Before judging the differences between analog and digital,make sure to give the DSD of SACD's a listen.It is a different technology than the PCM used in standard cd's and DVD Audio discs.If your SACD player AND receiver do not have either Firewire (aka I Link,I EEE 1394) which is rare or HDMI version 1.2a or higher connections,you are not listening to the DSD as it is downconverted to PCM over any other connection set up.Even some receivers with HDMI 1.2a or higher cannot decode DSD.
