- TB10A 2 Channel Stereo Audio Amplifier Receiver Mini Hi-Fi Class D Integrated Amp 2.0CH for Home Speakers 100W x 2 with Bass and Treble Control TPA3116(with Power Supply)

I was looking for a small unit to replace an LG bookshelf stereo I was using with a pair of paradigm atom 7 bookshelf speakers. I found this fosi amp with 1 analog in and though I'd give it a try. Upon hookup and having my first listen I was totally blown away at the sound. The LG system I was using before pushed 550 watts before but that system had 2 bookshelves and a sub that went with it and I never got the sound out of my paradigms with that like I do now with this fosi amp. Clean and clear sound is how I'd describe my sound now with this fosi amp. Call me impressed fosi but this is incredible for such a compact amp. I will be ordering again if I need an amp for a garage setup or something. If any of you are in need of a small amp for a pair of bookshelves with only one source needed give this fosi a serious look. IF this thing last it will be a jewl in the audio world. Thanks again fosi for a great product. *UPDATE* I was so impressed with this amp powering my paradigm bookshelf speakers that I had to buy another. I have definitive 9060 towers in a stereo setup and I use an emotiva pre amp with a crown xls 1002 amp. The crown puts out 215 watts into 8ohm. I wanted to see how this fosi amp worked with my towers so I hooked it up and hade a listen. Wow is all I can say. I love the fact that this amp has tone controls as well. This amp drives my towers no problem so far and I am impressed I can run them off this amp. If this thing lasts I will be very happy... It has a great warranty but I did buy the 4 year extended. Thanks again Fosi. *Update 2* I wanted to say when I turn my amp off via the front switch the red light goes off. This is probably due to this updated version as a lot of reviews seem to be for the previous version and or the Bluetooth enabled version. I wanted to point this out for others. This amp is running like a champ still powering my towers and I'm loving the clean and clear sound I'm getting out of my deftech 9060 towers. It's like I have new speakers... Lol... My other fosi amp will be here tomorrow for my bookshelves. I'm just giddy that's this amp does this well compared to what I've used before.... Awesome product... Just want it to last but so far has ran very cool and quiet... I Love these little but powerful amps... 😊

When my Dayton Audio AP102 finally lost the left channel, which was weak since it was new, it was time for a new amplifier for my zone 2 outdoor setup. The AP102 lasted about five years, so I have no regrets, other than the persistent weakness in the left channel (which was "remedied" by use of the balance control). I looked at the newer, class D version of the amplifier, but the price had almost doubled since my initial purchase. I was curious to try the new "chip" class D amplifiers, so I started looking. I have had good luck over the years dealing with Parts Express, so I still have good feelings and nothing at all derogatory to say about them...Amazon Prime is just more convenient for me. After trying the Aiyima A07 and finding it unsuitable in my situation due to the lack of bass from my four Dayton Audio IO655s and no way to attenuate the treble nor boost the bass, I decided to try the Fosi TB10A2 primarily because of the included bass and treble controls as well as its reputation for being a more "warm" sounding amplifier. It's tiny, about 2/3 the size of the Aiyima. While I must give a slight nod to the Aiyima for elegance of construction, the Fosi is still nicely put together. When I first got the Dayton Audio IO655s I had one pair on the covered front porch and another pair under the house (which is on pilings). The lack of bass was so radical after I moved my Kicker KB6000s out to my shop, that I had to resort to using a powered subwoofer on the porch...the Dayton Audio SUB-1000, which was a game changer. I was concerned about using an MDF enclosure even on a covered porch...but it has held up extremely well despite the Florida humidity. The under house speakers had to make it on their own. The Dayton Audio AP102 was a class AB amplifier and had (rear-mounted!) bass and treble controls, so it was able to make the under house speakers sound okay. This little Fosi is amazing! the channel separation is worlds better than what I had with the AP102. The treble and bass controls thoroughly tamed my bass shy speakers and all is well once more. The AP102 was rated at 60 watts per channel, the Fosi at 100 watts per channel. Neither of these figures are real world numbers. That said, the Fosi gets far louder without breaking a sweat than did the AP102. It runs totally cool and the vastly improved soundstage really improves our listening experience. Highly recommended.

