Okay, so can someone clarify the names and types of cable I'm using for my digital connections? The Chord Signature running from my CDP to DAC? Is that a digital or co-axial or are they the same thing? The two that run from PS3 to DAC , and Airport Express to DAC? They're optical, yes? And spdif? Is that the same as a co-axial or what? Yours, slightly confused.
