Apologies for my ignorance, as I am a newbie into HiFi. I have a Yamaha RX-V2500 amplifier and I just bought today NAD c542 CD player for listening to stereo music on CDs only. May I seek your advice on what interconnect should I use for listening to 2-channel music to get the best out of my system. My questions are : 1. Should I use Analog or Digital Coaxial interconnect ? Which will produce better sound ? Regarding digital output, the NAD C542 manual says that "The serial data output is taken after the error correction but before the digital-to-analogue conversion and filtering". If I go with digital out, am I missing on the sound quality ? 2. From this forum I came to know that the above decision will determine which DAC will be used. In my case, how can I know which DAC is better - NAD c542 or Yamaha RX-v2500 ? Any opinions here ? 3. If Digital Coaxial is better, the salesman recommended Van Den Hul DigiCoupler 75. Is there any better recommendation. Please advise as I am lost with all the technicalities.
