I have a Pioneer D-S633A DVD player and a Kenwood KRF-X7775D a/v receiver. Both provides 5.1 audio input (receiver) and output (player). If I want to enjoy DVD audio disc, do I need to use these connectors or can I use the digital connectors to connect both devices together? Also, the DVD player is capable of 192KHz/24bit audio out, whereas the a/v receiver is 96KHz/24bit. If I want to enjoy the 192KHz/24bit output, how can I connect the player to the receiver? Any pros and cons to consider? fyi, I'm a newbie to audio/visual stuff and am here to learn.
