TB10A

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.

I really like this little amp, it works perfectly for my backyard movie night setup driving a pair of 4ohm weatherproof speakers. It sounds good, will get loud enough for outdoor movies or gaming, and has a nice output gain range for quieter listening or to "crank up the volume" a bit. I have my outdoor system components just stuck on a piece of wood so I can pick it up from where it's stored, put it down on an outside table, and plug in to power and the speaker lines that live inside an electrical box by the fire pit. Its small size and weight is great, and the price is excellent. Has lasted about a year so far with no issues. My one nitpicky problem (that costs a star) is that the output terminals are spaced in such a way that standard 2-prong banana plugs don't fit. Well -- they do fit, but between the left and right positive terminals, and the left and right negative terminals, which would result in incorrect wiring. The manufacturer should change the order of the terminals on the back so these can be used correctly. Given the amount of space on the back, maybe clamp terminals would be a better choice.

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.

I bought the DB10A (Updated) for use with a desktop computer. The amp has bass and treble controls without bluetooth. I have a Definitive Technology Pro Cinema 800 home theater system that I upgraded with a much larger sub and bookshelf speakers for the fronts. I'm using the Definitive sub and 2 speakers with the Fosi amp. I'm very pleased with this setup. Music and games both sound very good. I have the treble and bass both at about 2 O'clock. There's plenty of volume available and the amp stays cool to the touch. I'm only a few days in at this point. Completely satisfied, especially considering the cost and size of the amp. My sub is self powered. I connected it to the amp using speaker level inputs, then connected the speakers to the outputs on the sub. It's working really well connected this way. I don't have to fiddle with the sub at all. I didn't use any banana plugs, but would recommend using them. The connections on the back of the amp are small and packed tight, banana plugs would have made it much easier.

Bought two of these right before I moved, and put them aside for a few months while I got settled in. Set up my record players and found that one of the units wasn't putting out sound on one side. Switched up the wires, checked the inputs and switched units. Sure enough, one unit was defective. Contacted customer service and got a reply fairly quickly. They gave the usual advice, asked questions, and asked for video proof. No biggie. Took a couple of days of back and forth emailing, but they had a new board shipped out really quickly! Got the new board and was able to replace it quite easily, and it works amazingly. The sound is great and it's really compact, and does not feel cheap at all. I love it, and will definitely buy from these guys again!

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.

Bought 2 of these to use in a 4-channel quadraphonic surround setup after my Yamaha receiver failed after 21 years of 24\7 service,. The reason I chose these, is due to the fact MODERN A\V receivers that you can buy NEW today have removed their ability to do analog surround sound and must do it via HDMI or Optical, which is not how SURROUND SOUND works for PC. Very few soundcards even support 5.1 over dobly\dts over their Optical outs due to licensing crap and when they do support it, there is always issues of some kind, from latency cutouts to CPU usage (looking at you Sound Blaster ZXR). My primary application for surround is PC analog out and these fit the bill nicely and are just as clean as the YAMAHA receiver they replaced, somehow at a fraction of the price. The people complaining about hiss are obviously hooking these up wrong or to OLD\Junk noisy gear that already is producing it, I might even dare say these amps are cleaner sounding then my OLD receiver, their only downside there not as powerful, but I don't need them to put out sound you can hear a BLOCK away, just enough to fill a room loudly and these do it just fine, but like I said I AM using 2 of these amps at the same time 1 for the front channels 1 for the back channels if I wanted to go to a 6-way setup I could easily with a 3rd amp and I'm contemplating getting another one this time the model with sub output and go 6.1 fully.

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!
