Re: Vinyl records vs. Cds.

All of the source components listed in that test are universal SACD/DVD-A/CD players or SACD only players, which means they might have 1 bit sigma delta type converters for PCM CD and DVD-A playback. I'd probably have to call the companies for info on which type of DA converters they use for PCM playback, that info isn't easy to come by for all brands. The only player that is high end is the Sony, and it is an SACD/CD player, and its DA converters are 1 bit sigma delta type. 1 bit converters are used primarily for cost savings, not for high performance.

IMO great vinyl is leaps and bounds above any CDs I've heard, although some CDs are better than others. DVD-A sounds better than CD on a DVD-A/V/CD player IMO. It doesn't have SACD playback, so it may have true multibit converters.

Studios for years have recorded at 24 bit or 20 bit and dithered to 16 bit often using the Apogee UV22 process. They have found that this sounds much better than simply recording at 16 bit with no dither. But one experiment using standard consumer crap throws out all of this research and experience?
