Los diferentes masters de DSOTM

En este foro useño, hay abundante información sobre los diferentes masters del mítico DARK SIDE OF THE MOON. Me lo he leido todo de arriba a abajo y un aprimera conclusión es que en este foro sabemos mucho más que ellos de SACDS, bits, niveles, etc. Hay muchos que se sorprenden, a estas alturas de que discos extraídos del mismo master suenen distinto, sin percartarse de los diferentes niveles de grabación (existencia o no de pre-enfasis) y lo asocian al sustrato, etc.

Os copio la información más relevante que he extraido del mismo:

The SACD release actually has three different masterings on it. I listed it as a single mastering (#10) in my Dark Side document since I am unable to read peak levels for anything other than standard layers on CDs.

But in reality, the SACD has on it:

1) SACD 5.1 remix
2) SACD stereo
3) Standard (Redbook) stereo

The 5.1 mix is terriffic, IMO. And made directly from the multi-track master tape.

The SACD stereo is also really good. Keep in mind that you can only play/hear this on an SACD player. Made directly from the master (stereo mixdown) tape.

The standard stereo layer of the SACD is the only one you will hear if you put the SACD into any regular (non-SACD) CD player. This is the one that has received negative comments from some people on this board.

I believe that what the standard stereo layer lacks is due to the pressing/manufacturing, not the mastering. Perhaps in order to get all three on a single disk, something was sacrificed. Just a thought...
