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.

Even though I have four Shatki Holograms (one in each corner of the room) and a compliment of Tube Traps in the rear, a ten pack of HFT’s transformed the room and finally completed the room treatments. Great product and highly recommended.

Bit surprised by this, the UEF dots made quite an impact.  I borrowed 6 HFT's for the wall behind my speakers (Magnapan 1.7i's) and they made a small difference in soundstage depth (made a huge difference on my friends system though).  Tried a 10 pack of UEF dots and the difference was astounding.  Added 5 more and even more imaging precision and timbre accuracy.  Has anyone tried level 4 and 5 (20/25 dots)?  Do the improvements continue?
The Wide Angle version HFTs may provide a short cut for you, and
result in better sound.  You can really "dial in" the sound!

Are these an option for you?
If they were available in the beginning, I think I would have saved 
time and money.
