Synergistic Research HFT + FEQ


I heard this tweak at RMAF and brought it home on a 30-day free trial. Unfortunately it turned out to be a real system killer. I had 20 of the HFTs and tried them with and without the FEQ, using a ladder to put them up and take them down repeatedly. I couldn't believe how awful it was. Made it hard to enjoy my otherwise excellent ~$45k system.

I had a similar experience with their Quantum fuse. Never did trust anything with "Quantum" in the title. HiFi Tuning Supreme fuses, on the other hand, made my amps sound significantly better.

The cost for these little gizmos seems outrageous considering how light weight they are. And based on past SR history they will soon be replaced with a mark 2 version.

But, I have 2 sets on loan and they do seem to expand the soundstage. However, sometimes I think the sound doesn't sound quite right. I just can't quite get a handle on it.

I did find that placing them slightly higher is better in my room than the lower height shown in the directions. And I think for my usage, 3 sets would seem about right.

So, I am still in the undecided testing stage.
I have been curious about the HFT/FEQ due to the challenges I have with room dimension and acoustic treatment options. Let us know your results Knghifi.
As you put up each group of 5 HFT's you will hear the soundstage expand and then become increasingly more rich and detailed.
Still UNDECIDED sticking them on my TAD E1s. Yikes!

I'm remodeling my home and walls are bare so hope these will improve the sound until it's done. Room is 33'x25'x15' and currently system sits on half the long wall. Left hand side is open with no wall so will be interesting.

I finally decided to buy them after watched Peter Breuninger video and have respect for his opinion.

Two sets of HFT's mainly demonstrate that they have an effect. Like you I have a QOL unit in my listening room. I sincerely hope you will order three additional boxes to really tune your room acoustics. With two sets (10 of the little bullets) of HFT's my soundstage changed but lacked focus. AS I put in the next three sets of HFT's I heard a real change for the better. As you have heard, the locations suggested in the instructions are only starting points. With additional HRT's in place you might move the units up or down from where they are now.

I am finding the combination of the HFT's + FEQ unit with the BSG Technologies QOL unit to be sonic bliss.
Well, I guess I am giving it them a thumbs up.
I went ahead and purchased 3 sets. The 3rd set will arrive later this week.

How the heck these little items actually do something is a real mystery to me. But once you try them, your gonna keep them. Just don't tell the wife how much they cost each...
