| Re: 1930 sa-cd connection
OK! I may be a bit sketchy here in my knowledge, but I think Sony were the original developers/owners of SACD which was an attempt to prevent "CD" copying. There are no commercial products out there that will copy or duplicate an SACD "CD". To prevent people from intercepting the digital stream and ripping the audio out, Sony provided some form of encryption which either the SACD player had on board, or if it passed it to an external decoder over a secure connection. For Sony products it may be that they could guarantee this delivery mechanism through the two phonos route.
On the later Denon amps (and after a long protracted battle to get SACD licensed over the D-Link) are able to connect to the SACD player and get digitally connected for decoding by the amp. However, for those people without this connection the 5.1 analogue output was created. The SACD is decoded into multi-channel analogue output for connecting to amps without a proprietary license/encryption for SACD.
I think!
