Perfect Path Technologies: Omega E mat
I’m curious about this product from Perfect Path Technologies and would like to hear from those that have experience with it. I’ve bought and used the Total Contact enhancer and like what it does for my system so I’m interested in hearing how this Omega E mat performs.

I know for a fact that Hallographs are not cheap to manufacture. The wood costs about $175 to $200, as stated nice pieces of ebony aren’t cheap. They are not made in huge quantities so machining them costs another few $100s. Probably a 3X to 4X mark up. Compare that to Synergistic Research tweaks-there’s a big markup. Also many of their products are worth the money in sound enhancement value. The Hallographs are the most important acoustic tweak I have, more than the SR HFTs and the PPT E-Mats. Without Hallographs, I would need better speakers (better imaging ones). |
I’ve been messing around with magnets in my system for the last six months or so which you can read about on my system page. I’ve now added Tim’s products as well. Tim indicates they have nothing to do with magnetism but they certainly work as advertised and compliment what I’ve heard by adding magnets. Just thought I'd share some interesting reading: Spintronics A conventional digital electronic system conveys a binary signal (think 1s and 0s) through pulses of electrons carried through a conductive wire. Spintronics can convey additional information via another characteristic of electrons, their spin direction (think up or down). Spin is related to magnetism. So spintronics uses magnetism to align electrons of a certain spin, or "inject" spin into a system. If you've ever done the old science experiment of turning a nail into a magnet by repeatedly dragging a magnet along its length, then you've already dabbled in spintronics. The magnet transfers information to the nail. The trick is then transporting and manipulating that information, which requires devices and materials with finely tuned properties. Researchers are working toward the milestone of a spin transistor, a spintronics version of the electronic components found in practically all modern electronics. Such a device requires a semiconductor material in which a magnetic field can easily manipulate the direction of electrons' spin -- a property called spin-orbit coupling. https://www.sciencedaily.com/releases/2019/01/190110160941.htm https://en.wikipedia.org/wiki/Spintronics https://www.sciencedaily.com/releases/2015/05/150505082944.htm https://phys.org/news/2018-05-graphene-layered-magnetic-materials-ultrathin.html

