that a well made sacd player will sound excellent on sacd and excellent on redbook by virtue of its excellent construction and attention to detail -- So, a Sony SACD 1 should sound better then a SCD333ES on redbook and SACD. Better quality, better sound, right?
I understand that there are exceptions to every rule, and comparing different technologies gets us into the apples and oranges thing. My specific point is, that we should not expect a revolution out of a $500 player just because its SACD. It takes a lot (parts, engineering, good recordings, etc.) to make good music. That's my two cents....
