The upgrade version is better than I expected
5 out of 5 stars
The upgrade version is better than I expected
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, 鶹 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 鶹 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.

    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.

    How does it sound?

    I conducted a comparison between the Onkyo RZ50 in pure output mode (RCA) and the BT30D Pro (RCA), both using RP5000F towers and an amp selector switch. I was unable to hear any difference between them, which is good news. It appears that the well-implemented TPA3255 chip sounds the same in all cases.

    Everytime I plugged in the male power plug, there were sparks. I can see and hear it.

    The power measurement:

    Setup:
    RCA Input signal @ 1000hz, 1Vrms
    Tone control at half way

    L & R both driven, 8 ohm load, 50W rms per channel, before clipping. Volume knob at 2.5 o’clock

    L & R both driven, 8 ohm load, 60W rms per channel, clipping, Volume knob at 3 o'clock

    L & R both driven, 4 ohm load, 85W rms per channel, before clipping. Volume knob at 2.5 o’clock

    I wasn't able to reach clipping at 4 ohm load. Either the amp or power adapter goes into OCP protect mode everytime.

    Noise was tested at maximum volume. There was a barely audible hiss from the speakers, which could only be heard if you put your ear close to the tweeter. There is no circuit to shut off the signal because it is not audible when sitting away from the speakers.

    The TPA3255 chips are efficient and can produce a significant amount of power for their size.. You can increase the power output of these chips by upgrading upto 48V power adapter. However, because on the heat issue, I wouldn't do it unless you modify the enclosure with active cooling.

    It appears that many manufacturers using this chip have set their power limits based on the capabilities of the power adapter.

    Pros:
    Great build quality
    Excellent sound quality, to my ear it’s on par with the RZ50 and BT30D Pro
    Low noise floor
    Excellent price / performance ratio

    Cons:
    Thermal management
    Sparks

    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.

    Ich besitze eine alten Samsung-Plattenspieler, welcher von einer alten und kaputten Samsung-Stereoanlage stammt. 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);
