[@MrLoup24]

just got banned from Audio Science Review because of this review. I googled a Geshelli Labs amp and saw that they did a review of it. I really like their products. anyway someone in the comments was dumping on Geshelli and made a statement about "bespoke" products being useless. so I replied to him and pointed out "the error of his ways". so someone else comes at me and I see he has a post regarding "Cheap Audio Man and who would ever listen to him. Well i replied with a link to this review and stated that apparently Fosi Audio does. so the wolves came for me and this is when I realized that these are the folks that you refer to in your audiophile rants and I assume that you are mocking the guy who runs this site in your early speaker shootout videos when you put those random statues on the speakers. never really knew why you did that. now I know. 🤣 anyway, I enjoy your stuff.

Oh my god I laughed when you mentioned Ifi as taking criticisms poorly. I was outright lied to and stone-walled by their customer service rep when I reported that my DAC was dropping out occasionally and provided all the useful diagnostic information I possibly could. All I got from their end was gaslighting and passive aggression, nothing constructive. It kills me inside when manufacturers make very good products that I happily praise to no end, only to get kicked in the teeth by their toxic customer support. Fosi Audio are chads for responding constructively and I hope nothing but the best for them.

Thank you Randy. I have the first version and only use it to have speakers on the deck. Ok for background sound. I hooked it up to the Klipsch Chorus and wasn't impressed. Never bothered again. After watching this review and making a rare impulse buy because you had me curious. Hooked them up to the Klipsch and I was floored. Compaired to vintage Carver gear (original owner) didn't sound quite as good, but $75 compaired to way more. Wow! Not even close to over a thousand dollar difference. It held it's own. Impressive. Fun to listen to. Wife out of the house so time to give it a workout. Literally knocked a picture off the wall and sound was clean. Not much impresses me. This did. Thank for your reviews.

[@jimshaw899]

A bit of fine tuning: The Aiyma A07 can output audio signal on the rear 3.5mm jack, but that output is not controlled by the volume control. Thus, it isn't useful for a subwoofer (unless you want to adjust the sub volume every time you change the Aiyma volume). I am using an A07 on my desk, and it says this in the manual. I have to use the speaker outputs to feed my speakers and subwoofer's hi level inputs. Incidentally, I am quite satisfied with the Ayima A07 for a near field desktop system amp. It is a tool; it just soldiers along. If I didn't already have passive speakers on the desk, I would likely have just purchased a pair of powered monitors.

[@greganderson1681]

So......I bought a 2nd Fosi and now run them as mono blocks using the right chnl of each one to driver a Forte'. WOW the soundstage opened a ton; like never before.

Well, the unit came in and I set it up via an old Sonos ZP100 Connect through some Wharfedale Diamond III's in my bedroom, and my god... This thing sounds amazing!

My really old (and big) amplifier is starting to warm up quite a bit even in stand by and it has to go before it sets in fire 😂 My budget is limited, I dont't require a whole lot, I want something small and I really like the way my old speakers sound. They might not be the most accurate, but I just really love them and I save money by not buying active speakers.

[@brunohebert1351]

It was indeed the proper way for Fosi Audio to respond. Now, question: is the new TB10D worth the upgrade over their TB10A for a desktop environment (which I'm quite happy with)? Basically it's 1xTPA3255 vs 2x TPA3116 ( is it one per channel?) BTW, the TB10A is now $56 ($70 -$14 coupon) which is also a pretty good deal if you don't need tons of power (rated at 100W/8ohms)

[@williamnaman3570]

I just installed this with Buchardt S400++. Caution if you use Speaker connectors with large metal barrels. The speaker jacks flex enough to short. I put a playing card as an insulator parallel to the tabletop, between top and bottom jacks.* note: metallic embossed playing cards not recommended. The fosi doesn't sound as good as my Denafrips Thallo, but is not broken in. I switched to tuneful Belden 9497 speaker cable and heard a noticeable difference in tone. The cable costs slightly more than the amp. A company called ballastshop makes custom power bricks. Recommended 36v and 8 amp power brick. I paired this with JBL 530 speakers and there was some synthesis. The highs were not as good as expensive speakers but both covered each other's weaknesses. This amp encourages spending your budget on your speakers.

[@marks-the-spot]

Thanks for the recommendation, Randy. I replaced a 5-year old SMSL SA50 with this amp. My PC desktop with Behringer UMC202HD DAC and vintage ADS 300 speakers is improved in every way. The soundstage in this nearfield layout is surprisingly good. I am puzzled why the Treble knob is on the left and the Bass is on the right, never seen that in any amp/receiver I have owned in the last 50 years. But that's a minor niggle given that I'll probably set them and forget them.

[@tombradfiled9342]

Just want to respond about the TB10D. You did not oversell it, the little Fosi is everything you said it was. I went ahead and hooked it right into my main system and its driving my Wharfedale Linton's very easily and surprisingly has very ample power on tap for them, The WiiM Mini with a Cambridge Dacmagic Plus is the source. It is amazing how something so inexpensive can be so good.

[@ramondelgado6778]

Are you still using the TB10D on the Wharfedale Lintons? I’d love to hear your thoughts!!!! Thank you!

