Perfect Path Technologies: Omega E mat

One reason it’s not really fair to discuss High Fidelity Cables in the context of magnetic fields and using magnets or demagnetizers in audio systems is because High Fidelity Cables use magnets for the actual conduction of the signal (I.e., magnetic conduction, his term) as opposed to trying to “manipulate the signal.”

Also it should be pointed out that the conductive element in HFC is not copper or silver but a high permeability alloy, you know, for absorbing/shielding magnetic fields. I suspect a pretty good cable or power cord could be made using that same high perm alloy in lieu of copper or silver and just skip the magnets. You know, since the current flowing through the conductor produces a magnetic field, one that is most likely not too good for the sound. Yes, I know what you’re thinking, well, what about all the other wire and cabling in the system, including the internal speaker wire and transformers? Bingo! 😛

From the GroverHuffman.com site: . "All cables incorporate my painstakingly designed state of the art carbon, tungsten, nickel shield that neutralizes Electro-magnetic influences on the signal both from within and without."   He binds the powdered carbon, tungsten and nickel with a glue than hardens on the mesh copper shielding.  The ribbon conductors are air core insulated within a teflon tube, whereby both tubes are shielded by the RF/EMI/magnetic mesh copper shield (and also results in very low capacitance).  This is an alternate way that cabling can eliminate magnetism effects (and painstakingly time consuming production method).  

I would not advise using E-Mats placed on cabling based on it's partially magnetic design.

This doesn't make one right or wrong. Having gone to many audio shows over the years, I've heard speakers that others have loved, but didn't do anything for me at all. It's all subjective.

>>>>See, I have a somewhat different experience, also having been to many shows and having been part of many high end systems at shows. I rarely hear anything that sounds really good and much that sounds really bad.

“Painstakingly designed.” Ah, a true artist, willing to suffer for his art. 😩 

I'm mostly in agreement with you Geoff.  The last show with about 100 exhibitors had four really excellent audio systems.   Two were laughably bad (a glass enclosed speaker with a Kronos analog front end that was thin and bright and a wood cone two way speaker sounded hollow and dead).  Wouldn't you know it, some critics wrote how they enjoyed the worst sound at the show. 

Most rooms were okay but with sonic problems, some attributable to the room acoustics, some due to setup and some due to equipment (resulting in bright upper mid Focals, dark and funny sounding Magicos, etc.).   

But, everyone (including 7 or 8 critics who wrote about it) who has heard the Von Schweikert Ultra 11/VAC/Kronos room at about half a dozen shows were transfixed by the musicality of the reproduced music.  Funny, I didn't see any SR tweaks or E-Mats or other tweaks in the room-some ultimate systems just sound fabulous without them.  On the other end of the cost spectrum, a $7500 Volti horn speaker with a $9000 La Perla Audio integrated amp, $2500 analog w/a Dynavector 20x2 had people (like my wife and I) enjoying all types of music (jazz, orchestral, rock) for half an hour at a time.   That's a system I would try tweaks on like TC and E-Mats to bring more air and wider soundstage to it.
