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.
