azanon,

does your receiver have 5.1 analog inputs and apply bass management to them? Do you have six rca cables to hook up the player? It is an additional expense people overlook. Hooked up properly and with good bass management, DVD-A's and SACD definitely sound better than DD5.1 and DTS.

Anybody know what the difference is between the 536 and 578 besides 42?
