never heard the 20 bit, but the 24--in a word--and I mean this technically--glorious! Rich, full, and liquid. Matbe the most musical player I've ever heard. If all the other stuff out there seems analytical and cold, then this is the baby for you. By the way--I don't mean it does do a superb job on detail. Very deep soundstage. I can't afford one and this truly sucks!
