Synergistic Research HFT's


I acquired a ten-pack of SR's HFT room treatments and installed them according to directions just prior to last night's listening session. Easy to install using the blue-tack type of material that was included in the package. 

http://highend-electronics.com/products/sr-hft-high-frequency-transformer

The listening room already sported two pairs of Shataki  Holograms ... one pair in the front corners of the room and a second pair in the rear corners of the room. In addition to the Holograms, there are tube traps along the rear of the listening position. I thought I had my room problems solved with the existing treatments and I was satisfied with those results.

Enter the SR HFT's ...

I had my friend Robert over last night to help evaluate the changes, if any. I was looking forward to maybe a small improvement at best. I mean, what can one expect from little metal devises that stick to your walls ... little devises so small that one wouldn't even notice them unless they were called attention to?

Long story short ... we were hit over the head with astounding disbelief at the ... I don't want to use the word "improvement," because that would be an understatement. I'll use the word trans-formative instead.  Because, that's exactly what this tweak has done; its transformed my listening environment, and consequently my entire system, into an unbelievable music machine. 

The first CD I played was a private recording of Rachmaninoff's third piano concerto, with the L.A. Philharmonic orchestra during a Rachmaninoff piano competition. The disc features the winner of the contest on piano.  This has always been one of the favorite recordings in my collection. It transports the listener into the venue in a very natural way. This CD was burned right from the master tape with no artificial reverb or compression.   A good test for any changes to the system. 

Uhhh .... what I thought was a great recording transported us into the live event. Astounding to say the least.  How can such a simple tweak as ten little dots spread around the room have such a huge effect?  My theory is ... the sound energy coming from the speakers causes certain resonances at certain frequencies, and those resonances  excite certain areas of the room and smears the sound. The HFT's take those resonances out of the equation. That's my  theory, anyway. 

Here's the noted improvements:

1. A much more solid presentation at higher volume levels. Everything just seems to hang together better. 

2. Bass control: The best bass from my system yet. Very defined. The lower registers of the piano are a delight. 

3. Size of the presentation:  What I thought was a big sound stage before has been expanded in a very focused way.

4. Transparency: I can "see" much further into the presentation now. The audience noises,coughs & sneezes, the orchestra tuning up, the members turning the pages of the music, the conductor walking on the platform ... all there where a lot of it wasn't before. 

5.  Musicality: The correct tones of the instruments, which I've paid particular attention to in the system, were much improved. Strings, timpani's and the presence of the piano were all dead-nutz on. Amazing. 

6. 3-D:  A much more holographic presentation.  Good Lord, how much better can this get? So much more "air" around the performers. It really adds to the suspension of disbelief in a big way.

I could go on and on with our positive impressions last night, but I will echo what Robert said:  "This is your greatest tweak ever!"  "It sounds like you've improved your entire system." 

After playing a number of CD's featuring piano, we switched to the analog rig and played a whole variety of music ... from straight ahead jazz to Hawaiian music.  The expansion of the sound space, and the realism from analog and tubes with the new room treatment? Unbelievable. 

The ten pack of HFT's gets you to "level two" ... one more pack of five would get it to "level three."  Based upon last  nights results, there is another five pack in my near future. 

Are any of you other A'goners using SR HFT's in your room?  If so, please post your results here. I'd like to know if your experiences with these devises are similar to mine. 

Happy listening, guys.

I have the Atmosphere mini hooked up and the unit has been on for 24 hrs and I have to report that the results are pretty impressive to say the least and I haven't even installed the HFT's yet!!  

I have my system setup as a semi nearfield listening configuration with extensive ASC tube traps and room resonance control and it has quite pronounced imaging, soundstaging and bass agility without the mini but with the mini it is a much more engulfing experience. The most vivid attribute is the liquidity which still has me shaking my head as I have taken great care in my AC supply with that being high current balanced power, Oyaide outlets along with judicious grounding of components.

In my 35 years of being an audiophile, this is possibly the most profound upgrade I've implemented although I think a system/room that has been assembled with thought and research certainly will be beneficial to the Atmosphere's attributes, there is no doubt that any system will benefit from implementing one of the Atmosphere units to the point of being a major upgrade. 

Off to listen to more music...
Hey OP, how did you deal with the racks of albums, windows, doors, and rack when placing your buttons? Did you feel you compromised the placement because of those or would you say location is not super critical +- some inches?
nyame ...

Nope, no atmosphere or FEQ in the system. Just the SR HFT's and the room treatments I alluded to earlier.  For what they are, just ten little devises that you stick around the room, they are NOT subtle at all. A major advancement forward in my system for sure. Like my friend Robert said ... the best tweak I've tried yet. The improvement in the bass response is amazing ... and of course, everything else up the line is improved along with it.

Fascinating stuff!

