The Sonos Amp is a wonderfully minimalist amplifier, and even to the extent that you can locate it out of sight. However, connectivity is pretty basic. With digital sources you can stream music, and you can watch TV via the hdmi connection. If you want to play CD/DVD/BD the best way to do this is to connect the disc player to the TV. However, this requires the TV to be on - not a problem for watching video, but a bit much for playing CDs. For that, you can use the analogue input, but it measures less than perfectly. In short, I think it is not a convenenient amplifier if playing CDs is important to you. However, if you have largely moved to the modern world I think it is great.
