dynamics, bass - everything!) Plugged in my Schiit Mani 2 clean/sterile phono stage and vinyl records and playback from the past now sound like it was remastered in my listening space with AIYIMA and Sparkos! It’s like I upgraded to $3000 phono stage yet it’s just an amp with Sparkos magic in it! Very impressive and very good in the low end! Also I’m just using the stock PSU as the upgraded 48v 5A GaN PSU resulted in poor bass response and less dynamics, so I returned it the same day. Maybe the non GaN PSU is the way to go with these… just FYI 😉

[@frankplissken143]

Oh no! That is bad news for sure, I hoped the Gan would be cleaner as I've been impressed with my gan phone chargers being so much cooler and smaller than conventional ones.

[@justicewayfarer]

thanks for the info. what Sparkos opamps did you used? thx

[@r423sdex]

Another level !

[@denis4072]

Are you sure it isn't the stage of mind?

[@lyletaylor3728]

Your daughter is adorable. It was nice to see her help with the intro. :) Thanks for the good video.

[@bertpeters1866]

Randy, anyone that's leaving your channel is nuts. Maybe they think you crossed over to the dark side lately with your visit to New York. Anyway, you have given me hope! The tool segment was just funny. Your navy reference reminded me of what Air Force mechanics used to say: If it doesn't work, get a bigger hammer. Keep up the good work, and Merry Christmas!

[@josexavierjr.5633]

Great video, Randy, as usual. The bridging feature is cool for sure…..👍

[@jsherman999]

Very interesting insight into these two companies, thanks. Really want to get more takes on running these as monoblocks.

[@RUMBLEGO1]

I was in Ron's LIVE chat last night and i mentioned the V3 and if he had ever heard it. He said "Is that the amp that Randy like's so much". I assumed it was and said yes. I would love to hear what one of these little amazing amps would sound on an efficient speaker like those Saphire's that Ron has. Especially that new Caladan speaker that he is raving about. I bet it would sound amazing and would like to see the look on Ron's face as i know he uses fairly expensive gear. I use my V3 on very large Mirage OM9 omnidirectional floorstanders in my living room. They were listed at $1300 back in 2001 and still sound amazing. That little amp sounds incredible with them! Stunned, and it actually sounds better the more i turn it up! I give out before it does as far as how loud i prefer to listen. Just wanted to share that with you Randy!

[@RUMBLEGO1]

I have the early A07 as well and just tried the V3 on a whim thinking I would probably send it back. NOPE! So this new one is now the V3. Curious if the newer Fosi will possibly sound better than the V3? time will tell I guess. I won't be the first to jump in I know that. Satisfied with the V3. Definitely a cut above the older A07.

[@RUMBLEGO1]

These little inexpensive amps are not just for inexpensive bookshelf speakers. People should try them with some of their nicer speakers and just check it out! Totally surprised at how good it sounds. Totally stupid for under $100. All of us for the win!!!

[@tmdillon1969]

I have a pair of Mirage 490i I bought for my little apartment back in 96. I just saw a pair of the OM-5s for only $500 yesterday. Mirage is the best value on the secondhand market right now. The good Canadian stuff is getting lumped in with the garbage that Klipsch was selling as Mirage in Best Buy in the 2000s. I've seen M5s for $300 and 1090i for $250 in excellent condition.

[@collije]

Lol love the use of vice grips 😅

[@MrAzeker]

Thanks for doing these thought experiments out loud and in the flesh. You say this will likely be your end game desktop setup. For myself, I'm using Edifier S2000mkiiis and I love them. You've said that you don't like powered speakers, but for the cleanliness of setup (wires) and the quality of current $200-400 powered bookshelves, what's the advantage of having everything separate? The streamer I can see being useful if you don't have Spotify. But if you do, you can control through your phone easily. But as you're likely sitting at the computer, that seems unnecessary. I have a pair of Sony SSCS5s bought through your affiliate link (thanks), and I prefer the S2000. Though they do sound great in our little restaurant in Korea. Similar price all in and one optical to the computer for setup. Looking forward to your A7 vs V3 review.

[@6StringPassion.]

I know I am an audiophile precisely because I get annoyed by audiophiles.

[@chinmeysway]

example? just wanted to have a who gets most annoyed type thumb war w someone on it..

[@MechAdv]

The new Fosi amp corrects my one complaint with the V3, which is that it doesn’t have a volume controlled line out for a subwoofer. The mono block feature is nice too, although I’m not sure that switching it to mono block mode allows you to bridge the outputs or if it bypasses the volume control like a Power amp should. This and doesn’t have the sub out, so it’s a pass from me.

[@jayweb702]

I have an Aiyima DAC and I absolutely love it! This amp might be next.

