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.

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.
I've decided to keep 3 sets. Decided not to use them on speakers, 15' high ceiling and open left hand side of the system.

Even with bare walls, my system sounded excellent. But it's amazing how these little suckers can alter the sound. I experimented optimal locations and in Level 2, installed one extra HFT in the center front wall above the center. So now I have 3 HFT on center front wall. It added height to the image and soundstage.

I've always prefer a lively room and HFT is the icing on the cake.
