I have a Denon 1802 amp and a Hitachi 53" TV. I ran RCA cables from the TV to the amp so I could control amp volume with TV volume via the TV remote. Yesterday I had digital cable installed in my house, and the new cable box had RCA outs on the box that were intended to connect to the amp. So, I disconnected the cables from TV to amp, and installed a pair of cables from the box to the amp. When I did that I lost the ability to control amp volume and TV volume simultaneously with the cable remote. I could hit the "audio" button the the remote to control the amp, but I really don't want to do that. My question: am I losing sound quality taking the audio signal from the TV? Would I experience better sound feeding the audio signal directly from the cable box to the amp?
