There are great discs of all types, it all comes down to recording, mastering and production quality. I too am a huge XRCD fan of all types including as of late, the latest K2HD variants and all the XRCD24s out there. There are also outstanding RBCD examples out there from Stockfisch, Venus Records, etc...that like many of my SACDs are as close as I care to get to vinyl and very good to listen too....when you could get them, most DVDA's were also quite stunning.
As an aside, there are also lifeless, boring, poorly recorded, poorly manufactured discs of all types (and vinyl examples as well). I prefer to
stay out of the religious and other debates and chase music that I love and simply listen to it :-)
