  • Blown Away!
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! ... show more

  • Surprisingly capable small amp
For starters, this is only after a couple hours of continuous usage, so things may change. For now, I'm very happy with this thing. I ordered it and some Micca RB42s and snagged some Memphis Audio speaker wire from a local store. So this thing paired instantly to both of my phones and my tablet, and the rca input connected to my record player was problem free. Front controls feel nice and have notches as you turn them. Buttery smooth. I haven't tested the sub output yet as j don't own a sub, but that should also work just fine with the right sub. Construction feels nice and heat management seems fine after these couple of hours so far. As for sound quality, I'm new to amps and passive speakers, but this is pushing the Micca's really well and everything sounds wonderful. No noticeable distortion or anything but I haven't cranked it yet out of respect for the roommate. Maybe when he's gone for a day... Chassis feels solid and durable, but not sure if it can be easily disassembled for people who want to tinker or change op amps. It's small size really belies a lot of clean power here and I'm very happy. My only grope so far is for when using speaker wire instead of banana plugs, the holes to put the wire through at the back of the amp are very small, only a bit larger than the 16 gauge wire I'm using. Won't be an issue if you're using banana plugs, but do keep that in mind if you're using just the wire. So far I'm super happy with this little thing. Very impressive. ... show more

  • Great Amplifier, but adjusting settings can change quality drastically!!
So to preface, I am not a speaker audiophile, but I do think I can hear differences at most quality levels of speakers. My current setup is meant to get the best bang for my buck ~ $300, with 2 T15 Polk passive speakers + 1 PSW10 Polk Powered Subwoofer + Fosi Amp BL20C I was originally having an issue with stronger bass hitting songs with soft entries of bass and vocals. It required turning my devices audio output to max AND turning down the amp's dials for treble and bass. The amplifier for some reason (I'm not a speaker expert) would not allow for strong bass hits and entries of sound if the audio input wasn't maxed and the bass knob wasn't turned all the way down. I wish the amplifier would allow me to adjust treble and bass without compromising on its performance. Other than that, this amplifier does the job solidly, Bluetooth is strong and reliable so far, audio seems well balanced from my classical music to my rap beats, but requires tinkering on my devices output rather than the amplifier's settings. I highly recommend my setup as long as you don't expect to play around with bass and treble on your amplifier!!! ... show more

  • As advertised! Better than I hoped for! Wow!
I don’t wrote many reviews, and was looking to replace a gigantic 25 year old 5.1 JVC Integrated Amp/AV stereo I use in the garage as a 2.1 stereo for streaming along with a cheap bluetooth receiver. Old and dusty and starting to be a little gitchy with volume and subwoofer issues but plenty of power for to fill the garage with sound. I looked around a lot and must have put dozens of items in my cart and taken them out over the last year, including this one. Made on offer for something else on a different place and got countered so i had 48 hours to accept. It was twice the price of this. Bought this on a whim with next day delivery and a 5% discount, thinking i could try this if i didn’t like iti could still accept the other deal. Tried it out last night and wow! Very loud, excellent controls, and oh so small! Not audiophile, but very clean sounding, bright mids and hoghs and loud boomy base from my old powered kilpsch 10 inch sub. Makes me thing the glitches on my old receiver included the subwoofer out port! Perfect for my garage. Id say a little light on the mid bass, but that could be my setup with bookshelf speakers (polk t15, about 10 years old). Very satisfied! Not sure about longevity, but no reason to worry, just haven’t had them long. Everything seems like a quality build, if a little basic. Streams bluetooth from my phone well. ... show more

  • Phenomenal
Such a great surprise for the money. I’m running 2 pairs of speakers, the unit is in my garage and subject to -30F temps in the winter and has never failed, Bluetooth works great, sound is great. Can’t imagine why anyone would spend more for an amp.
