A year or so ago I reviewed an Arcam AV receiver. It was one of the best sounding pieces I have experienced. But its HDMI inputs were switching only--no audio over HDMI. That has been corrected with the new AVR600 ($4000; $4500 with Internet LAN connectivity). It will also decode all of the latest audio formats, including DTS HD Master Audio and Dolby TrueHD. It's also one of the first AVRs to feature Dolby Volume. 120 Wpc, availability expected in late November.
