Package
Build quality
In terms of size, it is quite compact. Compared to the AIYIMA A08 Pro, which uses the same amplifier chip, the depth is a little longer, but overall the model is very compact.
Review
Maybe one day this will change for for now, in under $100 range you can't expect perfection in performance of a stereo amplifier. What you do want to see is delivering healthy amount of power with close to our average of all of our amplifiers tested to date. On that front, the Fosi Audio TB10D delivers. If you need an amplifier for secondary use (bedroom, workshop, etc.), the TB10D is a very good candidate for no more money than one or two dinners!
I am going to recommend the Fosi Audio TB10D amplifier.
Final Words
If you are looking for a compact power amplifier for a personal space, the Fosi Audio TB10D is an easy and convenient choice. It is not an outstanding model, but its cosmetic performance is probably above standard for most people.
Although the output claims a maximum of 300 watts for a 4-ohm speaker, the practical level is less than 100 watts. It is also inferior in overall specifications to the AIYIMA A08 Pro, which uses the same amplifier chip and is a standard choice for the price. It is an extremely simple power amplifier with a simple input/output configuration, no special functions, and no remote control.
In terms of sound quality level, it theoretically has a dynamic range that can handle almost CD level, not to mention vinyl records, and there is no shortage in its price range.
Most people will have no complaints in their daily use, but those who want to pay more attention to functionality, sound quality, and above all, appearance, should consider the AIYIMA A08 Pro at twice the price. Since they use the same amplifier chip, the sound quality tends to be very similar, with the AIYIMA offering better overall specifications.
