In my opinion SACD (hybrid) is going to be around for awhile and if a manufacturer wants to compete in the digital arena they need to offer it on their players; which is probably the case with Wadia. It has been my experience that SACD sounds superior to redbook in the majority of CD's that I own. And if available I always purchase the hybrid disc over the redbook only counterpart. As far as XRCD they are far to expensive to even consider me buying them as well as to limited in the selection available. And with HDCD not enough players available to play the format and limited material avaialability. I would never consider purchasing a player that could not play SACD's. But again this my preference and others have theirs.
