Beautiful sounding pint sized power amplifier.
I have to admit that I was skeptical about this little amplifier on sound and power and let me tell you, this amplifier has a excellent sound quality, just as good as my big amplifiers in my floormodel stereo system, and this little amplifier is capable to drive my podium pro dpi/800c passive speakers which are rated for 10 to 300 watts of power and this amplifier powers these speakers with no distortion at all and gets really loud as well. It really made my speakers sound better than I have ever heard them before, with good punchy bass and crisp high range and fuller mid ranges, it makes my two way speakers sound like three way speakers and also sound like top notch audiophile grade home audio speakers, and these are 8 inch pa dj speakers. Simple to set up and use, just connect the speaker wires, + to +, - to-, the audio source via RCA cable, plug the power supply into the power input on the amp, and power cord into the power supply, turn it on, adjust the treble and bass where you like it, adjust your volume to any level and you are up and running. This is a excellent investment for my small stereo, and I was just blown away by this little fart of a amplifier, buy it and you will be rewarded with audiophile grade sound with a good set of speakers, mine are pa speakers, audiophile grade speakers will most likely sound alot better. One heck of a sounding and powerful little power amplifier for sure.

Compact, powerful, and perfect!
Bought this to power an old pair of passive speakers and it’s been great. Setup was simple, it’s surprisingly powerful for its size, and the sound is clean. What impressed me most is how quiet it is. No hiss, hum, or other background noise through the speakers when nothing’s playing, which I wasn’t expecting from an amp at this price. The bass and treble controls are useful, and overall it feels like really good value for money. I love how it’s so compact!

Small and compact but powerful!
I was looking for a small unit to replace an LG bookshelf stereo I was using with a pair of paradigm atom 7 bookshelf speakers. I found this fosi amp with 1 analog in and though I'd give it a try. Upon hookup and having my first listen I was totally blown away at the sound. The LG system I was using before pushed 550 watts before but that system had 2 bookshelves and a sub that went with it and I never got the sound out of my paradigms with that like I do now with this fosi amp. Clean and clear sound is how I'd describe my sound now with this fosi amp. Call me impressed fosi but this is incredible for such a compact amp. I will be ordering again if I need an amp for a garage setup or something. If any of you are in need of a small amp for a pair of bookshelves with only one source needed give this fosi a serious look. IF this thing last it will be a jewl in the audio world. Thanks again fosi for a great product. *UPDATE* I was so impressed with this amp powering my paradigm bookshelf speakers that I had to buy another. I have definitive 9060 towers in a stereo setup and I use an emotiva pre amp with a crown xls 1002 amp. The crown puts out 215 watts into 8ohm. I wanted to see how this fosi amp worked with my towers so I hooked it up and hade a listen. Wow is all I can say. I love the fact that this amp has tone controls as well. This amp drives my towers no problem so far and I am impressed I can run them off this amp. If this thing lasts I will be very happy... It has a great warranty but I did buy the 4 year extended. Thanks again Fosi. *Update 2* I wanted to say when I turn my amp off via the front switch the red light goes off. This is probably due to this updated version as a lot of reviews seem to be for the previous version and or the Bluetooth enabled version. I wanted to point this out for others. This amp is running like a champ still powering my towers and I'm loving the clean and clear sound I'm getting out of my deftech 9060 towers. It's like I have new speakers... Lol... My other fosi amp will be here tomorrow for my bookshelves. I'm just giddy that's this amp does this well compared to what I've used before.... Awesome product... Just want it to last but so far has ran very cool and quiet... I Love these little but powerful amps... 😊