[@riccitone]

Oh man…how are you so informative AND entertaining at the same time? 😂❤

[@WardoUSA]

I think these types of amps are super cool. If my kids actually wanted a system I would start here without a doubt. I put a budget vinyl system together for fun, it’s powered by a rockville blue tube hybrid amp. Not a true tube preamp, but wow does it work great.

[@CinemaDemocratica]

I got an SMSL AO300 a couple of weeks ago and we're just waiting on a pair of Dali Spektor2's to arrive here from a private seller in the UK. Really looking forward to it.

[@cylisblack4758]

Wish these mini amps would come with a true pre-out. Bought the v3 which says it has a pre-out but its not. Just a fixed output, no volume control. The company that comes out with that this feature is gonna make some $. A true mini mono block would be nice as well.

[@Kratos41277]

I have that ratcheting screwdriver set too. Super handy!

[@jacktough]

Can really feel your enthusiasm with this one 👍

[@SpirallingOut]

Can't wait for the mono performance comparison video between two of these and a couple of Fosi ZA3's.

[@vwmountainman9701]

[@cheapaudioman]

Why thank you, my friend

[@johnnyflamini8456]

The intro was so awesome I had to go back and watch again 😂

[@csimet]

I needed a separate 2-channel amp to power the last two channels of my 7.2.4 AVR and was looking at the Fosi V3 and this Aiyima A07, but... and this is huge for me... the power/volume knob. The power switch needs to be separate from the volume setting so you don't have to fiddle with the level setting every time you power it on/off. I need to look elsewhere... or perhaps add my own separate power toggle. For amps under $100, they are throwaway anyway so I just may.

[@rakitakhan]

I just ordered one. It won't get here until the 1st week of Feb 2024. Oh well. Thx for the video and info. I currently have a QSC GX5 amp on my desk driving my Delcoid LM - 1 setup. I'm hoping this little amp will be able to push my sub enough to satisfy me. The QSC has 500wpc so I'm not expecting it to be a direct replacement. I just need the Aiyima to get me thru for a bit. I'll let you know how well it works with a bigger speaker setup.

[@jonviolet6116]

Gets really hot on 48v . Sounds fantastic though in bridged mono mode. All that power for £110 for 2 brilliant 👍

[@rahulsankpal9928]

Is Fosi V3 better than A07 max if we do not consider mono mode?

[@MindfulProgramming]

It's a nice amp, but I'm waiting for the Fosi ZA3 because I really, *REALLY* want the 12v trigger to connect with my WiiM Pro's. BTW what speaker/amp switcher do you use/recommend?

[@thespotlightkid1011]

I fancy the mono capable Ayima. Tho if i bought two, i'd always remember how half the Class A & A/B amps i.m.exp & reviewer's, could sometimes sound inferiour in their bridge mode, esp if you hsve sensitive speak's & don't need anywhere near the extra watts, but Class D is another ball-game & i couldnt resist trying 2 if i liked 1.

[@ML-rm3vk]

Brillant video and thank you for your humor very funny.

[@2madamimadam290]

Don't have the 'max' but the old AO7 is great. Love 'em for surround and center channel amps. Total bargain.

[@iikatinggangsengii2471]

well yeah align with the expected cost

[@PhilipBallGarry]

Excellent review as always Randy. I have two music sources, a Pi Streamer and a CD player. Which budget class D amp would you recommend with more than one RCA input? Cheers!

[@JohnJablonski]

Great work on the graphics for your intro sequence

[@mcjonner]

Wonder if that would be good for a diy sub if you run dirac to manage the eq settings I just seen a video where the guy made large jtr clone speakers with a huge 18 or 21" sub for super cheap and used a cheap 2.1 Chinese amp and he said it was very impressive. I wonder if I may try this actually, those are some cheap watts and build a ported 15" and use dirac to eq.

[@leetaylor13]

I bought a pair of A07 Max amps with 48V, 5A PSU's to replace the plate amps in a pair of 15 year old subs that use 200W Peerless XXLS 4 ohm drivers. The power transformers in the current class AB plate amps are mechanically hummy and drive me nuts on quiet passages. I still need to buy and fit banana terminals and bypass the current plate amps. l have a Minidsp SHD Studio and a Minidsp DA8 for pre amp, Dirac, crossover and DAC duties.

[@AllHandlesHaveBeenTaken]

For your upcoming comparison with the Fosi V3, I want to request more detail about the aux port functionality of the A07 MAX. Thank you

[@erichudson3307]

So if im running the A07 max in mono and I want to upgrade the op amps like a sparkos ss3602 would i only need to purchase 2 chips? One for each of the left signals since mono is only using one channel in each amp?

