Difference in sound between copper and silver digital cables?

Try and learn. 

Yes you are right Doug! Always outlier experiences and who knows why? System? Ears? Break in? Bad pizza? 

@williewonka Steve: within the parameters of (the "experiment" / components / systems) you tested them, correct? Thanks.

With this design using a silver conductor seemed to offer no advantage.

Do you mean after they’re broken in? Before or after cryo? Yes I know what you’re thinking, “Are you hot dogging me?”

The geometry of the cables is an advance Helix design, so that probably made a significant contribution to the performance of the cable.

Steve, I always have great respect for the very extensive work you’ve done with cables over the years. But in this case I’m wondering how or if you might have established what IMO is the requisite 75 ohm "characteristic impedance" for an unbalanced digital cable, using the helix geometry you have used for your analog interconnects.

Also, IMO, if the characteristic impedance of the cable was not known to be an accurately controlled 75 ohms the sonic consequences of the resulting mismatch to the impedances of the components being connected figure to be even more dependent than usual on the designs of those specific components, and probably also on the length of the particular cable. Making the sonic effects of the particular cable pretty much random and unpredictable among different digital applications, IMO.
