There are fairly large differences in conductivity between conventional and UPOCC wire. UPOCC copper is generally about 3% more conductive than standard ETP copper that is the defined standard at 100% and UPOCC silver is about 2% more conductive than 4N silver. UPOCC silver is a whopping 8% more conductive than ETP copper.
But what matters is the sound and UPOCC metals add less warmth (copper) or harshness (silver) and allow more fine detail to come through. For IC cables this makes a huge difference and you'll never get great soundstaging with copper IC cables, and you'll never hear fine details in acoustic instruments and voices.
FWIW, Delphi Aerospace uses UPOCC copper in a litz arrangement for wiring spacecraft.
Also, many people give me near-identical feedback on the sound of my cables, so either they sound the same to people or there are mass delusions going on.
But whatever, some people just can't hear subtle differences... that's fine. When I was a kid selling electronics it became very obvious to me there is a very wide range of hearing acuity. Some folks can barely hear differences between SPEAKERS! What sucks is the people who can't hear differences insisting there are none. Most of the time they are completely ignorant about cable design and think LCR is all there is to it. Sorry, but that's wrong. There are other factors, many of which become critical for high frequency cables, and these factors do affect audio frequencies, although much more subtly vs higher frequencies. Basically, what makes a good cable for high frequencies also works well for audio, but of course there's also much more to it...
Also, it's interesting to me that people that think there are no differences NEVER take me up on offers to try my cables. Never, not once... this is more like dogma or religion. People with true curiosity and an open mind might actually experiment, but those who don't believe are, imo, the least scientific-minded people ever.
Anyway, I'm kinda over arguing about it on the internet.. you can comment on what I said but don't expect a response.
