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.

Interesting stuff. Lots of people and press at the event suggests the demo clearly demonstrated that the product was of substance. But as with most audio, especially in this arena of acoustic spatial add-ons it is not only system but room dependent. I'd only give this a go with the assistance of trained dealers who've had both experience in their own shops and with customers. However, if I was a dealer, I'd better feel it worth the time and effort to set up this product. Given its relatively low cost (at least for those of us with rather expensive gear) it certainly had better benefit nearly all environments, or it won't do well going forward. But I'd certainly not discount its affects. There's much we don't really know or understand about what the ear/brain system captures, and the psycho acoustic effect it has on our listening experience.
Stevebythebay, at the RMAF, I heard a Bose radio sound different with and without these devices. Is that proof of "substance?"
I tried 5x HRT on my home theatre in my living room. What I heard was an increased low bass and separation. I removed them and the magic was gone. Yes the effect is obvious and tangible (for the bass shaking the floor). Rushed back to the shop and bought more for my audio room.I haven't install the FEQ though.
Yes, even 5 HRT units will improve the sound. As more units are placed the sound becomes more detailed but with less fatigue and with a much more satisfying sound stage. Most rooms are optimized with 20 to 25 units. The Frequency Equalizer (FEQ) significantly lowers floor noise and improves detail through the audible spectrum.

I continue to be very satisfied with how both products have improved the sound in my two listening areas. One is audio only and the other is home theater.
