Title: Bring new life to old speakers - Reuse/Recycle
Content: RECOMMEND? Absolutely yes. TESTING: So far only 2hr of testing, but so far so good. Checked sound from headphone jack of phone to RCA of amplifier - works. Paired to same phone for Bluetooth – works. (had some trouble initially with Bluetooth range, but it turned out that it was the phone and not the amp). Paired to a different phone and had a great BT connection from across the house. SETUP: Running it with two 8Ω Bose 201 (L-R) full size speakers and one 4Ω Bose sub taken from a dead 2.1 system (sub still good, hockey puck died). Room is about 10' x 12' x 9’. PROS: This is a great way to re-purpose some speakers that were just sitting around gathering dust. Most of the controls are on the front of the amp and easy to access. Good price, good features, compact, decent power, clean sound, nice appearance, no hiss/crackle/pop, good connection options (RCA, BT, speaker lugs), has manual switch from RCA to BT input so that you don't have to keep disabling BT on your devices. Easy to use and way easy to setup. EXTRA: Wonderful support! I wrote them with an issue about my BT range, and they replied in less than a day. I was surprised. Even more surprised, they had a tip that solved my problem (try a different phone) CONS: The speaker lugs are a little close together, but that comes with this extra compact form factor. The mid-range seems a bit anemic, but I have not given the amp much ‘break in’ time. SUMMARY: Really blown away that such a tiny package can drive two full sized speakers and a subwoofer, and do it adroitly. I know, Class-D, but it’s still impressive to me. Produces WAY more sound than that room can handle, and then some. Audio is clear, crisp, and distortion free. Package is compact and sturdy, with convenient controls. I have no regrets so far about this amp and look forward to using it more. (and perhaps even getting a second one for another room)

Title: Easy, reliable amplifier for stereo audio
Content: This Fosi amp continues the great performance as the other non-Bluetooth versions have. It has an all metal case and feels solid. The audio comes out loud, clear and easy to adjust with the integrated dials for treble and bass. The Bluetooth connection was simple and didn’t require holding any special buttons to initiate. Sound quality was just as good as being directly connected through line in. One of the other nice features is the ability to change the on board op-amp. This process was easy to remove the three hex head screws and slide the board out. While I haven’t had the need to make a change it is nice to have the option in the future. I have multiple Fosi amps and would recommend them to others. Their support is quick to respond if any issue arises and warranty support is needed.
Title: Nice little amp
Content: I purchased this amp to run a 2.1 system in my garage. What attracted me to the unit was the small form factor, built in Bluetooth, bass and treble controls and the active 3.5mm output for a sub. I connected the amp to a pair of Sony SSCS5 speakers and an older 10" sub I had to the 3.5mm port. Connecting my Android phone was quick. My phone saw the amp right away. It would be nice if a password was required to ensure no one else could connect to the unit. The sound quality was nice and the unit had more than enough power to run the Sony speakers to the levels I needed for listening in my garage. Bass and treble adjustments sound nice, not digitally enhanced. After an hour of listening the unit got a little warm, but not hot. My only gripe, and the reason I removed 1 star, is that the hashmark on one of the knobs is misaligned (see pic). Seems like the quality control isn't quite there, but overall I would recommend this unit.
Title: Me sorprendió y cumple con su función
Content: Ya a más de un mes de probarlo me sorprendió lo potente que es, muy práctico de usarlo y sus perillas para ecualizar de lo mejor, la conectividad del Bluetooth estable, estoy muy satisfecho con el amplificador es pequeño pero los materiales son resistentes y se ve elegante Le agrege un amplificador de bajos ya que tiene su salida y ha quedado superado bien
Title: Value for money
Content: Works wel, good value for money.
