1-bit DSD can be down-converted into standard 24, 20 or even 16-bit PCM audio for CD distribution while still retaining the maximum possible audio quality. The system's 2.8224 MHz sampling rate is specifically designed for high precision down-conversion to all current PCM sampling rates using simple integer multiplies and divides.
Rwwear, despite this statement, repeated from your earlier post, redbook-only players will not play SACD discs. If you can point us in the direction of a CD-only player that can play SACD discs, please do so. I think we would all like to know about it.
The answer to Lkissinger's original question:
Is there any benefit at all to playing a SACD on a normal red book player?
...is that there is no benefit, since normal redbook players can not read SACD discs.
