Hi RLS,
These products are very new so we have limited reviews on them. You really have three products to choose from; the M80, M80HP, and the M100. There is a big jump in power from the M80 to the M80HP, going from 250 watts per speaker to 500 watts per speaker. The M100 is 600 watts per speaker. All of them utilize a toroidal transformer based power supply with lots of dynamic headroom. They all play loud, clean, and dynamic. We have not had a single inquiry about how to hook up the system or use the UI so that is a good sign that it is quite User Friendly. From the UI you can stream from AirPlay, Spotify Connect, Bluetooth, or UPnP and switch to the Optical and Analog inputs.