Hi Randy. Will this one give more bass than the V3? I found the V3 a bit dry with Elac DBR62 and a SU-1

Looking forward to your impressions of the ZA3, especially setup balanced with the JNOG2. Preamp suggestions there??

[@NeilBlanchard]

Nichicon caps are very good quality, and those have a max voltage of 63V - which means there should be no issues with a 48V power supply. And there appears to be room for Sparkos SS3602 op-amps. The lack of a sub-out is a bit of a miss, though.

[@IvanITpro]

Yup, already have Sparkos in mine, doubles/triples the already amazing sound quality 😉 No BS! Sounds better without a sub in my system 😁

[@larrygaines7462]

These mean well type switching power supplies have a adjustable voltage veneer on board ,next to green on light. I turned my 36v to 40v ,no danger, yep ,do the math, it raised the power of the monoblocks significantly. I only add good tips. Thanks Randy for letting me contribute. I'm too old and sick to start a channel.

i m just getting so exited about audio gear with those again. i m just a budget person. i like good audio, but i m not willing to pay hundreds or thousands on an amp just to maybe get from 90 to a 95 in quality. All of that Fosi and Aiyima Stuff is just so exiting because its NEW decent audio gear, i can actually afford and it also means its finally time for me to say goodbye to old used avrs and stuff like that and it feels awesome. With chip shortages and also buying used gear becoming more and more a gamble because it gets older and older and more rare, something about: just going to amazon and buying it because its available feels so relaxing.

[@bling5279]

Would love a comparison vs the Fosi ZA3. Also, If I already use Sparkos OpAmps on my J2. Is it overkill to use the same OpAmps on the amp too?

[@ADREISTER]

Sparkos upgrade will just add another layer and inherent character. THD is always compounding and every component your music travels through, will "effect" the end result. Can you hear it?🤷🏼‍♂️

[@PhillioDoede]

Its good to see improvements and I know its culturally how these companies work but I think these constant flow of essentially the same thing is very confusing for the average consumer looking at all these amps. Its also super frustrating to see another amp with a aux output instead of pre-amp out, what exactly is the point of the aux? I'm sure we'll see more of these 3255 based amps so I'd like to see one of these companies make a real power amp; no volume control or any other features and release that with a real companion pre-amp with 2-4 inputs, remote, maybe a good DAC and a dedicated subwoofer output, aka a baby version of a Schiit Saga and Vidar.

Great reviews and humor

You are the best man on KZbin audio

[@MrTonycarpets]

Hi randy, excellent review as always, I'm wanting to see the a07 max in Bridgend mode as I've bought one and would want to try it. Pictures please pal👍

[@rickbrookes9491]

KZbin viewers are fickle…but I, by nature am pretty lazy… and I like to stay subscribed, even if at times I don’t agree with a video. Sometimes, a video comes along that I enjoy and I don’t want change, so… I stay subscribed! I like you Randy… keep it up, and I’ll just continue to watch for the consistency and… entertainment!

[@stevenconnectingtogether6703]

Hi Randy, How this compare to Sabaj a20a in term of sound quality please ? I have 2x Sabaj at bridge mode 😅

[@superintertainment11]

I am new to HiFi so don’t roast me, I’m running a pair of Elac uni-fi run off a aiyima t9 and I really like just running it off Bluetooth. I am wondering if I would be better running something like the A07 or v3 off of a SMSL SU1 or am just fine with the T9. I am in an apt so can’t turn them up high anyway so volume is not an issue with the T9.

[@Eron55555]

UB52s? I can tell you that 2x A07 Max's KICK on UB52s.. WAY better than T9.

[@asan1050]

ThanksMuch!

[@francescotenti193]

Glad to see you going back to "your roots" and taking those Sony's out of retirement. One comment though, your videos have become a bit too dark, any chance to make them a little brighter? Thank you and Merry Christmas!

I attached (2) Sparkos 3602 Ops to my $50 headphones with electrical tape. Sounds like a $3000 set of cans now! Just have Andrew build us a receiver with all of his magic "schiit" inside! It's going to cost less in the end...and only one box.

[@ericaudio]

Randy , we like your personality!

[@MrSabiso]

Just curious. Can i drive my Acoustic Research AR-3A speaker with this amp?

[@JimmShaffer-vr9wu]

I'm seeing that 2 online companies here in the Philippines, Lazada and Shopee are already carrying the Max with 36v and 48v.

[@Panslapper]

I’m no audiophile and least as far as I know so far but these amps didn’t make my coffee taste any more coffee like…they do however give a great signal to my Q Acoustic 3030i which are a warmer speaker, very sit back and relax rather than get up and dance kind of speaker at least that’s what I think so far as I have only had them for a couple of days…I still think the Wharfedale 12.2 might have been more my wave but the 3030i admittedly makes it hard to leave the get up of the couch and leave the room.

