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.

Here’s Tim’s main system ...

Speakers - Newform Research 645’s.

Sub Woofers - Gallo.

CD Player - Consonance - with the stand.

Amps - Unico DM Italian amps.

No pre-amp.

Power supply - Huge unit made in the 1950s that Tim modified.

Cables - All custom built by Tim using the same technology that is in The Gate.

All electronics and the complete interior of the speakers, including crossovers and driver baskets, are completely treated with Total Contact ... plus a Gate in the circuit breaker box and mats galore everywhere. I think Krissy told me that Tim had eighty (80) mats throughout the system.

I can attest to the quality of Tim’s cables. He sent me two power cords that he had built for the show to try out. I had them for three weeks. They were fantastic and much like adding another Gate to the system. I went through a total withdrawal when I returned them. I can only imagine what an entire loop would sound like.

Then there was the second system that he built for the show. For the life of me, I cannot remember the brand of the speakers, but they can be bought at Best Buy for $1000. Tim bought his used at an auction for $165 for the pair. The amp was the new Mac integrated, New Mac CD player and that power supply that Tim had built for the main system. Then with all of the above wires, and the speakers totally tricked out like above too. The idea was to get really great sound from those speakers that almost anyone can afford, and have the system blow everyone’s mind. He even made special room treatments that he told me were absolutely fantastic.

The guy was a genius.

Very interesting post Oregonpapa...

It is my experience, without the genius of this guy for sure, that almost all people already own more than correct gear for an audiophile experience of the first order, modulo room treatment, vibration-resonance controls, electro-magnetic grid of the room and the house treatment and some other supplementary tweaks... Interesting thread.. 

All my sympathies goes to his friends and family .My best to all...

Tim and I talked about simple things that can make for a nice improvement. One was my mention of replacing all the steel fasteners holding down his speakers, diaphrams, and crossover components. Brass is nonferrous, and has low or no inductance. He was blown away with the improvement even on the ribbon drivers..that supprised him the most.


We both painted the baskets of the drivers and for myself I painted the bezel around the tweeter. Tim treated his entire speaker in segments and then when he knew how great the improvement was he painted the whole darn thing. When one was complete it just disappeared and he had to jump right over and treat its mate..For me once the paint cured there was a nice improvement. But I didnt have  buckets of paint so I was more selective in my treatments such as the brass screws. Nice even more.

He told me his speakers for the show were a fairly recent but discontinued Klipsch RP series 2 way. Dual 8 model with horn tweeter.
He told me he wanted it to remain stock for the show...adding only his magic treatments to all the stock components. I think he treated the inside of the cabinet and told me he built his own wiring harness and treated that as well. When he told me about this speaker pair he modded and how it sounded he was as giddy as an 9 year old at Christmas..He built it as a showcase for his products and their application. He didnt change the crossover components or values..no brass fasteners no new isolators or couplers..all stock. The newer Klipsch series speakers are quite good. I know I have sold them in the very recent past. At no time were the speaker drivers treated..only the stationary parts.

Tim was a great guy.. smart man and he was a great listener and always had an idea on fire.  Will miss you Tim ...So says Tom.

Nice post.

I had second thoughts on posting Tim’s suggestions to improve my speakers, but now that you’ve brought it up, here it is:

Tim called and asked me if I had a felt-like material around the outside of the drivers on my speakers. I said that I did. Tim suggested that I paste the felt material with Total Contact. I thought ... riiiight. Well, I did and the improvement was immediate.

Then he called back and said that he had done some research on my speakers and suggested that I VERY carefully apply a thin coat of Total Contact to the screens covering the Dual Air Motion Tweeters. I did, then sat back and was shocked at how much better the highs became.

After that, I took the access cover off of the crossovers and pasted everything I found there. Zowie, another improvement.

There’s a lot more to Total Contact than just coating the ends of a cable loop.

Tim's main system is indeed impressive. I have had the pleasure of hearing (and seeing) it, too briefly, when I visited him. I wish that I could spend more time listening and really getting to know what it's capable of. It is clearly a labor of love by a true audio and music enthusiast. Tim had no fear of trying new things, and that is a big part of how he came to develop these groundbreaking products.