Compared to my fantastic-sounding class AB amplifier, the Fosi TB10A is a significantly more modest class D amplifier that costs one-eighth the price and can’t be expected to perform at as high a level – and it doesn’t. Am using the TB10A in a secondary system with a Blu-ray player and HDTV, and using floorstanding speakers rated at 96db (the same speakers that connect to my class AB amp) can readily hear that it has a clear but nonetheless dry and lesser dynamic tone to it. With this type of a restrained sound, it’s certainly better suited to TV shows and movie viewing than music listening. As such, and exclusively from an acoustic perspective, the TB10A is very much a utilitarian amplifier. This is not a criticism, just a frank evaluation of its plain and lesser inspired sonic performance. Despite this critique, this amp seems solidly built, the knobs are smooth when you turn them, the bass and treble adjustments do their job nicely enough, and the power supply looks well built and feels hefty. With the source material being a TV show, have turned the TB10A up to just half volume and it was clear and free of audible distortion. For less than $63, this is a perfectly fine amp, just not one that breathes life and grace into what it plays. It should serve you well as long as you know what to expect of it.

I've always been skeptical about these little "Class D" amps. I discovered them when people started buying the Lapai LP series, but I held out because they just didn't seem like quality to me. Fast forward to 2020 and we now have lots of "high end" mini amps such as this TB10A from Fosi. All I can say is that this thing doesn't disappoint. My main concern with such a small amp was volume, so I tested these out on some full size tower speakers - one's that aren't very efficient and need little extra gain compared to my other speakers. Surprisingly, I was able to blast those things! I've got two very powerful home theater receivers that can obviously get the job done without even trying, but at 80-90% volume, this amp held it's own and put out enough power to play music at house party levels. This amp is MORE than powerful enough for a bedroom, and good enough to fill a basement or living room with loud sound. The other important thing is obviously the sound quality itself. I can't say anything negative about it. I didn't notice any hiss, distortion, or artifacts of any kind. The sound was clean all the way to max volume. Furthermore, the tone controls are entirely functional. A minor annoyance is that the "flat" position is 12:00 for each knob, but there isn't any notch that holds the knobs in place, so you really have to eye it and make sure both knobs are equal in order to get a flat response. Once moved from that flat position, the sound changes dramatically, but in a pleasing way. You can very easily add some high end sparkle or low end thump without ruining the natural sound of your expensive speakers. As for the little quirks, I encourage the use of banana plugs because the speaker wire terminals are smaller than average and it's really difficult to get the wire in there. The amp itself feels well built, but due to its size, it is very lightweight so I would recommend securing it with Velcro or 3M command strips if doing a semi-permanent installation. With that said, this is the perfect device for a mobile or portable speaker setup. This is exactly the thing to use if you're setting up speakers in an office or gym short-term. I give this product a 5/5 because for the price ($70), I can't imagine getting anything more. It is NOT the loudest, best sounding, most feature-rich amp out there. But for such a low price and such a small form factor, it is well worth the price.

Replaced a 40 year old Realistic/Optimus/RCA mini amp with this. I am using this to drive a pair of Klipsch bookshelf speakers in my studio where I do voice overs and produce radio commercials. This little bugger takes up virtually zero room, sounds great, nice clarity with no distortion, and no extra fluff that you don't need to get the job done. It seems like a small detail but I like the mini flip style power switch. Easy to turn on and off. Previous little amp and a different one I also use in the studio have either push button switches or rocker switches and pressing them requires using the other hand to hold the small amps to prevent them from being pushed back on the shelf. The little flip switch eliminates this irritating little issue. Be sure to pick up banana plugs or get cables that have them, for speaker connections. Includes a nice solid power supply. Not some crappy wall wart. AC cable from the wall to the power supply, and another built in cable that goes to the amp. Only complaint (and it's a small one) the cable that goes from the power supply to the amp itself could be longer. I prefer to leave the supply on the floor out of sight and just run the cable to the amp. The cable from the supply is too short for this. Had to stash the power supply up in the shelves and run the other cable down to the wall socket. Not a big issue, and certainly workable but another 2-3 feet on the output side cable would have been nice. Nice amp, great sound, plenty of power.

