Thanks guys.
Just ordered one and it should be here Wednesday. Wife's away for a long weekend next weekend so I'll be fitting the ceiling speakers while she's away. The house was pre-wired for ceiling speakers in the living room (4), dining room (2) and covered patio (2 more) so I'll be using the amp itself to drive the first 4, then power amp(s) to drive the others. Might switch that around later, drive the 4 in the living room off a modest power amp and the dining room and patio as Zones A and B, don't know yet, but that might make more sense. It's all for background music downstairs, not lights out, wife and kids away listening intently mode, so it should be good. Hopefully the network streaming is up to snuff too, otherwise I'll be plugging in a portable HDD into the USB socket. Speakers will be Yamaha NS-IC800 concentric 2-way 50 watt RMS as I happen to have 2 pairs sitting around. They can be improved upon later if necessary.
US$229, no sales tax, free shipping. What could possibly go wrong.....
