OSD Audio OSD XMP100 GEN2 2X 100W Class D High Power Stereo Amplifier, Bass and Treble Control 90 dB SNR, Wireless BT

I'm using this amp with a Denon PMA-600NE. It's only 30 watt/channel. This OSD amp does what its suppose to with increasing the amount of power, but it also adds a nice touch by letting me increase the bass. You can also adjust the amount of treble. I'm kinda a bass head so I like alot of bass. What I'm listening to is from the early 80's and the music back then all had a good bit of bass. Anyway, it's 6am and I got the house rockin'!!! Lots of bass and volume. It's rated at 150 watt per channel at 2 channels, but I have 4 speakers connected so I'm not sure but I think it reduces the watt/channel.If you need an inexpensive amp for your stereo, buy it you won't be sorry. I now have 3 OSD amp. Two of this model. It is the amp sitting on top of another amp I was using. It has 2 red Lights and a green light on the left side. Two knobs on the right side.

Thing slaps as far as fast food dining room speakers go, just make sure to turn the bass to +5 with the little knob on the back

Sound quality is fantastic, especially considering the price. Certainly exceeds my expectations.

This unit came packaged very well and seems to be made at a decent quality. I only wish it had a digital screen. Everything functions good as it should. All knobs feel smooth and I haven’t had any issues with it after installing speakers. The unit gets a little warm but most audio equipment gets a little heat after running it. Nothing to worry about. Overall, I’d recommend it for more simple installs. This worked great in shop with a few speakers.

This two zone stereo amplifier sounds great. It is very simple to set up, and very simple to control via the front panel. There are recessed base in trouble controls on the rear so that you can set it and not worry about anyone fiddling with it or accidentally bumping it. This amp also comes with rack ears for mounting it in a standard 19 inch rack. I will actually be using this in my studio in order to check my mixes on standard two channel and four channel stereo speakers, specifically on 6 1/2 inch and 6 x 9“ speakers, in addition to my 2.1 and 5.1 checks. This unit would be perfect for a house or business where two rooms/zones are desired to have audio.

I purchased this from another retailer, but wanted to add a review that was useful for others looking for a recommendation. I was looking for a higher wpc amp for a whole house audio application, and this one it a great fit and value for that. I have 5-pairs of speakers connected through a speaker selector and am using a WiiM Pro Plus streaming device as the source. There is more than enough power with the volume around 40%, and the sound from this setup is crisp and detailed. Speakers vary from Yamaha/Polk in-walls, OSD AP640s, and Klipsh AW-650s. The WiiM is connected to the primary source, and the auto-sense feature works well for sleep mode with minimal wake-up time when the music starts. I also have the line-out connected to a separate pair of powered speakers in my office which is working well. I don't plan to use the Bluetooth feature, but good to know it's a potential in the future. One quibble would be the screw-on speaker wire connectors vs. having banana plugs, but they are easily accessible and work fine. Overall I would highly recommend!
