No the amps are not glued to the back. The BryFi is a complete redesign with a separate stereo amp a Raspberry Pi computer and a pair of Mini A speakers.
Since the unit is quite large and wifi hot spot capable, and there's a funny 'computer' inside, how about adding a simple, dedicated UI / OS and HDD bay so it can be used as a music library / server for existing audio systems?
BryFi can stay in the bedroom but it can also become an active component in the main system simply by adding a 'BryFi companion' --- a dedicated wifi receiver for Bryston DAC / digital players via USB connection. So digital lovers can ditch their complicated iMac, NAS or whatever and use the cool, simple BryFi + iPad combo instead.
It'll be even more appealing if it's compatible with other brands' DACs, or anything with a USB slot, such as a TV, computer , playstation .... And truly become 'great music anywhere, everywhere.'
A wireless , good sounding system in a small package is nice, but to become great it must do more, and more versatile . And don't forget the lamp.
