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

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!
