I have SACD, CD (1997 reissue), and vinyl (200-gram reissue) of the Dave Brubeck Quartet's "Time Out" and have listened to each quite a lot over the last couple of weeks. It's difficult for me to tell much of a difference between the SACD and CD versions, although the SACD version seems to extend a little better at the higher frequencies. What is surprising to me is how close playback quality is between the SACD and CD version. I'm generally not very impressed with the sound quality from a lot of CDs, but the CD sounds quite good in this case. On each version it is like hearing the original tapes, even picking up the occasional "clunk" sound or rustling when someone moved. The tape hiss is clearly evident on each version, which I kind of like because it shows the original recording was not tampered with. Anyone else have observations on these formats for this recording?
