Picked up a blu ray player over the weekend which has the 7.1 analog audio outputs. Since my receiver is a few years old without HDMI and now is not the right time to upgrade receivers setting it up analog to get Dobly True HD and DTS MA is my only option right now. I'll keep the optical cable on for the regular DTS and DD audio, but for the HD audio I figure it's how I'll get it since my receiver has 6 channel input jacks. Now my question is do I need to buy 6 individual coax cables, or will some of my older cables that were composite and 2 channel mono cables? I know the cables I have carry analog and not digital signals like the coax cable may but the outputs are analog so I don't know. Thanks for the help guys.
