Although I had watched many great reviews on this item, such things remain very subjective. I had fairly high expectations from the reviews, but still really didn't know what to expect. I was able to compare it to another popular budget brand unit in a similar price range. Although this other unit was built well and had a bunch of great features....in terms of sound and power...there was absolutely no comparison. I was amazed at the clean power and volume of the Fosi. I first ran it with Polk Mini Monitors which are small bookshelf speakers with 5.25 drivers. I just couldn't believe what I was getting out of those speakers. I then switched to a much larger set of floorstanding speakers with 8in drivers. Again... Just Blown away! This little Fosi had no problem driving them with great sounding bass, mid/high clarity and plenty of headroom. I honestly don't think I would ever have to turn this unit up beyond 12 o'clock. The Fosi is built well, the Bluetooth works great, I love the USB input, it sounds awesome and the price is more than right for what your getting. It's tiny and puts out good clean power. I wish I had some 3 way speakers with 12in drivers to test this on. In any regard, unless you need something highly specialized, this amp should make you very happy. I highly recommend this Fosi product!

Punchy and clear audio, perfect for the garage!
My old Denon receiver had a ground loop issue that I could not fix. My subwoofer would make a loud noise and I managed to get it to a lower noise but still it was not fixed. I replaced the bulky receiver with this little guy and wow am I surprised. This packs a punch! I'm powering 2 Sony bookshelf speakers and a Klipsch subwoofer in my garage. Sound is loud and clear and I have control over bass and treble. I use it via bluetooth and it works great. The volume knob feels very nice and the physical switch to Aux and BT feels solid.
