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 wonderfull fact about the HFT - FEQ units is they are complimentary and yet have nice effects on their own.
The FEQ Unit works on lower frequencies than the HFT's. The music becomes more full and balanced. Also and quite important is the it's effect of lowering the floor noise. Less congestion when multiple instruments are playing.

Adding the IPC units "moves" the music more into the room. I am over the top happy with the interaction of the HFT + FEQ units and the IPC Acoustic Energizers

The QOL unit adds musical information to the speakers.

The Acoustic Revive77 (Schuman Resonator) works well and there is a sense of "loss" when I turn it off.

So in my system I am not hearing an over processed sound. Instead I am hearing full glorious music.
Synergistic Research XOT's have been ordered and are on the way. Should be here Thursday. Since my speakers are biwired I ordered two sets. I will try a set on the mid-high terminals, a set on the low terminals, and then sets on both terminals at the same time.

Should be fun and educational.
I am happiest with the Stein Speaker Match, which
integrate the top and bottom of my biwired Martin Logan Prodigys
as never before. The XOT did nothing for me,
but at least I gave them a try. (It was not a close comparison...)
Sgordon1, Thanks, for sharing your experience with the XOT's.
David, Look forward to your opinion also on the XOT's.

What I recently found was placing an Audio Magic PEA stuck to the back of the speaker cabinet just over the crossover really made a significant improvement in sound quality of each speaker.
