What is PCM (Pulse Code Modulation) as it applies to CD players & Preamp/Processors?
Are there certain cable requirements?
Are frequency/bit rates an issue for high or highest quality processing?
Thank You

In audio, digital signals and video signals are transmitted between components through a cable with 75 ohm characteristic impedance.

Digital signals in audio is not a real issue to transmit them with these cables, so don't worry as regards to your last part.
