SACD anyone???

I put this under music because;great sounding sacd is my goal.Before I get to far,I just bought my first XRCD and it blows me away. ---Over at avsforum they have what they call a tier system for the new format discs. This is based on pic.quality. So, of the 3 sacds I own none sound as good as the one xrcd.
I went thrugh all 53 pages at Music Direct and only found one item to buy.
I noticed a pretty skimpy representation in the C&W arena. Are they stereotyping c&w fans??? It would seem so. All I saw was some4/5 Johnny Cash, 2 Allison Krous;not much more Further,5.1 sacd isn't for me. Then we have 3.0 or even 4.0
So, are there sacds that sound better than other sacds??
Background: I have a sacd changer I have owned for 2 years. I also own a dvd-a changer in another system.I never bought either software---till I bought AA Prestige se. THAT set me off on a journey to see,7 years later what these new formats have to offer.
My tastes would be classical first,C&W, then 70's. Back a few years ago Sat's Music Choice had a Dixieland station. That and some good big-band stuff. The sacd's I own 2 Bob Dillon--(So,So,) a Classical 3.0 I bought by mistake. I ordered Dvorak/Szell's Slavonic Dances. Do some labels sound better??
