What reasoning?

Absolutely.

This is a genuine question even though it may be taken otherwise: is
audible frequency response deviation from flat either an acceptable or
a desireable factor in a cable?

I'd say not. If you need to make small changes to the EQ a hardwired cable
seems pretty crude, especially given the lack of information on the curve
they provide. Using the tone controls or getting a dedicated EQ would be a
beter choice.

Well there is an ulterior motive to my question which is to get some
clear idea of what known effects can be eliminated as the cause of any
cable sound differences.

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,

Jim
