I too think frequency response is one to eliminate. But how about
intermodulation, to take another possibility?
For example, the "thousands of millivolt diodes in series" argument is
used about (a) poly-crystalline copper (as opposed to mono-crystalline
OCC copper); and (b) multi-strand cables; both of which lead to current
jumping from one crystal/conductor to the next through suggested copper
oxide rectification at adjoining surfaces.
If this is so I would expect "bad" cables to measurably generate
intermodulation products. A bit of research on Google, however, draws a
blank. Are there any references?
None that I have been able to find so far. The above claim is one I've seen
a number of times in adverts, articles, and cable-maker websites. Yet - as
with some other 'technical' claims - when I question the makers I don't
seem to get reliable references or plausible physics.
If someone knows of some good references to measurements of the above
(alleged) effect I'd be interested to know. Ditto for various other claims
cable makers assert.
Slainte,
