The Physics of Electricity

I know there is difference between a Sony receiver and Krell FPB amplifier

Be careful what you compare to try and draw a valid conclusion on something else. I know there is a difference between a Yugo and a Lamborghini. Means nothing about cable.

None of this "theory" matters if you can't pick out the premium cable every time with the lights out. It should be easy, since it makes an obvious difference.

This just in from Furutech,

“Alpha OCC-DUCC Speaker Bulk Cable DSS-4.1

Furutech’s α (Alpha) OCC‐DUCC is one of a select few of conductors that Furutech engineers have found to excel in sound reproduction. α (Alpha) OCC –DUCC is constructed using a combination of DUCC Ultra Crystallized High Purity Copper and Furutech’s world famous Pure Transmission α (Alpha)-OCC.  

Furutech DUCC Ultra Crystallized High Purity Copper -- supplied and regulated with strict quality control by Mitsubishi Materials Industries -- is one of the best conductors Furutech engineers have found for signal transmission. (MMI is the leading manufacturer of the highest-purity oxygen-free copper in the world) Mitsubishi process this extremely pure oxygen-free copper with new technology that optimally aligns the crystals while reducing the number of crystal-grain boundaries resulting in a tremendously efficient conductor. Straight OCC’s benefits are its larger “fibrous” crystals in which one dimension is longer than the other two so as to create as few crystal junctions as possible. Thus, OCC’s sensitivity to directionality; one path exhibits the least resistance. Furutech’s world famous Pure Transmission α-OCC is the result of further processing with the Alpha Super Cryogenic and Demagnetizing treatment. However, DUCC purity goes a significant step further. Mitsubishi Materials designed the new conductor to optimally align the copper crystal grain structure in addition to reducing crystal grain boundaries. As a result, DUCC is less sensitive to directionality than OCC.“

Gee, someone with a lot of solid engineering expertise went through a lot of high priced trouble to reduce the effect of crystal-grain boundaries. So if more is better, or in this case, less is better, would be kinda interesting to speculate what kind of benefit could occur if there were no "crystals" or "crystal junctions" at all eh. But that is the stuff of science fiction ain’t it, though it would make for a very fascinating thought experiment.

Postscript: Furutech is also the company that fills or covers the tiny physical imperfection on the surface of wire using some kind of nano tech. You know, to produce a level playing field for the current traveling on the surface. Similar to the Audioquest technique of highly polishing the wire surface, one assumes. That’s assuming current does actually travel on the surface, which is completely up for grabs. Also, the crystal grains deformed by the pulling through the die operation that lie beneath the surface - what about them? Do they sweep them under the carpet.
