Math + Logic + Science = something completely mad...

So, I've done a metric fuckton of research, notwithstanding the clear bias the man who designed and built my Belles has against esoteric cabling.  And here's the conclusion to which I arrived. 

My monoblocks are sitting on top of the speakers.  The distance from the amp to the speaker is barely a foot, which is exactly how long a run of wire I intend to use.  Goal is to minimize the effect the wire has on the sound.  

According to the calculations I've seen and done, the skin effect depth on copper wire at 20Khz is 461 micrometers.  Meaning a 19-gauge copper wire (911 mics diameter) would reduce skin effect to zero.  As in no impact whatsoever on the signal. 
 
Of course, it's actually very difficult to find 19-gauge wire.  18-gauge (1024 mics) is much easier, and the skin effect is near zero, but not quite zero.  Seems to be an acceptable compromise. Could go down to 20-gauge and eliminate skin effect entirely.  If I could find insulated aluminum wire, 18-gauge would eliminate skin effect entirely, because skin effect depth on aluminum at 20khz is 580 mics.  

12 inches of 18-gauge wire produces 0.006 ohms of additional resistance.  20-gauge = 0.01 ohms.  

Frankly, I don't see the value in spending big bucks on esoteric, heavy-gauge wire for this application.  I'd rather make the bigger investment in the 2m runs from the preamp to the blocks, because that's where the wire's going to have a hell of a lot more of an effect on the sound.  

Stepping back to allow you all the opportunity to punch holes in my thought process here.

We end up where we started R, L, C.
And now comes the money question.

Presuming that I shelve the amps a few inches above the speakers (already bought shelf kits to do this), now I still have my 12-inch speaker cable run, BUT, I still have 2.5 meters between the amps and the pre.

So now I have a milliwatt signal being broadcast on a longer run than the high-watt signal between the amp and the speaker.

It seems to me that C should be my biggest concern when I contemplate my interconnect choices due to the longer run, though RCA cables tend to be far less transparent regarding their specs than basic speaker cable.

Your advice would be useful here.

Use mogami balanced.

dletch2, I'm trying to describe what I hear, while you're saying I have to be mistaken because something like that does not exist.  That is my whole point - you're starting from the wrong side, trying to disprove what can easily be heard.  You also imply, that I wouldn't be able to tell the difference in blind test.  Are you a cable naysayer who tries to fortify it with measurements?  Let me suggest, that placebo effect exist both ways - if you strongly believe that you cannot hear the difference you won't.  Also, there are people with less then perfect hearing apparatus (I'm not suggesting it applies to you) who get very defensive about it making crusade against cables on cable forum.   I'm sure my hearing, even at my younger age, wasn't as good as hearing of many other people and I would never dare to tell them what they can or cannot hear.

Use mogami balanced.

While I'd love to go XLR for that application, it's simply not an option, because the pre only has unbalanced out, and the amp only has unbalanced in.  So it is what it is.  Unless Mogami has some fancy way to get the cancellation out of the XLR and still convert to RCA on both sides, then we gotta find a different solution.
