I'm thinking of buying an Atlas Opus digital cable as an upgrade over the QED Reference that I currently use to connect my Sonos ZP90 to my SuperNait. They've got them at a very good price on Futureshop so I thought I'd take a punt and see if there was any difference; even if there's not, I'm happy to sell one of the cables on ebay even if that means losing a bit overall.
Anyway, my question is that given the 'quality' of a digital coax cable and it's ability not to create jitter in the signal fed down it seems (from what I gather through reading on the subject and talking to dealers etc) to be down to the cables ability to maintain a consistent 75 ohm impedance, is it case that the impedance of the cable will vary according to what length it is, and therefore is there an optimum length for a coax cable (and will this vary by manufacturer)?
I realise that the challenge for manufacturers of such cables is more to maintain the impedance at the connection to and through the plugs, not the cable itself, which should be relatively straight forward, but I just wondered if the length of the conductor made a difference and therefore if one should go for an optimum length?
Also - any owners of the Atlas Opus care to share their opinion of it?
Cheers.
