Less-Loss anyone?

Has anyone heard of Less-Loss cables, my friend claims his new power cable is the most dramatic improvement to the music he has ever heard.

@mdrone - The Firewall for Speakers has two distinct ends one with terminal connections for the speaker cables , the other end has built in cables that are connected to the speaker terminals

I have not tried the Firewall for Speakers on my newish Fidelium speaker cables. The thought of wrestling with my cables behind speakers, etc. is always agonizing and causes procrastination. Any thoughts with using the Firewall for Speakers on the Fideliums? Jeff of Silversmith was skeptical but did not dissuade.  Neal

@nglazer I can't specifically answer your question as I have no experience with the Fidelium cables

Always a fan of LessLoss. Have to say full loom from Mad Scientist Audio is far more musical for less cost. Still use AC and speaker FireWalls.
