The Onkyo Integra DPC 8.5 is a 6 disc changer universal player that will decode SACD. It was about $700. The DPC 8.5 has a button to bypass all video circuitry, and this improves sonic detail. It's not bad, but (from what I've been told) would be unlikely to match the sonics of a truly high end single disc player. As far as I have been able to tell, there simply are no ultra high end multi-disc players. However, the sound of this particular player improves GREATLY when it's used with the DAC I have (which is a Dodson 217 Mark II D with the 218-like upgrade, which has also been cryoed, but it was excellent before the cryo as well).
