Kal,
Are you sure Anthem has a trademark on ARC? As in Atlantic Richfield Corp as well as acoustic room correction that seems unlikely. Perhaps I haven't noticed the tm declaration next to ARC when used by Anthem. I innocently used ARC as an abbreviation for acoustic room correction, and had not intended to trespass on a trademark if such exists.
I had the impression that acoustic room correction was a feature of the chip Cary used rather than Cary's proprietary technology. Shortly after the 11a hit the market, the AVS owner's thread was filled with complaints about bogus readings from the technology. I bought my 11a at great discount after the bugs were known.
