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.

Removing the Tube traps to "try" will be a pain.
I was hoping that you had experience using the HFT's without any other room treatments.
I just received 15 of the Audio Magic "Bells".
Compared to the Synergistic Research HFT's these are much better. Better with deeper, wider soundstage. And the bass seems to be clearer and stronger.
So, with the 15 Synergistic Research HFT's I have I am using them as placement Four & Five and a few other places.

Oh yeah and the Bells are much less expensive than the HFT's.
I just made some home made HFT/Bells. These costs a couple of bucks and they sound better than the SR version.

If you look at my system picture you can see my copper version. The SR is in the center of the picture and it is slightly larger.