[@spectrelayer]

Randy: So good to hear a reviewer speak well of tone controls. As you know - because of the variances in simple loud-speaker characteristics - being able to raise or attenuate the extreme ends of the sound spectrum is almost a given. The ends of the spectrum are where most speakers show their weaknesses. Having tone controls that have wide "Q" settings for under 100 hz for Bass & centered at 12khz for Treble is a BIG FREAK'N DEAL. Best wishes.

[@tskolits]

Really loved this video. Thanks for doing this. Some great options here!

[@mr.b4444]

I received the unit today and all I have to say is wow. I hooked it up to a Cambridge Azure 851N and Emotiva T2+ speakers. I'm a bit shocked out how well it handled all the music I threw at it. I played it for a couple of hours and it didn't even get warm with a 4 ohm load. I had it turned about a quarter of the way up and it is loud and clear, great separation and imaging. No noise during quiet passages. What would be nice on this unit is maybe another set of RCA inputs and a sub woofer out. But for $72 I'm still amazed. One thing I learned from this is to question my spending on systems that cost 20x as much and don't perform any better. It's just a basic no frills amp with no bells and whistles that sounds great. Thanks for this tip Randy.

[@ChihuAudioMan]

Great video Randy! Based on your comments, it sounds like you need to roll the op amps on the Aiyima A07 (which I have done) to match the Fosi TB10D, is that right? With the rolled op amps, do you like the A07 better than the stock TB10D?

[@sayubu]

Interesting product; however, one thing I cannot find is where the 'zero' level is for both Treble and Bass. Is there a 'zero' level and you can go down (left) and up (right)? Or is 'zero' all the way to the left (down)? Minor mistake from Fosi but huge for those who want to know the real level of gain.

[@clarencehoover6748]

Bear in mind that even though the TI chip may be capable of more power output, that does not mean the copper traces on the circuit board can handle the additional current. Consult the amplifier manual before attempting a larger external power supply.

[@cheapaudioman]

ha. I don't know if this thing has a "manual" Amazon listing says it can handle it. but yeah... check it out. not like 48 volt 10amp power supplies are available at Best Buy anyway

[@gracenotes5379]

...nor does it mean that the chip (or the case it is in) can dissipate the necessary heat for sustained periods. The power lost as heat from the TI chip will exceed 80W if the 2-channel output power goes above 550W total (into 4 Ohms). That's similar to a modern i5 desktop CPU power dissipation and we all know what those cooling systems look like.

[@cheapaudioman]

@@gracenotes5379 don’t know what to tell you all. I’m sure it’s not going to hit 300 watts sustained. Or even 150 watts. It’s a $72 desk top amp. It sounds good. If you want more juice you can get a beefier power supply. As it is, I think the 32 volt is good enough for 98% of people and speakers out there. If you need 300 watts Fosi audio probably isn’t the company to look at. I try to keep this stuff in perspective. But if you need 300 watts probably not the amp for you

[@gracenotes5379]

@@cheapaudioman I'm not complaining about anything - my intention is merely to help set expectations reasonably. Perhaps the TL;DNR is that the Amazon product headline that includes the 600W number is a misleading one. (It's a 600W chip, sure, but not a 600W amplifier as built.) Your mention of changing over the power supply might just have gotten some folks thinking in the wrong direction, even though I know you wouldn't want to encourage that. Peace.

Buy both Aiyima A07 and this Fosi amp. Use the full range outs of the A07 to run into the Fosi and let that handle your highs/mid highs and let the A07 handle the low end. Best of both worlds!! Assuming you use speakers that can be bi amped.

[@abunk8691]

Thanks for the review I'll be adding the TB10D to my wishlist haha. Normally just the unit itself is around 54 USD in my region and on sale about 42 USD. With the 32v power supply its about 52 USD so I might get it with the 32v power supply since I don't have any adapters that high of a voltage. I was considering the Fosi TB10D, Fosi BT20A, and a bare TDA7498E board. That TDA7498E is quite cheap at around 15 USD and I've seen other reviews of it and its not bad, but I think I should go up a bit in price for a nicer to use amp. Meanwhile the BT20A is surprising since its around 50USD so I'll have to decide which to get when the time comes.

[@rtpwyk]

Man, I had the opposite experience. I had a Topping power supply go south on me and I contacted Topping. I had the thing a while, so I just wanted to replace the powersupply - I didn't want to warranty it. I asked them how much it would cost, etc. They would not sell me a new power supply unless I gave them my receipt or product registration(I forget which one it was a year ago now). I told them I lost that thing a year back, and that I wanted to purchase a new power supply. They would not sell me one. We went back and forth several times, and it got more and more odd every time. At one point they accused me of not really needing a power supply and not actually owning the product. I just..I dunno what to say. I ended up selling it on without a power supply, and I won't ever buy a Topping product again. Just an odd experience.

[@cheapaudioman]

that is weird. I've heard that they've been having some reliability issues with the PA5 and even the new LA50

[@AudioHead809]

I’ve heard about the issues with the pa5 as well. Sadly I heard about it after I already bought one. Mines is still going strong after two months and I love the way it sounds. Fingers crossed, hope it lasts a long time. Definitely a pricey little unit.

