New Omega E Mat from Perfect Path Technologies

Many of you own or have read of the highly-regarded PPT Omega E Mat, one of Tim Mrock’s revolutionary signal-enhancing accessories. Just prior to his untimely passing, Tim had finished developing a new generation of his Omega mat, soon to be available. Krissy Mrock has asked a few of us to introduce this new mat, here given the working title of The Double Omega.

In distinguishing the Double Omega, we know the original Omega, herein called the single, as a 7.5” by 10”, rather heavy and somewhat pliable mat, a bit more than 1/8” thick and with a vinyl-like feel. One face is glossy white, displaying the PPT logo and Omega name, while the other is black, smooth and magnetized. Sandwiched between these faces is the active material that causes components to reject the EMI that saturates everything in our surroundings. The Double Omega is much the same, with one important difference: the magnetized face has the finely-textured feel of around, say, 220-grit sandpaper. This texture, it is presumed, comprises yet a second active layer of EMI rejection. Presumed—because working details of the Double Omega are not well understood—better yet to know how to apply it.

With the understanding that the single Omega E mats generate field effects from both faces, mats have typically been placed under and over components and vertically over circuit breakers. How you apply the Double Omega will depend on best use and experimentation. In my case, I have removed two single mats, lying side-by-side, from the top of my large Wadia CDP and have replaced those with two Double Omegas. The Wadia is a one-box player that contains a pre-amp, so I wanted that second, strong field effect exerting downward as well as upward. I also have several singles placed underneath, just as before. Going straight to amps, this player is my only source, so I want it fully protected from EMI. Your priorities will differ.

As of this writing, I am only thirty-hours in on placing these Double Omegas, and I can already tell you they are powerful in their prevention of EMI within my digital source. Yet another veil has been lifted—all instruments and voices are even more sorted out in the aural space with new information heard within that space. There is much more decay heard against a new silence behind and between the musicians. I am already so pleased and excited about what the Double Omega E mats are doing. As Krissy told me, Tim was really stoked to have these new mats available. Rather than wait for the the fourteen-day window of improvement, I want to get this intro out so others can relay their experiences sooner.

Due to house repairs and installation of bass traps etc. I have only recently introduced E Mats and TC into my system. Some Application of TC was done about 3 months ago and the Mats about 3 weeks ago.

The stuff certainly, beyond any doubt, makes a significant difference in my system. And not for the good!

What it does is render it over the top bright and harsh. Unlistenable to the point where my wife screws up her face while I dive for the volume control.

I have changed out interconnects and tried a permutation of different power cables and swapped between silver and copper wiring on the linestage inputs but with the sound overpoweringly bright, non of this made any difference.

In case you're wondering about my kit, I'm able to clearly hear the sound change when altering the position of a stock fuse.

I have tried bypassing my linestage 'The Truth' and going direct into a Wadia15  This DAC is normaly in no way bright, but the system becomes a screaming, screeching monster with the 9 mats I have.

The system is slowly returning to its previous state after 3 days of mat removal. These things are decidedly powerful.

I was not sure where to post this problem I have.

They were all the original mats. Also, to be clear, I removed the linestage from the path and took the analogue-out from the DAC directly to the power amp.

I hope somebody can shed some light on this as all I am left with is the empty feeling of wasting a large sum of money.

@geoffkait: Yes I have made changes by shufflling cables around but that was done to try and smooth out the sound. I soon realised that no cable swapping could sort out the problem. The bass traps and other room treatments were in place before the problem raised its ugly head. I have never found bass traps to harm the sound, to the contrary the results have always been greatly beneficial and sometimes astonishing. Measurements show a much improved response and my ears agree. The measurements also show that I need more.

@jafreeman: I appreciate the sympathy. I too have not come across a negative comment and the effusive praise heaped upon these products is what convinced me to buy them, expecting wondrous things to happen.

The above comment shows in a negative light, the posters who relentlessly insist on the placebo or expectation bias effect. Those guilty of this mysterious tactic might try and explain this effect considering the money I have spent and the fact that my wife and I were both really looking forward to and expecting the rewards, the deeper immersion into and the simple pleasure of music, over and above what the acoustic treatments brought.

@oregonpapa: I have no magnets anywhere and agree that something definitely is not right.

@Ipretiring: I intend to experiment with these mats but will certainly contact you should I decide to sell. They are sitting in a disgraced heap at the moment being eyed by my wife to use as non-returning boomerangs. I am interested in your findings on The Truth either on this thread or by PM if more appropriate. I took a chance buying unheard, when I realised that my DIY valve linestage had developed humm and required rebuilding.

@grannyring: I am using as speaker cables and power cables Duelund cotton covered wire which I think you have a lot of experience with. I found an Oyaide PC better suited, in my system, on my DAC but liked the Duelund on an Oppo and linestage. Speaking of which, I am very interested in the mods to your unit and in which way it was improved. I ordered mine from Ed with upgraded OCC solid core wire on inputs and outputs. I was intending to replace the supplied standard RCA sockets with quality low-mass ones. If you could PM me with details of your mods I would be most grateful but will understand if you don't.

Hey Tom, very interesting and I will certainly do that. It is something I was not aware of.  Many thanks.  Music is now sounding a little more relaxed, not so over-hyped and almost listenable again.  My wife and I  decided to watch a movie for a change and have just finished watching Late Quartet. Superb acting and great music.  4 ****
