If you are considering purchasing a stereo Class D amplifier and you don't require Bluetooth or digital inputs then the Fosi Audio TB10D is a great choice. The TB10D stereo amplifier, when paired with a small music streaming device such as one of the WiiM music streamers (also available on Amazon), becomes half of a shoebox sized streaming audio system. You would just need to add a pair of passive (non-amplified) speakers. The bass frequency response of the TB10D was noticeably absent when first powered on. After about a half hour of operation the bass finally showed up and all was good. I leave the TB10D powered on as the standby power draw is very low. Even though I know that the location of the bass and treble tone controls on the TB10D are reversed, as compared with most other amplifiers and receivers with the treble control being on the left and the bass control on the right, I routinely forget and grab the wrong tone control. The speaker binding posts are small and close together. This is not an issue as I use banana plugs when connecting the speaker wires to the TB10D. Note that there is no headphone connection on the TB10D for wired headphones. If you need a small, inexpensive good sounding headphone amplifier for wired headphones consider the Fosi Audio P2 headphone amplifier.The TB10D's available output power, ~50 Watts per channel when used with 8 ohm speakers, with the included 32V/5A power brick is adequate for use in my kitchen audio system. The case and power supply of the TB10D remained cool to the touch even after extended listening (I measured 72F). If you have a large room, lower efficiency speakers, or desire audio levels exceeding ~85dB you should consider a more powerful amplifier. You can change the supplied external power supply for one rated for 48V, however this will increase the overall cost as well as increase the operating temperature of the TB10D. Within its limitations as far as output power, input options (one pair of RCA connections, no digital inputs), outputs (one pair of stereo speakers), no Mono mode switch, no BT, no headphone connection or remote control, the Fosi Audio TP10D is a very good choice. I found the sound of the TB10D when powering 4 ohm, 6 ohm and 8 ohm speakers to be consistently smooth, full sounding and non-fatiguing with a variety of music even after prolonged listening.I assembled a complete 2-channel audio system of exceptional value that can fit in a shoe box. Each of these products is currently available on Amazon. I chose the Fosi Audio TB10D amplifier that is the subject of this review. I added the well reviewed, amazingly compact WiiM Mini music streamer. I chose a pair of desktop passive bookshelf speakers. This system is capable of filling almost any size room in a home with great sounding music. The TB10D amplifier's tone controls and the WiiM Home app's equalizer settings can be used to adjust the bass/midrange/treble output of the speakers.

This is good little digital class amplifier. It has reasonable volume (power), it opens up with bass and treble at max. Sound quality... Well it sounds quite good, no distortions, clean, good punch on low frequencies. Fit and finish is very good, yes power adapter is bulky, laptop like brick, with bright green LED. oh well... For the price it is surprisingly good system.But be realistic...Its modified stock design, it is based on Texas Instruments "typical application". Included power adapter 32V DC 5A brings it to apx. 60-70Watts per CH... not 600Watts total, LOL - that would be at 53V DC and 2ohm load, 10% distortion and for a very short time. (Here: TI lab test: 600-W Mono into 2 Ω in PBTL Configuration)Don't try higher voltage power supply, capacitors and other components WILL FAIL !No, it is not AB class, it doesn't cost near as much either, you can't compare it to Cambridge Audio, Rotel or Marantz for $800 up, but as an auxiliary amp for mid size application it is great.

