If you're referring to the Japan SHM-SACD, IMHO there are CD's of it that sound better.
When I first bought the SHM-SACD of Aja I was a little disappointed...I expected too much...I've had 2 other CD versions of aja that had slightly better DNR numbers but didn't sound as "clean" as the SACD did...I think this disc gets criticized because of it's price...it was $60 when I purchased it...I've grown to love this disc...and the other thing having to do with expectations is people expected the type of sound quality that SD is famous for in their multi channel releases...which is a little unfair...
