As I wrote last time, I have now tried the HFT's on my friends during a music listening session we had this weekend.
After listening for a couple of hours, I set up a level 1.
while I was doing that, jokes ran thru the air like pouring rain. None of my friends was expecting any positive effect from theese small things. I was doubtful myself, still wondering if I had just imagined my earlier observations.
It took about 10 seconds. Then I heard the same thing as I had heared before.
The guys jaws dropped and they sat still without talking.
Wow.
We listened with the HFT's in place with different music, mostly rock and blues.
When we took them down, there were no question. The soudstage, the calm sound, the differentiation of singer and instruments just dissapeared.
I can't explain it, I've had my doubts, but everyone I had tried it on has the same reactions, without me telling them what I think.
Strange!
I have now level 3 in my room. Gradually better, but nowhere like I found the first level.

I just ordered two sets on the Free Trial. Can't lose.
Look forward to the results of your trial.

Glad to hear you're enjoying them Tero. I am.
Jim, please let us know your thoughts.

I do have one concern regarding installation when they arrive. According to SR's installation guidelines several of the units will be installed between my GIK Art Panels. I am wondering if the units sitting between 1 1/2" deep panels will limit any of their supposed benefits.
In the first pack of 5 the only problem location will be the one centered between my speakers. That location is between to art panels about 5"-6" inches apart. I will have a slight problem with three locations with the second set of 5. The two side wall and the location behind my seating position could also be impacted by panels. We shall see.

Jim: looking at your avatar, I'd venture that one could be placed above and between your panels by a few inches. The ones to the left/right should be matching height. The one dead center at approximately tweeter height will have to sit in between the panels. FYI my HFTs at my first reflection points are pressed onto my panels. The tack will have no problem holding them on a panel if needed.

Thanks for the suggestions. I will see what I can do.

I called sr directly the guy from the setup video helped me thru the specifics of my room setup. He was charming and really helped me avoid doing a sloppy setup. Call them

Well, well, this is a very interesting thread. I must say that I am quite skeptical about the ability of such a product to produce physical as opposed to psychological results, but I think additional scrutiny is warranted before it is dismissed out-of-hand (if for no other reason than the fact that reputable forum members are experiencing positive results). To start, I think there are a couple of misconceptions that have been discussed regarding both the product and the way it derives its results that deserve comment.
Let me start by saying I, much like Gary, believe strongly that science is the foundation of changes in the physical world and only such physical changes will be measured consistently in blind testing. On the other hand, I don't believe that all psychological effects spawn from emotional insecurity, they can be as real as physical affects as long as we are ultimately talking about affects (be they physical or psychological) that drive an emotional state of mind; however this latter point is not my focus because I, much like Gary, prefer to know (or at least be confident) that my state of mind is more influenced by the physical world than the alternative.
So here is my main point: the way I have read the reviews on the HFT/FEQ, I am not sure the following posts are even accurate. So, as a matter of science, I don't believe they provide a basis to even begin an appropriate evaluation.
My understanding is that these little HFT gizmos are designed to be active and are supposedly tuned in a manner that causes them to be "excited" by ultra-low frequency RF pulses released by the FEQ. This excitation in turn allegedly causes them to act like tiny high frequency transducers that transmit "sympathetic resonance" which, again allegedly, clean-up high frequency harmonics and cancel harmonic noise in your listening room.
Hmmmmm, so at least we now have a theory involving a scientific concept that might be theoretically possible in the physical world (i.e., the use of radio waves to activate a tuned transducer which generates high frequency sound waves that cancel bad stuff). That said, now it seems a reasonable discussion could be entertained about the plausible scientific likelihood of such a contraption working. To me a few questions may go as follows:
1) How could a constant frequency band RF generator trigger the transducer to resonate at the exact right high frequencies to cancel the bad stuff for whatever music is being played?
2)Is it even possible for RF signals to propagate resonance from a metal shape regardless of how its tuned?
3)Does anyone have any negative experience with the HFT's? As an example, has anyone experienced a complete failure of the HFTs to improve a room?
Respectfully to all,

I ordered two packages of the HFT gizmos. Late yesterday I installed the first package (5 pieces). As suggested I placed one on the front wall between the speakers, one on each side wall approximately at the first reflection point, One a the ceiling about 1/2 way between my speakers and my seating position and the last one about one foot above behind my head on the wall behind my seated position.
I plan on leaving them as is for a period before removing them to see if I hear any differences. My initial thoughts are that there appears to be a ever so slight more relaxed nature to the sound.
I am not ready to make any judgements either way. Within the last day I had some work done on my electrical service when I had a whole house back-up generator connected which necessitated some rewiring (removing the sub-panel for my ad-hoc unit) and making my main box a sub-panel. I am also back to my Momentum's and Ayre unit after auditioning the Momentum Integrated.

Jim, Are you combing the HFT's with the FEQ to achieve the "activation" by RF pulses emitted by the FEQs?
Also, did your electrician lay new grounding rods for the generator panel? Normally they do (at least they did for mine) and this can reduce noise floor.

No, I did not purchase the FEQ.
I am still grounded near where the meter is located outside my home. They also added a second ground within six feet of where my water pipe enters the home per code. Since my original panel became a sub panel that required rewiring to separate the neutrals and grounds. They also removed all of the additional wiring that was required to connect the Emergency Transfer Power System sub-panel I used when power was lost in the past.
Hello Jim,
Was that really the suggestion for the first set?
Have you not tried the "level 1" positioning as suggested in the instructions that came in the package? For me that was the start of an exciting journey.
I have up to level 3 with the FEQ.
not finally installed, I think there are some improvement to do yet.
