Ok, I've got a Multi-Channel receiver (Pioneer VSX-C501), and a Multi-Channel DVD player (Pioneer 565). At the moment, they're connected using an optical cable, for the simple reason that I don't own any DVD-A's or SACD's. Being a bit of a newbie to Multi-Channel, I have a couple of questions. 1 - If I hook up all the multi-channel connections, will this carry Dolby Digital and DTS OK, or can you only do that through a digital out ? 2 - If the answer to the above is "yes", do decent cables make a big difference ? Its only RCA to RCA connections, and I've got plenty of spare cheap ones lying around...... 3 - Will it sound better than just using an optical lead ? Cheers guys...... Ian.
