What better the Krell KPS 28C??

I have had the KPS28C in my system with a KCT and FPB200c for over a year now and I am very pleased. Previous CD player was a KRELL KAV250cd which was pretty good in its own right. I haven't had the chance to compare too many other CD players but it beats the pants off SACD on my SONY DVPNS999ES (but perhaps that is an unfair comparison). Though skeptical at first I found that the CAST system really does offer an improvement over the balanced and single ended options.
