I would like to believe Synfreak re DVD-A's having the actual hi-res stereo tracks on the DVD-A. But, why da hell are these outfits using DVD-A's as there source? Are these legitimate companies? What kind of licensing agreement exists between them and the music producers? It just sounds a but strange to me.
In response to those who imply that such mix downs may be acceptable--they are are most certainly not! I don't need to tell you folks that true multi-channel recording are quite rare, usually found in the classical orchestral arena and specialty recording arrangements. Most all multi-channel stuff is manufactured in the studio. Why would I want a mix based on this!
