This probably sounds like a dumb question. . . but, here goes. I have a Sony DVP-NS500V dvd/sacd/cd player. I presently only have a toslink optical cable providing the audio signal to my Onkyo TX-DS595 receiver. If I understand it correctly I can't get true SACD audio like this. This is probably why I have been underwhelmed by SACD. So what type of audio am I hearing when I play a sacd disc using these connections? Are there multiple audio soundtracks on sacds like DVD-A has? My thinking is I need to get 6 regular rca type patch cords and connect the 5.1 analog connections between my dvd player and receiver and go into the Onkyo's setup menu and set the cd source as analog. That way my dvd audio will still travel through the optical cable for movies and when I listen to sacd/cd's I will get the full benefit of the higher resolution. Is this correct? Thanks in advance!
