I always knew the reason for SACD and DVD-A always staying a niche market. It is exactly this. And here we have the prove finally.
The most common reason for poor sounding recordings (including vinyl and tape) are poor mixing and/or mastering. In fact, when properly done and the equipment is in a mint condition, there is little difference even between tape, vinyl and CD.
Yet, we have many cases where either the CD or the vinyl has far superior sound, due to better mastering. Cassette tapes can be of really good quality as well when done with Dolby S.
The only real advantage of those new media is 5.1 sound. But then again, as a regular DVD-Video can handle it already, there is no need for another standard.
And for those producers don't even care making use of the potential a Red Book CD Audio has to offer (see my signature), there is really no need for a "better" format.
