Galen Gareis presented the following talk at the Masterclass Sessions at the AXPONA show, titled "The Uncommonly Understood Nature of Common Cable Characteristics."
Technical Papers: Iconoclast Cable
Video posted on this page.
As an engineer for 4+ decades, I found this fascinating. Especially since most of my EE peers did not have the knowledge of cable design. This should be a must see in entirety for all the cable naysayers.
Anyways, he does make a few comments toward the end about why E-stats can run better with a different cable than most box speakers being fed by standard amplifier.
Hope this helps.
