The sonic differences between the SACD Standard and KAV-280p are not subtle, the Standard is superior in every way, plus it plays SACDs. The KAV-280cd has been out of production since 2002, which is way too long by today's digital standards. The current highly acclaimed $10K Krell Evolution 505 is basically a CAST version/direct descendant of the SACD Standard, which says a lot for the Standard...(read the recent stereophile review of the 505).
