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.

Ozzy, I'm impressed with the DIY HFT's! They look cooler IMO. I don't see any bells on Audio Magic's website. Are these prototypes? I had great luck with the AM PEA's and appreciate your observations last time. Works well with the ZX Pulse Gen (have this on an Oyaide 079 plugged into the ar2p-to). I actually found the Akiko Tuning stick worked on my system (I cut the AC plug off and placed it on one of my amps negative terminals). I came across your findings recently on the WA Quantum fuse chips and now I'm waiting on those to come in for the SR20's I have. Too bad that power chip didn't work on the audience! I tried an Acoustic Revive qr-8 on the top of it with a friend. Insane soundstage effect and precise imaging, but sadly the highs overtook the other frequencies and introduced harshness. On his system damping the top of the P10 has a nice all around effect (Entreq Vibb). Not sure if HRS plates will do the same (the thicker DPX model is awesome on my source). Next up, SR RED fuses!
Ozzy, nice stuff! My friend and I experimented with the HFT's on his system. They were very effective once several packs were used. With just one pack, the height of the soundstage (or stage position) went up too high. Voices kind of on top of you. Tone shifted towards the highs. With many packs around the room they did expand soundstage and provide higher resolution and I think tone went back to normal. Results will vary, room to room, system to system. I'm reluctant to try HFT's with the tall Magnepans. I don't think they improved tonal qualities, so it's interesting that yours do that! Copper is likely a better material. The AM kit is interesting, but still a bit of money for me. My friend also has the FEQ. All around amazing product, well worth the cost! To me it was similar to the effect of the aR2p-TO, in terms of resoltion, dynamics and soundstage. But the FEQ goes about this in a very relaxed way. My friend made his own plug in cable out of silver wire and an Oyaide 004 connector. I was shocked at the improvements. Even clearer, more soundstage/resolution/bass, no ill effects.

There's a damping product from a European company called the "Entreq Vibb Eater." Much like the HRS damping plates they are placed on top of a device. On the P10 it really helped all areas. The Vibb is a basically a leather pouch with several pounds of damping sand. It may have some EMI properties as well and pebbles, I'm not sure. The HRS plate was tremendously effective on top of my Oppo 105. It took the player to a whole new level, while somehow taking away much grain and harshness at the same time. I bought one more plate, but have yet to try if a second will add further improvements. For the money, I haven't come across such an easy effective tweak (aside from HighEnd CC's 75ohm terminator, best $20 bucks ever spent). I haven't tried any damping material inside of my components yet. I was looking at the Fo.q stuff (but the HRS plates cost just a little more). I'll take a look at Herbies offering! After experimenting with the Acoustic Revive QR-8, I feel their's got to be an effective damping product for the audience aR2p-TO. I'm also looking for a way to dampen all my Oyaide 079 connectors.

The SR Red's are a bit pricey but I'm considering buying. Unfortunately, I can't find what they actually changed. I did find out that it should sound similar to the SR20 with an increase in resolution and lower noise floor. I looked closely at the pictures and it appears the end caps are the same. So changes are likely inside the fuse. I wonder if SR added damping filler like Furutech... Has anyone tried one of these yet?
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?
