Owning over 500 2ch SACD's, I AM interested in them. Sure, I'd prefer that ALL SACD's were 5.1. I own several mono SACD's, as well. If the music is great, I'd prefer to listen to the highest fidelity and most channels available. Fake stereo and 5.1 is of little or no interest to me.
I'd rather listen to mono transfers of Bessie Smith 78's than state of the art crap in 5.1. It's all about the music.
Well said.