[@LtJerryRigg]

This is great and all but FOSI has a huge issue with their external brick power supplies. As you touched on, the amp is rated at 600W but the PSU supplied only offers 160W! Even their suggested upgrade (48v 10A) only provides 480W. Purchasing such a power supply is quite expensive, and asking a 2.1mm barrel jack to handle 600W is also problematic. With an upgraded PSU the total cost exceeds that of other amps with integrated power supplies that actually reach their stated power levels. I had a Fosi audio BT30D that I purchased and returned because of these issues.

Been looking for a 48V 10A power supply myself. Found one ($40 AliExpress) but now I wonder about perhaps introducing noise. And also what you said about the jack.

Hi, thank you for your honest review. For some time I'm searching for a small amp to my now old Mission m73 speakers. Can this amplifier be a good match for my speakers? Thank you and keep the videos coming.

[@richardpena6201]

I sure do miss the old rickety table and blue table cloth. How about a CAM throwback day video? 😀

I just bought this amp for $47 on black friday.... I cannot even believe what I got. Sounds amazingly good pushing the Micca MB42X on my desktop. I am actually testing out some smaller Saiyin 3.5" 2ways on amazon that were $49 with a $10 couple ($39). The Saiyin combined with this cheap amp sound pretty dang good for $90 bucks. It certainly beats all of those crappy powered gaming sound speaker systems. In fact, the size and sound is so good, that I will probably move the Miccas to home theater duty. Free up some desk space.

I would love to know how to put that together with some quality $300 speakers that don’t need a sub and a worthy streaming source for my garage.

I got one with some little Klipsch bookshelf speakers to replace my buzzing mess of a computer speaker setup. Works pretty well. I feel like the right channel sort of cuts out when it's at very low volume, but I'm not sure if it's my imagination. Otherwise good performance.

@cheapaudioman HIFI noob here. Have a Yamaha RX-V777 receiver, 2 x Scandyna BigPod and 2x Scandyna The Drop; running on two zones through the receiver. I am however really annoyed at the capabilities of the Zone management on the Yamaha. Too querky. So.. I am on the lookout for a better multi room setup. I have been watching A LOT of your AMP videos, but I still don't understand HiFi 😵‍💫I have no idea whether these smaller D Class amps will be able to drive the speakers properly and replace the Yamaha receiver without too much of a downgrade. Do you reckon something like the TB10D or Aiyima A07 will be capable? One for each set of speakers of course, coupled with Wiim mini/pro for streaming services and multi room. Hope you'll be able to chime in. Anyway, thanks for great and entertaining content.

How do you tell the difference between the oder version and the newer one when buying used ??

[@ronzack4572]

You have the BEST commercials.

[@cheapaudioman]

Glad you think so!

[@StromBugSlayer]

So how do you know if you are buying the old version or the upgraded one? Also, you previously criticized its BT performance. Has that changed?

[@willjohnson9256]

I prefer the sound of TB10D compared to ZA3 monoblocks...it can easily drive my vintage 6ft tall Genesis APM-1 speakers (89dB sensitivity) .....sounds extremely detailed, neutral and very transparent...amazing bass. Connected directly to my CD player. I'm using the 48v 5a power supply from the ZA3....it can get very loud at 9 o'clock volume so most of the time I'm only set between 7 and 8 o'clock. Very detailed even at the lowest volume level.

[@JoeSmith-fw2jg]

This looks like a nice unit, but the SMSL AO100 is another great choice. That gives you a remote, digital volume control, digital bass and treble presets, subwoofer out, bluetooth, and about 45 wpc for 8 ohms. I love my Aiyima A07, was an early adopter for the SMSL SA50 years ago...so many good choices now for $150 or less, it's really just a question of the feature set one wants.

[@greganderson1681]

I’ve been using a Ridge wallet for a few years. Love it, but it’s wearing out. Maybe time for a change?

[@narikaba439]

Is there a way to tell if one is getting the original version from possible left over stocks from Amazon's warehouse? Is there a serial number range one should look out for?

[@blekenbleu]

How can one visually distinguish the original from updated TB10D? FWIW, works nicely with Denon AVR-4810CI.

[@cheapaudioman]

not sure. the new listing says "updated"

[@miba-Housemusik]

First of all thank you for all your great videos! Is it also possible to swap the op amps with Sparkos like with the Aiyima? I need an EQ, so the Aiyima unfortunately falls out.

[@TheUboat505]

Hi Randy! tried the upgraded TB 10 D good sound whit css5 and m20-3 but the recent bt 20a sounded cleaner thanks

[@robbedoes1985]

Did you get to review their Fosi BT20APRO also?

[@henriquenicolau]

How does one know if they're the first or second generation if they have the same name? thanks

[@hobblyjig]

I’ve never found a good 48v/10a power supply. Has any one used one with a class D amp that they like?

[@dvaoa2910]

Actually, $20 off coupon at AMZ. Just picked one up for $60! Great find, thank you. Can you recommend a beefier PS for this little guy that's not noisy?
