Fosi Audio TB10D TPA3255 Power Amplifier 300Wx2 HiFi Digital Stereo Audio Amp 2.0 Channel Amplifier

Disclaimer: I know almost nothing about speakers or amps. I've been doing some composing, and all my mixing has been done with headphones, which meant I wasn't mixing well for multiple scenarios. My bro-in-law offered me some Yamaha NS10s he wasn't using anymore, and I gladly accepted them, not totally realizing I'd need an amp to power them and interface with my computer. A bit of research had me eyeing $800+ amps, and my new-to-me monitors began collecting dust stacked in the corner for a few months before I stumbled upon a forum thread suggesting Class D amps like this one (a recommendation that stirred up much controversy on the forum, as I recall).With some skepticism, I gave this a try, wondering how a $70 thing could solve a problem that my research suggested would cost hundreds or even thousands of dollars.For my use case, this works great. My computer, scoring software, and DAW recognized the unit as an audio output option the moment I flipped on the power switch. It doesn't offer much in the way of EQ controls — just volume, bass, and treble — but for my use case, that's perfect.I also REALLY appreciate that the description is so clear — it explains that the unit can handle two channels, each 150W at 8 Ohms (so if I blow out my monitors, it's not going to be because they didn't give me exactly the info I needed to make a better decision... I hope I read the NS10M specs correctly!).Build quality is surprisingly good for cost. The power switch has a nice resistance and feels very solid, knobs rotate with some nice balance of glide vs. resistance as well. The switch and simple knob layout makes it easy to use by feel, since the unit is hidden under my desk. It also provides a few interface types (RCA and banana plugs style), although I wish it had an aux jack for my headphones and a way to toggle between output destinations mechanically vs. having to disrupt software workflows to go between speakers and headphones (and that would make for 1 wire out of my laptop vs. 2, which cuts down on clutter), but can't get everything you want at this price point, I suppose!It's routed through my thunderbolt dock, so when I switch the dock from my work laptop to my computer laptop and forgot to switch the unit off, there's a mildly alarming hum, but it's probably to be expected and a good reminder to turn off the unit when I'm not using it anyway.Definitely recommend as long as you check the specs on your speakers and also don't need it to have fancy bells and whistles for your use case.

Love the sound of this, was very impressed when I first listened to it. Have gotten other small amps like this in this price range and none of them have impressed me the way this one did.

This would be a great amplifier if the left channel audio did not cut out routinely. It is NOT a cable connection issue because the fix is to switch the unit off and then back on. The quick power cycle brings the audio back every time. Too bad.

I purchased this to test out a set of passive bookshelf speakers I got. Really impressed with them. Easy to setup. A great starter amp for someone looking to power a couple of speakers. Remember that your audio is only as good as every step in the chain. If you have bad inputs you will get bad outputs. When I hooked these up to my PC with a quality DAC everything sounded amazing. When I used my low end record player things were mushy. Not the amplifier's fault at all. The one thing that would have pushed this to 5 stars is if they had include a composite cable. With everything running off of HDMI now a lot of people don't have a composite cable lying around waiting to be repurposed.

I am pretty impressed with this unit over all for the price. They push my Jamo 803's with no issues for gaming and music. I am not a audiophile by any means but I do not notice any background hum or issues like that. In my use case the unit stays cool to the touch when using.
