It's funny, I have been on the Hi-Rez bandwagon now for about 2 solid years. I have amassed about 150 SACD's and a handful of other Hi-Rez format discs. I can even be found at several points on this very thread saying GO! SACD GO! -- I think I am going to get off this ride though -- the vast majority of the SACD's I purchased were hybrids, and new music to me. But lately, I have made some comparisons between recently remastered redbook CD's and their SACD counterparts. I tell you, it is a really close call -- the quality of recent redbook remasters on decent equipmetn is so close to SACD that I would rather buy the redbook remaster because it is easier to find, costs a lot less, and sounds just as good.
Now, pure DSD recordings are incredible, and SACD's on a half way decent machine get you a level of sonic performance you would have to spend a lot more on a dedicated redbook CDP to acheive -- but, I think, if you can afford a pretty nice dedicated redbook CDP, you will get better quality from redbook CD's comparable to SACD. I think that is the direction I am going.
