I never came across it before. My favorite format DVD Audio has bit the dust. What I have found for quality recordings is not the "final" format. It is the format it was recorded in that sounds the best to me. I believe the LP/CD debate is flawed as most material in CD was remastered from analog. In that case I listen to the LP if available. With DSD the same must be recorded in DSD.
Years ago we went to a recording studio in Trenton NJ and the digital feed sounded better than the analog feed. Our club was stunned by that.
