Synergistic Research ECT


Many years ago, I'm going to say about 20, a fellow named Michael Greene came out with a rack that purported to improve performance by clamping components between the shelves. Preposterous, I thought, and wrote a letter to the editor telling him so and asking to please not waste my valuable time with such nonsense. A letter I soon came to deeply regret. Because within a year I had heard for myself what vibration control can do. Today the value of vibration control is (or should be) clear to all audiophiles.

So that's Preface Part One: Don't knock it if you haven't tried it.

Preface Part Two: Don't be so sure its not there just because you can't hear it. Learning to recognize and describe what you are hearing ain't necessarily easy. I used to drag my wife along to audition CD players, because I wasn't entirely sure myself if what I was hearing was there or in my head. When time after time she said, "yeah it sounds better, I can't say how or why but this one definitely sounds better" I knew it was for real. Now I'm able to hear in a flash what I used to agonize interminably over. But it did take time. And effort.

And so with that out of the way and everyone understanding this review is for those who either have the listening skills or at least would like to develop them, my recent experience with the Synergistic Research ECT.

Now according to Synergistic, and a ton of reviews, these things work pretty much everywhere. Well, to a guy like me, them's fightin' words! Nobody ever said anything about using them on a turntable motor. So that's right where the first one went. Right onto the top of my Teres Audio rim drive Verus motor. Just stuck the thing on there. Its not gonna work. No way it can work. On a motor? No way. Waste of time. Sat back down and... what the.... dang... seriously? Its on the bleedin' motor! How's that work?? BS! Witchcraft! Got up and removed it. Uh, no, bad idea. Put it back. Ahh. Much better.

With the ECT stuck on the motor everything in the soundstage took on a more palpable reality. There was a greater sense of depth, and air or space around each source. Not wider or higher, nothing moved around from where it had been. When I say greater depth, its not like anything moved closer or further away. The feeling of depth is hard to describe. A lot of it comes from a greater sense of being more immersed in the recording space. Bigger recording space, bigger room, greater depth. Something like that. Removed, the presentation went flat and grainy. Funny, never seemed there was any grain or etch before. One New York minute with ECT and remove them though, yeah, there's grain. Stick that thing back on there. Inner detail. Sense of ease. All better now.

That's just one. On the one place nobody said they would work. What about where they ARE supposed to work? I stuck one close to the base in front of the D101 power supply tube on my Melody Integrated. OMG, here we go again! Same thing. Here I also noticed improved dynamics and a lower noise floor. Heard this with the one on the motor too, and its hard to say which location had the greatest effect on which. I guess, to be really systematic about it, you could move one around trying a dozen different spots, looking for the biggest effect. Actually did that a long time ago with a Shakti Stone. Overpriced waste of money, that. Not so these. When something works this good, you just want more.

But first, I did of course try removing it. Just to be sure. Still hard to believe. Putting it back, this time I placed it behind the tube. Same result. What about transformers? The power transformer on the Melody is big and heavy, and encased in some sort of shiny black stuff, plastic or whatever I don't know. For sure there is no way a tiny little dot of aluminum (for the record, I have no clue what its made of) gonna have any effect on something that big and massive. Only, it did. Same. Exact. Results.

Crazy.

For those keeping score at home that's 3 ECT's deployed. They come 5 to a box. Only used about half, already happy. Which gets us to, what's it worth? My longstanding Gold Standard for tweaks is Black Diamond Racing Cones. At $20 each and needing 3 per component they coincidentally come in at the same $60 per ECT. Comparing apples to oranges I would say one ECT comes very close to three Cones. Not quite there. But close. Considering nothing I've ever heard comes close to BDR for the money that's pretty high praise indeed.

If I were to buy some of SR’s passive tweaks, which would it be first? The HFTs?

I have none

I do have acoustic panels from another brand for first Reflection points on side walls, and behind speakers (back wall is too far, over 12’ Away). Can these be put on top of acoustic panels?
thyname- Good questions. I have tried ECT, PHT, HFT and Blue Quantum Fuses. They are all amazing in terms of what they do for what they cost. Maybe the biggest bang for the buck to me seemed to be the Blue Quantum Fuse. After I heard what one did for my amp I put them in everything.

After that its hard to say. In my case I did PHT then ECT then HFT. By the time I did the HFTs it seemed like they maybe made more improvement than the ECTs. But on the other hand the HFTs work by introducing dither to smooth out room resonances in much the same way noise is added to a video signal to remove color banding. So it may be that part of the reason they worked so well was the signal had already been improved by the ECTs. In any case they all work so well its hard to see you stopping with just one or the other. 

A more practical consideration might be how easily you're able to use them in your room. With ECTs its easy, they work really consistently well everywhere I have tried them. I even opened up my amp thinking they should work better placed directly on the parts inside than on the case outside, but that turned out not to be the case. Too close to call. ECTs even work on my turntable motor, and arm mount. 

PHT work great right on the cartridge, but also just about as good when placed on the arm. I tried various locations. Also they are additive, and don't seem to conflict at all with each other nor with ECTs. I have both a PHT Black Widow and Green Dream on my cartridge, and another Green Dream on the arm, and one ECT on the arm base and another ECT on the motor. 

HFTs on the other hand are sensitive to placement. Please note I said sensitive not finicky. Stick them virtually anywhere in the general vicinity of their recommendations and you will be amazed. Then play around and you will find you are able to fine tune things to an impressive degree just by shifting their position an inch or two.

You can try them stuck directly on a panel but they seem to work better when firmly mounted to something solid. Also their placement recommendations are quite a bit different than what you would use for old-school acoustic panels.

They all come with a 30 day no-questions money back guarantee. The only ones I ever sent back were the Purple Haze and Blue Velvet PHT, and that is because those come in different, uh, flavors. Unlike HFT and ECT which seem to my ears to be very neutral and just make everything across-the-board better.
PS- scope around for posts by pritchard, sgordon and oregonpapa, plenty of good experience and info from them too.
Thanks @millercarbon! I am more confused now than before 😂😉  I know, not your fault
