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.

Synergistic Research High-Frequency Transducers (HFTs) were really substantial in getting my room calmed down. This in spite of many other room treatments already aboard. 

I would proceed like this:

1.  A ten-pack of SR HFTs placed around the room as directed.
2.  A tube of Total Contact. Paste all connections as directed in the TC thread.
3.  Omega E Mats ... as many as you can afford.
4.  SR ECTs.
5.  PHTs.
6.  Save up money for the upcoming Perfect Path Technology "Gate." From what I understand, it will be a real game changer.

All of the above assumes that by now you've experimented with proper speaker placement, have selected good sounding wire and have good electronics.

Sounds like I need to get the HFTs. Five of the original and five of the warmer 2.0 I think?
millercarbon:

I have treated two different shaped rooms with the HFT family of transducers. I think you will have very good results with 10 HFT's (two boxes) and then one box of the warmer HFT-2.0.

This combination should give you a very nice sounding room and also give you a good idea of  how these products work.

My room is approximately 17x24 with a 9 ft ceiling, wall to wall carpeting, fabric over the lower 3 ft all the way around, 14" triangle tunes in the 4 ceiling corners where walls meet ceiling, with similar panels of Owens Corning fiberglass panels running most of the length of where the walls meet each other as well as running around where the ceiling meets the walls. The best way I know to tame reflections the most with the least material and the most effective treatment I knew of until now, but it gives you some idea where I'm starting.

The biggest thing I wonder about is while this room is two channel listening driven it also is my home theater with a nearly 9 ft wide projection screen on the back wall some 6 feet behind the speakers and extending down to 32" above the floor. It seems that gives me only a small vertical area to experiment with one or 2 HFT, all just below ear level from my sweet spot. But maybe that will turn out to be not all that much of a restriction anyway?
As it stands i am quite happy with the way my music sounds,
espiecally at night , but the tweaking bug itches ever so often .
I live in Germany and buying from the USA involes  duty and 
sometimes having to drive out near to the air port to collect  stuff ,
even if it's posted with UPS.
I will order from England.
