Compatibility question regarding a Chord 2Qute and a PS Audio Perfectwave Transport

Well, I’m not sure what to suggest regarding that cable. On the one hand I would of course consider a recommendation provided by PS Audio for a cable to be used with one of their products to be extremely persuasive. On the other hand I don’t see how a cable employing that kind of construction can maintain an accurate 75 ohm impedance, at frequencies extending far into the MHz (radio frequency) region (those frequencies being very important in the transmission of digital audio signals), and without significant variations in the impedance along its length.  Not to mention the lack of shielding.

BTW, I note that Anti-Cables only offers their digital interconnects in a length of 1.5 meters, and near the bottom of their web pages on those cables they reference the paper by Steve Nugent of Empirical Audio which explains the rationale for that length. That length should be viewed, IMO, as providing the best odds of being optimal (unless an extremely short length is practicable, such as 6 or 8 inches or so), but both technical considerations and anecdotal reports that can be found here and elsewhere suggest that it will not always be optimal. As I mentioned earlier what length will be optimal depends on signal risetimes and falltimes (the amount of time it takes for the signal to transition between its lower and higher voltage states, and vice versa), which is almost never specified, and several other component and cable dependent variables.

Good luck. Regards,

andrew, much of my knowledge of digital cables was learned from Almarg and others on the forum. My background is in the analogue world of broadcast and studio recording. So digital came later.

It is a trial and error process, so buy from companies that offer a return policy.
I agree with Al's statement regarding the construction of Anticables. We need to hear from a user's experience with them.  
My first coax cable was a 1.5m Mogami for $30, not great, but it got my kit up and running. 

A good explanation of spdif cable...