Small and light with plenty of power. I like the tone controls and the marked knobs (makes it easier to find a particular setting). AS for the sound, I found very decent stereo separation and a nice "soundstage" (of course, your speaker placement will effect that.) I bought 2 and use them as part of a desktop PC system. Connected to the PC via a Schitt stack (Modi 3+, SYS, Loki, and Magni headphone amp). I separated the signal from the Modi 3+, Loki and SYS and split it off to the amps, with a separate pathway to the Magni (so I can bypass the Fosi amps when using the headphones). The Fosi amps are running 2 satellite/ subwoofer systems (an amp for each system) and I use the SYS as a master volume so I can leave the amps as I have them set. (to better blend the sound of the different speaker systems ( a Design Accoustics sat/sub system and a Genesis Media Labs passive sub paired with a pair of DML type speakers I made.). Anyway, I very happy with the whole setup and it lets me use my PC as a jukebox! The sound is good both near field and far field!

I bought this unit 7 years ago and I like it so much I decided to go back and write this review today. This little amp paired with a quality pair of bookshelf speakers is shockingly good. Very loud and very clear. I can tell you their customer support is outstanding also. I damaged one of the binding post connectors in a recent move. I sent Fosi an email and they are sending me a new set of terminals for just $10 including shipping.

This thing rocks! Wow! What a great value. So much power in such a convenient small but well built package! I was a bit worried about some of your other reviews mentioning Sparks if you don't plug it in the right order but I've done it a couple of different ways with no problems. In the video you see I am hooked up to a Schiit Modius DAC and Schiit Magni Heresy connected to a Sony UHD player w a Beatles CD playing on a pair of Emotiva Airmotiv B1+ speakers. They sound amazing with this setup. I couldn't be much happier and would highly recommend this amp. I have no affiliation with Fosi Audio or Amazon in any way shape or form. I'm just your average guy who is really excited about listening to music with some cool new equipment. obviously this is not top of the line stuff but I think it's a great value and can really enhance your enjoyment... whatever you choose best of luck to you! One more thing... Look at how low the volume knob is in my video and consider this is coming through my cell phone, there is so much headroom and strong clean power coming out of this, it's just awesome!

good quality of sound i use it to make my onkyo surround system 7-2-4-4 speaker setup for my rear speakers

Eventuell habe ich ein Update erwischt. Ich habe keinerlei Nebengeräusche, die Regler funktionieren einwandfrei, Höhen und Tiefen verändern sich hörbar, ohne den Klang zu verzerren. Die angegebene Ausgangsleistung ist natürlich quatsch. Ich schätze so 25 Watt pro Kanal, was mehr als ausreichend ist. Angeschlossen sind MK40 Teufelboxen, die sehr laut sein können. Das Netzteil wird lauwarm und zeigt keine Anzeichen von Spannungsclipping. Die Büschelstecker passen bequem nebeneinander. Der 24 Volt-Eingang hat zusätzliche Haltefedern, der Stecker sitzt bombenfest. Mit Sinusgenerator gemessener Frequenzgang +-3dB ist 45Hz bis 18,5kHz. Mehr als der TV anbietet. Ich bin zufrieden. HiFi wird eingehalten. Die kleine Kiste erstaunt mich. Meine Empfehlung für Flachbildschirme über Analogausgang. Dadurch über Fernbedienung (Lautstärke) direkt steuerbar. Ist S/PDIF dadurch überlegen. Da muss man nämlich am Gerät selber kurbeln, da keine Fernbedienung vorhanden ist.

Bought this to power an old pair of passive speakers and it’s been great. Setup was simple, it’s surprisingly powerful for its size, and the sound is clean. What impressed me most is how quiet it is. No hiss, hum, or other background noise through the speakers when nothing’s playing, which I wasn’t expecting from an amp at this price. The bass and treble controls are useful, and overall it feels like really good value for money. I love how it’s so compact!

”Diskret” storlek. Gör sitt jobb men ganska grovt ljud.

Il en envoie ce petit machin sans pour autant saturer il sonorise la salle de bain sur deux petites enceintes de 60w et lecteur usb que du bonheur et tout ça sans pub...