ottimo prodotto molto potente buonissimo l'audio

Die Stereoanlage ist schon auf den Müll gewandert. Der Plattenspieler selbst stand lose auf der Stereoanlage, wobei der Ton über die Stereoanlage lief und dort verstärkt wurde. Es wäre schaden gewesen, auch den funktionierenden Plattenspieler weg zu werfen.Am Ende war das einzige Problem, wie man den Sound des Plattenspielers so verstärkt, dass er auch aus den Boxen (ohne eigene Stromversorgung) zu hören ist. Ich habe folgende Verstärker kombiniert:1.) Sound des Plattenspielers geht in einen Vorverstärker (Hama Stereo Phono-Vorverstärker PA 506), ohne hört man zwar was, aber befriedigend ist das nicht;2.) Sound aus dem Vorverstärker geht in diesen Verstärker (Fosi Audio TB10D 600 Watt TPA3255), welcher auch mehrere Regler für den Sound besitzt (Treble, Bass, Volume);3.) Sound aus 2.) geht in Boxen, die keine weitere Stromversorgung haben.jetzt kann man ordentlich aufdrehen. Einziger Wermutstropfen: noch zwei Netzteile ...

I used this Fosi Audio TB10D TPA3255 600W Power Amplifier to connect a TV to old 100W Jensen Hi-Fi passive speakers. The sound that this little amp put out was so clean and high quality that I was blown away! With the volume at 10 O'Clock on this amp, the sound was plenty to fill a large sized room with crystal clear clarity of voice output from the speakers. Of course the Jensen speaker is a good one but this amp put out a real good sound. The TV was connected to a mini DAC via optical cable. I bought this DAC from Amazon too and works just fine for PCM audio. The DAC was connected to this Amp with RCA cables. Hey presto, great quality sound. Don't go past this little amp for home spaces .. sounds absolutely great!

This little amp drives my 3-way speakers very nicely. Nice clean sound and bass. It's small and compact and will save you space on your shelf, desk etc. Good price too. My nitpicking downsides is that the power supply is fairly large, about half the size of the amp itself so it might not save you that much space depending where you want to put it. Also, if you want to use the full power of the amp you need a better power supply which I'm not sure where you would purchase one from. A quick look at Fosi's site found that they do not sell it but the power supply included should suit most people. The on/off switch is retro which is cool but it looks fragile and if it breaks then you're stuck unless it breaks on the on position. I do like the simplicity of it. No built in radio, remote control or bluetooth which is fine by me. No headphone socket but that's okay too as I have one on my sound mixer. Overall, I really like this amp and hope it lasts a long while!

Sound is quite good as long as you don't push it. I'd say it puts out about 50 usable watts into 8 ohms. Awesome size vs. performance. I adjusted the bass up a bit and set the treble back a bit and overall sound is pleasant. It is presently hooked up to medium sized tower speakers. It is being fed by a Wiim mini and external DAC of a Music Hall CD player. It is in a relatively large room. So in summary not a bad experience at all. Could be a good place to start your musical road.

I bought AIYIMA A07 before because I watched "cheap audio men" comment on original Fosi Audio TB10's many problems (he updated for new upgrade version and recommended it). Now, Amazon has upgrade Fosi Audio TB10D on sale and at that attractive price, I can't resist not buying one for a test. So, I purchased one and it arrived on time. Here is the my two penny's opinion.In appearance, both machine looks great. Aiyima A07 looks more dedicated for high quality (with precise volume indicator), while Fosi TB10D looks solid and durable plus treble and bass control which for some music is quite useful (not much for vocal) The body looks 10% smaller. Both transformers listed for 32V 5A even same model number. But TB10D's transformer looks 10% smaller. I believe this is because TB10D comes later in market and using newer parts (though same chips). Over all I like TB10D slightly more except one thing: no 3.5mm plug in and you have to buy a 3.5mm to RCA cable. That may be the reason some buyer who only use for computer speaker will choose A07.For sound quality, Aiyima A07 is just pure great sound even there is no treble and bass control. The upgrade TB10D has basically same level of great sound as A07. I am using my KEF LS50 bookshelf speaker for comparison and they are equally great. With treble and bass control, TB10D give you a little bit more flexibility.Over all, I would not regret recommend TB10D & A07 as both are great mini amplifier with pure sound. Plus now, at such a discount and A07 increased price a lot, TB10D is really a great deal. I usually buy hundreds items every year from Amazon and seldom write any review. But this TB10D at such a value worth me to write a review. I used two days now and I am very happy with it.
