Transducers like ECT from Synergistic Research

Everywhere. Like my post above says there are only 2 places they haven’t made a nice improvement. All the other places they work about the same. This includes being stuck somewhere on the outside vs being stuck on a cap or board inside. It seemed logical that directly on a board or cap or transformer would be better than just stuck on somewhere outside. But not that I could tell. Sticking them inside seems a lot of extra work for no extra benefit. You can try it, you never know.

There are three on my tube integrated, one between the rectifier tube and the power supply transformer can be seen in images #2 and #3 here https://systems.audiogon.com/systems/8367 The other two are between the output transformers and power tubes. Tried directly on the transformers, this (between transformer and tubes) was slightly better. Tried them inside, huge amount of work to realize it was slightly worse.

Also nice having them on the outside you can move to another component. Like as noted in my post above the improvement watching video off my laptop is pretty obvious. So for movies I pull one off my turntable motor and stick it on the laptop.

In your system it looks pretty obvious to me, five components, five ECT, one each.

First ECT went on my turntables motor pod. Not anything like where SR recommends. Yet I heard improved detail and dynamics, a bit less grain, better image focus with more air and greater depth. Not by a huge amount but impressive for just one. ECT are supposed to be Electronic, but I have two on my tone arm because they work even a little better there than on the motor. It might seem the best location would be inside components and even directly on things like transformers or caps, but I did not find that to be the case. Some I left inside because its such a hassle moving, opening up, reconnecting, hardly worth it when by then I know its going to work either way. Which is the main point. As Pritchard says you do learn where they sound best. But the differences in most cases are pretty small, or at least the difference between where is small compared to the difference between using or not.

They are so easy to place and remove, and the changes are so immediate and easy to hear, that I’ve tried them all over the place. The only two places I couldn’t hear a difference was on my iPod, and on the HDMI input on my projector. Well, in fairness SR recommends locating them on the output not the input.

Which leads me to the most amazing place ECT works. We often watch movies with my MacBook Pro connected to the system. When I placed one ECT close to the HDMI and audio outs on the Pro my wife immediately- and I mean immediately like before I could sit back down- said WHAT DID YOU DO???!?!? The already good picture took on an almost 3D appearance it was so clear and detailed!

Yes, just one ECT did this.

Oh yeah, highly recommended.

Ditto PHT, and all the different versions of HFT. All are additive, there seems to be no wrong order to do them in, and together they will transform your system, especially in terms of helping your speakers and room to disappear.
