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.

I use the Synergistic Research ECT’s in my components and am very impressed with the sonic improvements they create. It is an easy experiment to do as there is no break in time after installation. 

Both front end equipment and amplifiers ( Tube and solid state) respond. It is a bit of try a location and listen. If better leave one there and try another location. If no change or worse remove.

Most pieces of equipment will benefit from 3 to 7 ECT’s being installed.

With the December sale of a free Blue fuse with a Box (5) ECT’s I think this is a very good deal.

David Pritchard
The Synergistic Research family of transducers -HFT's, ECT's, and PHT's are amazingly effective and easy to use. The HFT's now come in five different types and are now the cornerstone for acoustically treating my listening room. Each piece of equipment also has at least one ECT on it, and most have several.

And it is nice that if you sell that piece of equipment or change the listening room you can keep these devices for the next application.

I have not  personally tried the PHT's as I do not have a turntable. But I have tried a HFT original model and then an ECT at the same location on an amplifier. Two different flavors of sound. Fascinating to me that there is such a significant change in sound.

I do hope you will trial the different PHT's in your system. SR is very good about their 30 day return policy. I have also found their written descriptions of their products to be accurate.

Glad you finally got a day off work!

I agree the Synergistic Research ECT's are amazing. I find their placement to work well on both audio and video systems. One of the good things about them is the effect is immediate. Try a spot and watch or listen. If improved leave it, If worse or no change remove it.

You can put too many in a component and get a sound that becomes lean. But they are easy to put in and out and so a bit of experimentation is in order. They do come with some suggested sites to try.

When placing them for a temporary listen, I do like to use a dab of DAP brand sticky putty called Blue Stick (bought at Home Depot). Once I have finalized placement, I prefer to more permanently attach them with a High-Temperature glue gun. This adhesive does not melt or run even in a high-temperature environment such as my Pass Lab amplifiers. It just takes one Small drop of glue to affix the ECT. They still can be removed at a later date if necessary.


The ECT is effective, easy to use, and if you do not like them you can send them back.

David Pritchard 
Yes. There is a marked reduction in grain and glare that allows the music to sound better and video to look better.

The sonic benefits of Total Contact and the SR ECT’s work hand in hand.

Tawa:
The good news is all of the mentioned Synergistic Research products work , and also please do not forget their wall outlets and fuses also make a significant difference.
Perfect Tecnologies Total Contact and their Omega E-Mat also have a beneficial effect.

The big question is where to start. If your budget is $300.00, I would get a tube of Total Contact and treat the circuit breaker box wires. In my box that was about 80 contacts. This will decrease noise in all electrical circuits in the house or apartment. This can be thought of as establishing a good foundation to better sound.

If my budget is 1500.00 I would get the Synergistic Research HFT’s and treat the acoustics of the listening room (even if the room has been acoustically treated with other products).

Then I would use Ect’s, outlets, and fuses.

I use all of these products myself.

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. 

David Pritchard
Tawa:
I have only once had the customs hassle but it was a major inconvenience. That sounds like a good plan buying thru England.

Total Contact is only available thru Perfect Path Technologies located in the USA.

David Pritchard
Millercarbon:

I think you will enjoy experimenting with the HFT’s as they are so easy to attach and remove. I especially do like using the DAP brand Blue Tack (I buy mine at HomeDepot). Easier to remove the adhesive that what comes with the HFT’s.
You should be able to trial the HFT’s on your acoustic panels and even consider the outer frame of the projection screen.

I think you will hear an improvement to a room that has already been well treated.

I look forward to your impressions.

David Pritchard
Double sided 3-M tape is a good plan for fabric. You can evaluate if that is a good location. For long term placement I do like using a hot glue gun. I experience a further improvement when I more firmly afixx the HFT’s to a wall using the glue gun approach. I have them attached to the fabric headliner of my car using the glue gun approach❤️.
Hot glueing the HFT’s in place definitely increases their effectiveness compared to attaching with Blue Tac.

Absolutely correct reaction when even just one HFT falls off a wall. After installing two Synergistic Research Blue Wall outlets yesterday, I sat down to listen. First impression was “something is not quite right”. I had bumped a HFT and it was now on the floor. Reattached and the sound stage was now again wonderful.
I do a HFT count after anytime the room is cleaned or my system just sounds OK.

