Monster Cable ABX d vs. coat hanger.

2
I'll be posting some "vintage" coat hangers on eBay next week. $6000/pr

These particular hangers have seen only natural fibers which as you know keep the magnetic domains oriented correctly. They have never seen any "man made" fibers which disrupt these domains and cause audible effects. (I went to far as to purge all polyester from the home, in case the effect would jump from room to room and into the hangers.)

These work especially well on NS-10's

Not that I expect that guy to know what he's talking about, but electrons propagate RG-58 signal cable at .66c (not the speed of light), although. Time coherence is a silly thing to talk about when it comes to cables and audio frequencies, as the delays are typically less than 50ns at the highest frequencies. In the digital domain, this is something you could even compensate for with a FFT, and even make it dependent on your cables, as the curves are fairly well known.

The physics behind the skin effect is really cool actually. Nanowires and single/multi walled carbon nanotubes are going to change a lot of things pretty soon in the future.

Actually, now that I think about it, between some NMR oscillators and some NIM equipment, I should have enough stuff at school to measure velocity of propagation down to 1ns precision. That might be fun.

Wouldn't you need something like a 20MHz sample rate though? 40MHz?


not really. You do an effective phase shift of the sampled frequencies, meaning you change the sample values accordingly

say you're sampling a 20khz signal at 40Khz+1 (idealizing, or course)

You start sampling at the zeroes of the sine wave, and your samples slowly move up and down, seemingly to the left on the sine wave towards the peaks. An effective phase shift would have your samples starting somewhere else, say at the peaks of the sine wave. You get the same frequency shifted a quarter of a wavelength.
