Re: iFi Audio Accessory iPower 12V/1.8A
I've read that the way the signal is transmitted in an XLR cable helps with noise rejection resulting in a better, less noisy signal. If this is true, it still proves the basic point that cable design can influence sound quality.
Look, there is nothing different here from what I said above.
Balanced audio cables have three wires that serve as conductors--negative, positive and ground. The positive and negative wires both carry the audio signal but with opposite polarities. This means that any noise from outside interference sources will be cancelled out. Balanced cables are suitable for audio applications that require long lengths (more than 25 to 30 feet).
In other words, cable design affects sound quality.
