I am not upset but you have no idea how much a cable can contribute to the sound of a system. Switching to Synergistic Research Tesla cables was easily the single biggest and most clearly audible improvement I have ever made to a system.
LM and Redwood,
I believe LM might be using "Active Cables". The speaker cables need to be plugged into the wall and the shield is activated with a DC current with return on a separate ground wire. A buffer circuit is added between the Shield and ground wire. About 30 Volts DC is applied. Details are, of course, proprietary, although anyone with $3000 or so to burn could cut them open and check the circuits.
Speaker cables with active power and buffer circuitry will without doubt have the potential for much greater impact to the sound than ordinary wire. No wonder it made such a big difference to LM! Far from having an ordinary brown dog or black dog, you could say LM has a white unicorn - you know something entirely different and quite rare...not even the same species as what ordinary folks would consider a dog.
