Mediocre sound quality

I had problems with this and had to return it. Biggest problem is that it would go into standby while playing music. Apart from that I think you get what you pay for here, which is mediocre build quality (speaker connectors are small and weak) and quite mediocre sound for music. Rated power seems misleading.

i am running 2 of these in bridge mode. connected to 2 Sycamore Sub-woofers and 4 2.5-inch Satellites. sound is awesome however when the volume is pushed up both amps instantly cut out. pretty embarrassing when you are trying to show off your new system and crank it up for friends and both amps go into circuit protection cut .

Works well and sounds good. Only complaint is that in the standby mode it remains rather warm for being unused. Haven't tested the power usage during standby, but I don't believe it is very low. It doesn't get too hot during usage even though I am using it at the higher end of it's capability. So very please with it overall.

Not the best option for Atmos or surrounds

I bought this wanting to power a couple of my heights, unfortunately it's not a very good option. The lack of an always on option or 12v trigger makes means the unit turns off every 5 minutes waiting for a signal before it'll turn back on. By the time it turns back on the scene has passed. I also can't get rid of the buzz. Not a ground loop but a subtle annoying buzz. I tried multiple options to clean it up but can't eliminate. I'm running 2 Monolith amps to the rest of my system with zero issues. I guess I should've spent the extra cash and added another one.

Exactly what I needed

Exactly what I needed to replace a failing 45 lb behemoth amp (overkill for my application). Connected to six-zone speaker switch and BluMe for Spotify and Pandora streaming. Price, sound quality, performance, and audio standby power all great. So far, very pleased with the product, the purchase, and Monoprice.

Great for old school whole house audio

I purchased this amp to power an existing 4 zone speaker system in a new home, connected to a 4 zone impedance matching selector switch. I’m not ready for sonos, and only need a single playback source (an old airport express). One of the speaker zones is a set of outdoor Bose speakers, which were crackling when connected to my old temporary amp, a workhorse 120watt amp from an old PA system. This 450 watt unit is perfect for my application. It provides plenty of juice for the whole house at only about 2/3 of full volume, and the auto on function is just great. The only thing I did was put a small piece of electrical tape over the red LED since it shines 24/7. The old Bose sound like new again and the whole house is rocking!
