What makes you think that I am?
As things stand now I would be hard-pressed to buy another Anthem product, and that's entirely down to quality and support, rather than performance.
Oh, I read it wrong, then.
Yeah, in terms of performance, I've owned or heard just about every brand out there.
If the setup is optimal, I think all brands (Yamaha, Marantz, Denon, Anthem, Arcam, etc.) can sound equally awesome, regardless of any inaudible THD+N and SINAD numbers posted by Amir.
Thus, it comes down to quality, reliability, compatibility, price and support.
