I'm based in London UK & I'm looking to source some power amps that meet the following criteria:
RMS Power >50W/ch.
Stereo Line level input.
Must have IR volume control.

I don't need multiple source inputs as these amps will be driven from the Pre-out of a Yamaha Amp. Ideally I'm looking for a one box solution that can provide me with either 2 3 or 4 zones per amp. The purpose is to expand an existing system in the multimedia room to the Dining Room, Kitchen, Lounge and Garden. The Sonance Sonamp 1250 would have been ideal but IR volume control is vital. IR is incidentally Pronto.

CAT5 based systems (QED etc) are not an option in this case.

Thanks for your help.
