Welcome
And to your question. yes and no.
"Everything in Audio Seems to Make a Difference" sometimes good and sometimes bad, and the only thing that matters in audio is "What you Personally Hear and How You Like It".

Welcome!
I agree with Jock...the variations on this huge theme of what sounds good,what affects sound and what you change in a system all have a significant impact on how it sounds to you.
While I have read that "skin effect" has an effect, I simply do not have the ability or tools to meaure or quantify such esoteric meanderings into this hobby/passion/obsession of ours.
Suffice to say, if it sounds good to me, I go with it.

Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor. The electric current flows mainly at the "skin" of the conductor, between the outer surface and a level called the skin depth. The skin effect causes the effective resistance of the conductor to increase at higher frequencies where the skin depth is smaller, thus reducing the effective cross-section of the conductor. The skin effect is due to opposing eddy currents induced by the changing magnetic field resulting from the alternating current. At 60 Hz in copper, the skin depth is about 8.5 mm. At high frequencies the skin depth becomes much smaller. Increased AC resistance due to the skin effect can be mitigated by using specially woven litz wire. Because the interior of a large conductor carries so little of the current, tubular conductors such as pipe can be used to save weight and cost.
Hi Devis,
I don't want to sound petty (
) and perhaps it was just an oversight on your part but especially with technical topics such as these, please credit your information sources if you are posting words / comments other than your own: Skin effect - Wikipedia, the free encyclopedia

To technical for me.
But thanks to both for explaining.
