Just had a look - they only do 5 or 7 channel as far as I can see - I wanted 4 or 6 (no AV usage or surround for me, just stereo), they do look nice though 
The Arcam 4 channel ones seem to share a power supply though which is a shame, I have seen modular amps, configurable number of channels though again, really multi mono-blcok would perhaps be best, in which case, may as well go the whole hog and just buy enough mono blocks.
I speak as if I have the cash for this which I don’t at the moment, and hence am sticking to my existing Arcam stereo amps, stacked “vertically” as it were, with one stereo amp per channel, so that each bass driver gets its own power supply, works remarkably well for the outlay
