My Squeezebox Touch came in this week and I paired it with an Icon
Amp at 48W.

They are a perfect little pair. The Icon is the same width as the Touch and acts as a small platform. Sounds great!

Regarding the touch, it's very very nice. The UI is intuitive and responsive. Sound is great. Sync's perfectly with my three other Squeezebox Booms.

I hope that Logitech makes a version of this that is just a battery
powered remote. That would be a very nice replacement for the duet. Maybe they could put a small amp in the duet receiver?

It would be especially nice if the Touch Remote could replace the Harmony remotes. Upgrade the IR Range Extender with Wi-Fi and now the Touch Remote could control IR and Wi-Fi devices.

P.S. no relationship with Icon or Logitech.
