Decent enought to set up a nice sound system for working out

Of note - I have this hooked up through an Echo Dot (2nd gen); so understand I'm not comparing this to a robust audio system, just something that sounds good in the background when having people over or doing activities (like cleaning the house).

It makes my system sound great and well worth the cost

You aren't going to get amazing sound out of this but for a portable sound system, it can't be beat.

Functions great, but the LED system surrounding the volume control is pretty cheap

How cool is that?This system is somewhat more powerful and has a better frequency range than typical USB speakers, producing a decent sound with enough volume to fill my apartment living room without annoying the neighbors

Amp works perfectly with out distortion used with 80 watt 4 inch speakers for cooler system .

I can see this unit being part of a portable DIY sound system- easily

I have a decent system at my desk.

the only down side is that you can't plug in a bass, but if you have quality speakers with build in bass's then it is still a great sound system to have.

I used this to power some home audio speakers I had left over from a long dead 5.1 theater system

THD is little high at 0.10% but that's much less than the 10% THD you'll find on cheap, plastic sound systems or budget HT systems

If you have a couple of small speakers doing nothing, you can put together a decent office computer sound system with the addition of this under-ten-dollar amp and a twelve volt DC power adapter.

This amp is so small that you can even make a portable speaker system using a 12v battery pack
