Redbook vs. Hi-Rez

Proven: Good Old Redbook CD Sounds the Same as the Hi-Rez Formats
Incontrovertible double-blind listening tests prove that the original 16-bit/44.1-kHz CD standard yields exactly the same two-channel sound quality as the SACD and DVD-A technologies.
In the September 2007 issue of the Journal of the Audio Engineering Society (Volume 55, Number 9), two veteran audio journalists who aren’t professional engineers, E. Brad Meyer and David R. Moran, present a breakthrough paper that contradicts all previous inputs by the engineering community. They prove beyond a shadow of a doubt, with literally hundreds of double-blind listening tests at matched levels, conducted over a period of more than a year, that the two-channel analog output of a high-end SACD/DVD-A player undergoes no audible change when passed through a 16-bit/44.1-kHz A/D/A processor. That means there’s no audible difference between the original CD standard (“Red Book”) and 24-bit/192-kHz PCM or 1-bit/2.8442-MHz DSD.
Please note that this is not just a disagreement with the cloud-cuckoo-land tweako audiophiles but also with the highest engineering authorities, such as the formidable J. Robert Stuart of England’s Meridian Audio and others with similar credentials. That the Meyer-Moran tests leave no room for continued disagreements is an occasion for the most delicious Schadenfreude on the part of electronic soundalike advocates like yours truly. I stated my suspicions that SACD was no improvement over CD seven years ago, in my review of the first Sony SACD player, the SCD-1, in Issue No. 26 of The Audio Critic (downloadable from this website). I could hear no difference between the CD and SACD layers of the same disc when stopping the player and switching over, instant toggling between the two layers being impossible.