Well, if you want to get into it, I strongly suggest you read all about magnets and colors and sound in the link at the bottom of this post. In my humble opinion bringing atomic physics or spintronics into the discussion can serve no porpoise. 🐬 I’m probably the only one on this thread schooled in atomic physics. As a point of reference I’ve been using magnets in audio systems - as well as some of my products - for more than twenty years. Magnets 🧲 are tricky, though. Magnetic things are generally not (rpt not) good for the sound. Which is why you don’t see too many steel chassis anymore. Or magnetic screws or connectors, for that matter. And why treating the circuit breaker box panel is important. Magnetic fields are usually things to be scrupulously avoided. Magnets are like pills, some make you tall, some make you small, the ones that Mommy gives you don’t do anything at all. As for colors, they’re electromagnetic, no? So colors 🌹 and magnets 🧲 kind of go hand in hand. 🤚 Your friend and humble scribe, geoff kait machina dynamica advanced audio conceits http://www.pwbelectronics.co.uk/wp-content/uploads/2015/05/MagnaBlocks.pdf |
sbayne “There’s a lot we don’t know, especially at the quantum level.” Who said anything about the quantum level? Are you keeping some secret quantum information from the group? 🤫 You don’t know what you don’t know. It’s getting to be so there’s no demarcation line between classical physics and quantum physics. There is a difference between quantum mechanics and nanotechnology. The CD laser is quantum mechanics. The CD itself is nanotechnology. Einstein never got on board the quantum mechanics train 🚂 so no harm in either rejecting it. I’m not sure what the right thread would be for a discussion of spintronics. “If I could explain it to the average Joe they wouldn’t have given me the Nobel prize.” |
stevecham - I’m pretty sure you’ll find the following paragraph of interest. Yes, PWB in Leeds is of some concern. 😛 “While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer ("light-mill"), a device invented in 1873 in which a rotor (having vanes which are dark on one side, and light on the other) in a partial vacuum spins when exposed to light. A common belief (one originally held even by Crookes) is that the momentum of the absorbed light on the black faces makes the radiometer operate. If this were true however, the radiometer would spin away from the non-black faces, since the photons bouncing off those faces impart more momentum than the photons absorbed on the black faces. Photons do exert radiation pressure on the faces, but those forces are dwarfed by other effects. The currently accepted explanation depends on having just the right degree of vacuum, and relates to the transfer of heat rather than the direct effect of photons. [2][3]” Also, If photons had mass they couldn’t travel at the speed of light. |
The Big Bang “expansion”, when things are undefined, lasted about 10 to the minus 30 seconds. The entire Big Bang took about a billionth of a second. If photons had mass don’t you think the military would have photon weapons that operate by mass at light Speed? They do have laser weapons but those operate via high heat not mass. Hel-loo! Big Bang timeline Inflation and baryogenesis The earliest phases of the Big Bang are subject to much speculation. In the most common models the universe was filled homogeneously and isotropically with a very high energy density and huge temperatures and pressures and was very rapidly expanding and cooling. Approximately 10−37 seconds into the expansion, a phase transition caused a cosmic inflation, during which the universe grew exponentially during which time density fluctuationsthat occurred because of the uncertainty principle were amplified into the seeds that would later form the large-scale structure of the universe.[25] After inflation stopped, reheating occurred until the universe obtained the temperatures required for the production of a quark–gluon plasma as well as all other elementary particles.[26] Temperatures were so high that the random motions of particles were at relativistic speeds, and particle–antiparticle pairs of all kinds were being continuously created and destroyed in collisions.[7] At some point, an unknown reaction called baryogenesis violated the conservation of baryon number, leading to a very small excess of quarks and leptons over antiquarks and antileptons—of the order of one part in 30 million. This resulted in the predominance of matter over antimatter in the present universe.[27] CoolingPanoramic view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. Galaxies are color-coded by redshift.The universe continued to decrease in density and fall in temperature, hence the typical energy of each particle was decreasing. Symmetry breaking phase transitions put the fundamental forces of physics and the parameters of elementary particles into their present form.[28] After about 10−11 seconds, the picture becomes less speculative, since particle energies drop to values that can be attained in particle accelerators. At about 10−6 seconds, quarks and gluons combined to form baryons such as protons and neutrons. The small excess of quarks over antiquarks led to a small excess of baryons over antibaryons. The temperature was now no longer high enough to create new proton–antiproton pairs (similarly for neutrons–antineutrons), so a mass annihilation immediately followed, leaving just one in 1010 of the original protons and neutrons, and none of their antiparticles. A similar process happened at about 1 second for electrons and positrons. After these annihilations, the remaining protons, neutrons and electrons were no longer moving relativistically and the energy density of the universe was dominated by photons (with a minor contribution from neutrinos). |
uberwaltz ... I don't have a streamer, strictly CD's and vinyl here. BUT I am using E Cards on my TV's satellite box and recorder to great benefit. Similar improvements from the two E Mats in the circuit breaker box. Better sound, better color saturation, and a clearer picture. Works really well on my 73" Mitsubishi rear projection TV. Maybe others can chime in on music servers. Frank |
tlong1958"I don’t see why they deleted the post that mentioned my sphincter" I don't think readers here are very interested in your sphincter, your anus, or the lube you use regularly to insure that they are always slippery and ready for the "fun and action" you enjoy. |

All the more to put in your mouth i guess? 😁😁 No, more like another foot to kick your lame rear end with. 😬 One assumes, judging from your repeated dull reactions, they don’t teach humor in UK. Or much of anything else, for that matter. 😃 |

<3 Yes. It's a Facebook thing. <3 It turns them into actual floating hearts. Everything is said with love. <3 Indeed. <3 Mémère used to say, "In a world where you can be anything....be kind." <3 Streaming? I have a few Alpha Cards under my ROKU player. <3 I <3 LOVE IT. <3 Less....nix that.....ZERO buffering. It's a pretty big deal for us.... being we live in the sticks. <3 lol They also work well on the modem. <3 A noticeable difference. <3 I lined up 6 Ecards under my Mac Book Air. <3 It seems to run cooler and charge faster. <3 OH. And the fan doesn't kick on so often when I play Candy Crush. LOL. <3 Small but powerful. <3 <3 An entertaining and highly intellectual group of fellas. <3 We love to read this thread. <3 Thanks so much! <3 Krissy |
uberwaltz... I have a bedroom system that consists of my computer (PC), and a pair of Audioengine A2+ powered speakers. Just using the stock speaker cables that came with the speakers. I put E-Cards on top of the speakers, and on top of the PC. The results are very satisfying. 1. The computer screen has a much better picture. Great for cruising YouTube videos. 2. The music from my Spotify account is much better. The speakers completely disappear. The music has a lot more body. Better 3-D imaging. Lots of depth. The real payoff is how relaxed the music has become and how visceral human voice is. Love those sultry female ballads! :-) Listening to a live recording of Mel Torme at the moment. Delightful! I'll leave everything in place overnight and report back in the morning. Frank |
