If you use pressure (tightness) like a speaker terminal you can screw tight you will increase the area of electron flow by mashing the 2 metals together. Imagine 2 sheets of sandpaper lying face to face on top of each other. Press down on one and its harder to move because the roughness or grit becomes more interlocked. Now think of an RCA jack and the way it contacts a jack. Better than pressure would be soldering.
You can argue your mega priced cables but the ones that let the most electrons through would seem to me to be the better ones. Maybe that's a measurement we need.....take care...Mark Korda
Hello Mark Korda
your name sounds real familiar. surly your right, contact integrity is a huge issue BUT
I have 2 cardas power cords, the cheap one (180.00?) truly completes the system on my amp, only a worm could not hear the smoothed roughness removed, but at my other house it was zero improvement or need,
I even complained about this dam power cord here at circles a few years ago, but i woefully need it in this new house
but this is the wire that had the loose (amp end) connection Cardas replaced for free, I never sent it in, long story, but mine is not gonna move around any,*
it has a loose connection but incredible difference in smooth.
theres a treatment in that cord, as cardas always does, he's changed something.