David Pritchard
sgordon1 and sbayne both makes  important points. The wide angle HFT has a significant effect on the soundstage and how you perceive the soundstage . My room already treated with HFT’s and the Atmosphere unit only needed one Wide Angle HRT. It took experimentation to find that spot but once found then sound was suddenly More Right.
The Synergistic Research FEQ mentioned acts to amplify all the HFT’s and ECT’s and with an added warmth to the sound- without loss of detail.
The Atmosphere unit transmits a wider pattern and more adjustable type of energy. It certainly is the state of the art product.
My Mother who is 95 , finds great satisfaction in her listening room treated with the full family of various HFT’s, a FEQ unit, and the Atmosphere unit.
A most remarkable sound room enjoyed by a most remarkable woman.
David Pritchard
Absolutely. I purchased a 1935  Philco console radio after finding out it was the same model my Mother listened to as a teenager. Very enjoyable indeed after restoration. 

Thank goodness we have learned how to improve digital music since the 1980's. Audio-grade wall outlets and fuses, The Synergistic Research ECT's and  HFT's,  Perfectpath Technologies Omega E-Mat and their Total Contact product all have greatly helped to make my digital systems sound most engaging and satisfying to listen to.

There is just no way my Mother could spin vinyl with her limited eyesight. But her love of music is not limited. With today's technology, she can stream music 24/7 on a system that is never turned off. Her PS Audio DAC has a remote that she can operate by feel.

It is most moving to sit in her room listening to a Benny Goodman song ("Your Father and I loved to dance to Benny when he played live") or notice her softly singing along to a Neil Diamond of  Karen Carpenter.

All of the above-named products are also utilized in her system.

David Pritchard
It really is an exciting time to be an audiophile and a music lover!
I do hope all on the Audiogon Forum get to hear some wonderful recorded or live music this weekend.

millercarbon:
Thank you for a most easy to read and insightful look at using the HFTs.
The HFT 2.0 will give some warmth and increased fullness to the sound, and it does not sacrifice detail in doing so. The FEQ is going to potentiate the effect of all the HFTs  in the room. 
I agree with sbayne on getting a FEQ.  Then as time and money allow you can add additional HFTs . If you over order the HFTs or pick a sub type that does not add to the sound you have 30 days to return them.
David Pritchard

 
They are very effective on multiple types of equipment and at multiple locations. They certainly have improved my video experience since being placed in the Oppo 203 player and on the ethernet connection.
David Pritchard
thyname::
I do think an excellent way to begin with using the HFT family of products is to order two packs of original HFT's and one pack of the HFT-2.0.
This approach takes into consideration  the Synergistic Research March special promotion of buy two packs and get one pack free.

This should give you an idea that they are indeed effective.
Yes you can place them on the first reflection panels.

folkfreak:
Thank you for the great suggestions on upgrading the power supplies to the Atmosphere  and the FEQ unit. I am trying this asap.
David Pritchard
The supplied Synergistic Research Atmosphere USB Wall Wart is rated at 0.5 amps at 5.1 volts. I have replaced it today a type folkfreak suggested which is rated at 2.1 amps at 5.1 volts. To see if I could get a further improvement I coated the body of the Wall Wart with the Perfect Path Technology Total Contact enhancer and also the prongs to the unit that plugs into the wall.

It will be a fun comparison.

David Pritchard
millercarbon:
Fantastic that you are using the Synergistic Research HFT speaker Kits. I also agree that they give an impressive upgrade to one's speaker's sound. Finally we have a way to fine tune our own speakers in our room.
 And it is nice that if you latter move or sell the speakers, the HFT Speaker Kit is removable and stays with you for the next room or speakers you own.
I do think they are worth trying on any speaker as they are easily removable and returnable if you do not like them.

The Wide Angle HFT's do have a powerful effect and so I had to experiment to find the optimal location. This was with all the HFT's previously mounted on the wall and on the speakers. 

For temporary placing of HFT's I prefer to use Blue Stick By DAP sold at Home Depot stores. The temporary adhesive that comes with the kit is fine but the DAP product is even better. After I am happy with all locations, I then used a hot glue gun to get a more permanent adhesion. I still can remove the HFT's without damaging the surface they are stuck to. HFT's that are hot glued on have an even greater sonic effect than when using the adhesive putty.


David Pritchard
millercarbon:
Yes the removable adhesive I like the best is called Blue Stick manufactured by DAP. Blue Tack is good buy I prefer Blu Stick after comparing both products.

I absolutely agree with you that treating the room acoustics with the family of HFT products gives impressive improvements to the sound.

 I also think treating the room should be done before an audiophile flips more components while searching for that special sound they desire.
