Playing SACD on a Non-SACD Player

One still gets the benefits from DSD when playing an SACD disc back in a redbook machine.

The main problem with standard PCM technology is that it requires both steep (brick wall) filters to block frequencies above 20kHz (specifically at 22.05kHz) which is difficult to build. It also requires the addition of re-quantization noise for its decimation (down-sampling) digital filters and interpolation (up-sampling) digital filters. These problems limit the actual fidelity of the reproduced audio.

DSD Downconversion

Using single stage FIR digital filtering and noise shaping, 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.

Duh! I never said they could. What I am trying to get through to you is that DSD mastered discs are more easily mixed down to 16 bit thus gaining better sound quality than discs originally mastered using PCM. If one can believe a power cord can make a difference in sound quality(not you in particular)then they might think that better mastering should also.

I agree my first response was not stated as well as it should have been.
