Difference in sound between copper and silver digital cables?

It’s been a while and I just re-read this thread, probably dead now.
However I have recently done some wiring in my amplifier and found this thread about helix wire geometry. Yes, I used the helix wire geometry with Cat 5E wire.

I used to make Curious Cables in Australia, and without giving too much away (or maybe I am?) annealed silver in PTFE tubing with quite a bit of space for air, and USAF wire used in fighter planes was purchased through a wire broker. There is a woven pair of grounds that go around the signal wires, not dissimilar to the same concept as the helix.

There may be others that can beat Curious Cables USB, but are there any that can for the price?

Silver offers much more crispness and better clarity especially copper by its self, because most manufacturers use silver plated copper, some do all pure silver wire cables. However silver will seem to promote midrange and high frequency with much more ease, and be tighter in bass but definitely not lacking in low frequency production.

 The only truth in this is the fact that silver has a bit of "clarity" that appeals to midfi-owners. This is because silver, unlike copper, has a decreasing resistance to higher frequencies.
