I have an Arcam AVR 11 I use with their PA 720 power amp, bi-amping ATC SCM19 speakers. I usually use the front 2 speakers only for music but with the additional channels I power a 9.1 HT system for TV and movies.
I like the sound - clean, accurate and musical.
I got the electronics from Crutchfield, who offer great service, and sometimes have returned items available at a discount
Arcam are owned by Harman Kardon who are owned by Samsung. Neverthes you can get through to their support team and they do answer questions. Most of the design engineers from the A&R Cambridge days are long gone though, I was told.
