I'm trying to figure out whether I will be needing any analog audio interconnects. Correct me if I'm wrong but DVD and CD players these days only need to be connected by a digital coaxial or optical cable right? I have an old cd changer (nothing high end) that does not support a digital connection should I think of upgrading? Or perhaps I should look into a SACD system? If so would I then need any audio interconnects? The only place where I think I'll need any analog audio interconnect is my VCR and my current CD changer. But I will need to buy some if I want use DVD-A on the RP91 right?