[@larrygaines7462]

The hipass 70hz attenuate 3db so I preamp with douk amp. (5532) the open baffle dual 2's and beston ribbons, 8 in carbon fibertowers sum to 92 db/ watt. My phone shakes, and scares me with the dynamic range on female singers. KZbin premium music only, signal sub fringe, -125dBm,20 asu Low budget tech..

[@bobstinker2074]

Love the ao7! Couldnt tell a difference A/B between it and the Rotel a12

[@jerrypowers7671]

Did you actually listen to them over 60db?

[@MechAdv]

You must have very sensitive speakers or a bad source, because I can 100% hear the difference between my A07 and my AXR100, but I’m running 3-way towers with drivers that love power. The A07 with the 36v6a PSU absolutely runs my towers, but the bass extension is rolled off completely in the mid 40s, where I can measure bass response down to the mid 30s with the Cambridge audio with tone controls set neutral.

Lol!! That sweet, sweet affiliate income! Love it

[@6StringPassion.]

I just sent Aiyima a question using the "Ask an expert" form on their site. I wanted to know the continuous output in bridged mode at rated distortion of .007 thd. The acknowledgement upon submission of the form reads: "Ask the Fashion Expert anything on Ella Boutique". I am not confident a fashion expert will be the ideal resource. Are style watts a thing now?

[@dannygonzalez0861]

You won me over with the kid!! I'm a father of two girls as well so yup, permanent sub here lol keep up the great videos! Can't thank you enough for the information.

[@joelcarson4602]

I guess no one realizes that there are expensive, high quality class D amplifiers out there with tons of serious power and are designs built out of discrete components and are not "chipamps" ? Plus, there are any number of class AB amps out there that are low power, low performance and have poor efficiency, both tube and transistor. It's all about use case. The ridiculous 300 watt ratings are at a teeth grinding level of at least 10% distortion, and that's according to the Texas Instrument product specifications sheet. At sane power output levels it more like 30 watts or so at 8 ohms with somewhat under 1% distortion. Plenty of power to drive the majority of consumer bookshelf speakers to fairly brisk listening levels. I think the 48 volt 6.5 amp power bricks main function is really only to provide a little extra power reserve for bass transients.

[@boyderic]

Love your content. I’m an enthusiast, but the audiophile price point kept me away up until relatively recently. This may be a silly question, but it’s an honest one; is an amp like the one in this review paired with a SMSL SU-1 preferable over something like Sony’s STRDH190 strictly for the footprint/size, or is the sound quality simply better?

[@cheapaudioman]

Personally I’d rather have this and an SU1. Keep in mind the Sony is traditionally distributed where the retailer is selling it is making 50% on top of whatever the retail is. And the Sony doesn’t have a DAC

[@LBCAndrew]

@@cheapaudioman The Sony lacks a DAC but it makes up by having Phono, Bluetooth (wouldn't that mean is has a DAC?), multiple RCA inputs, a remote, and I got one for my parents for only $100 last year. Also, if you think Amazon isn't making 40-50% on the the SU-1 or Aiyima A07, you're crazy. lol.

[@cheapaudioman]

@@LBCAndrew well I’ve talked to multiple people selling on Amazon. BT chips have integrated conversion in them but is separate from a traditional DAC chips for inputs. I’m glad you like the Sony. And thank you so much for watching. It seems like you know a lot about this hobby and components. You should start a channel. I’ll actually share it out to help you get it off the ground.

[@lwdp74]

Is it possible to be toooooo cheap? I’d like to see a review of Topping’s 90 series, from preamp to their cables (available from shenzhenaudio) and the new TOPPING D90 III dac. I’ve been adding to the collection with used devices, when available but I’m still a bit short of affording the whole collection. So far my ears are pretty happy. $1,201.09 for a dac is not extravagant when compared to the esoterica out there. Sure, a hundred dollar amplifier 😊may be quite enjoyable but there’s affordable betters. PS. I’ve got a pretty good collection of interconnects and the Topping’s define transparency. Wish I could borrow stuff like you!

[@jimmyrustle6725]

What model sparkos opamp does this require?

[@chrishamilton5960]

Kind of wish they would stop with the 300 watts into 4. No one has been able to even come close to that number even with 48v 10 amp power supply. I bought the Fosi V3 with 48v 5amp supply and ended up selling it and replaced with an old LINN LK100 which just sounded better especially in the bass.

[@yttean98]

Awaiting your comparison against Fosi Audio V3. Similar price and same chipset.
