Hi! I was reading another thread, and I realized about something I never questioned myself... I have a Yamaha RX-V530 amp, and a Sony cdp-530 player. I connect both via analog, so the cd player is doing the conversion... Now, since electronics evolve so fast, and the cd player is "much older" (in the development sense) than the amp, maybe the amp has better d/a converter, so I should better use the optic output to connect them... Opinions? Thanks!
