Ok I know this sounds bad, but ive hardly ever listened to SACD. Not sure why, not trying to ignore it or anything. I listened a bit at circuit city recently and was impressed by it. They had it playing on a SONY home theatre speaker set up with a sony receiver. To me it had a very smooth and clear sound. BUT....im not so sure if that was just an effect of the little sony speakers or the SACD recording. MY question is...DO you guys hear a noticable differece with SACD??.....I mean not huge but is it noticable even if you werent aware it was a SACD?? It was mariah carey I was listening to, which I own on regular CD and havent listened to in like 3 years.
