One thought that adds to my belief that it wasn't Anthem is this: ARC is completely different than Audyssey. So, could pre/pros (or AVRs) that support one or the other actually be manufactured on the same assembly line?

If it's the same platform, I doubt it. Kind of like (in the old days), you trying to load Windows onto a PowerMac. Can't do it. The hardware is so different, the only way was to emulate the foreign OS. Can't run it directly. So I believe that it's not even possible for the same platform to run ARC and Audyssey.

If it's the same manufacturing line, but completely different parts, then obviously it's possible. But that's not the gist I got from Outlaw's email.

So I think NAD is the most likely candidate by far.

I suppose we'll know who it might be by whoever introduces an XT32 SSP in the next 3 to 6 months !!