Did you have an atmosphere or FEQ in the room when you got these results?
Inspired by this thread I spent an hour or so relocating my Atmosphere and 2 FEQs this morning. In my wide but not deep room I ended up with best results (most openeness and air) with
a) The Atmosphere on the ground center front, it had been raised on a Grand Prix Audio Monaco amplifier stand which actually did not help - maybe that the issue was it blocked direct sight to my ART resonator but in any case floor works best
b) Both FEQs mid way along the side walls, while this meant not having the FEQs connected into my dedicated power lines the location mattered more than the power
c) Both FEQs placed on the floor isolated by Les Davis’ thin constrained layer damping pads (these are very useful accessories)

The differences were pretty subtle but at no cost other than my time well worth getting it tuned in
folkfreak, 
" As it happens the Atmosphere does not replace the FEQ, you can and should use both. See the discussion here on how to set up (scroll down and ignore the haters)"

Thanks for the link. When I first installed the FEQ in the main rig, I heard  a definite improvement in my HT system which is two rooms away from the main rig so it seems the FEQ reach is quite a distance. Who knows, maybe the Atmosphere mini will affect my HT as well, we'll see but the FEQ is staying put in the HT system as the results are just too impressive.

I'll report out on the results once I get the Atmosphere mini hooked up in the main rig.
Thank you Davidpritchard and Oregonpapa. I agree, those who couldn't hear the difference might either be the system doesn't have the resolving ability or maybe just too old for their ears to do so. The same could be said for those who think cables doesn't make the difference.
s1nn3r ...

I second what David just said. You have a beautiful system and room. Love your floors too. :-)

I've gotten the same results as you, in that, the room just seems to get larger with each SR tweak I install.  Larger, but way more focused. The SR HFT's really opened things up for me. 

SR's demo at the  Newport show really showed what all of their products can do when combined together. Like I said, it was like a huge 3-D I-max theater picture of sound with the products in the system, and then it all collapsed and went away when the products were either disconnected and/or removed entirely from the room.

I can just imagine what the effects would be in a large home theater environment set up properly with a huge screen and projection TV with state of the art electronics and an ultra high-end speaker system.  

My business takes me into many very expensive homes that have custom theater rooms. These people need to know about the SR products for sure. 

How anyone cannot hear the improvements made by these products is beyond me. Maybe it has to do with the resolving ability of the system in the first place. I mean, one can put lipstick on a pig ... but its still a pig, right? And then there's that old sow's ear and silk purse thing. :-)

OP
s1nn3r:

Congratulations on improving your room's acoustics. Thank you for taking the time to display the photos of your room and system. By seeing the room one can really understand the improvements you have obtained.

Oregonpapa,

I was amazed by the demo at Axpona2016. Bought the Atmosphere, Black Box, HFT, HFT-X and HFT2.0 

The first test I did in my room is the Black Box. Bass is tighter with it. Then I added the HFT-X on the speakers and center of front wall between speakers. The detail of the music opened up. Then I added the Atmosphere. Imaging was so amazing. It made my room sound so much bigger. Then I added the rest of the dots. I'm blown away on how such small passive thing can change how our room sound. 
Its worth every penny IMO

Alan ...

I've done a demo for friends many times with the Shatki Holograms by taking them out of the room, then putting them back into the system.  The improvement is dramatic every time ... with the Shatki Holograms in the system. So dramatic, as a matter of fact, that I cannot imagine anyone improving the sound by taking them out of the system. 

How will "better speakers" solve room problems? 

OP
Put the tonearm HFT's on my Rega tonearm with Ortofon Bronze cartridge. Nothing. No audible change in sound. Had the Shatki holograms in my room for a year. Took them out of the room and the sound improved. Also played around with a RR-777. Worthless. You will get bigger changes in your room by moving your speakers around. I have setb up for myself and friends about a dozen rooms and gotten great sound for everyone without ever using any room correction. Buy better speakers. That will help the most
Alan
Oops. I don't count good. 20 HFTs on my walls, four on each speaker and a few on various USB cables...
The speaker - room interaction is one key to obtaining that special listening experience that I sought for many years. The HFT family (HFT, HFT 2.0, and HFT-X) have allowed me to dial in my room to a degree of music satisfaction that I never accomplished using the older technology of absorption and diffraction.

The addition of an Atmosphere Unit and FEQ Unit then further augments the beneficial effects of the HFT's. Visually the HFT's are not obtrusive which is vital in my house. Also in today's world where we are moving more often and renting more often, this system can taken down and then applied successfully to any number of future rooms. 

The Synergistic Research pictures on their web site and the suggested placement pictures included with the HFT's make installation straight forward.

I drink the HFT kool-aid too. I have 18 of the regular ones festooning my walls and speakers (3 on each--not necessarily located where SR suggests) and 3 HFT 2.0s. I "energize" them if that is the term, with an Atmosphere and an FEQ. I seem to get best results with the Atmosphere set to "Expansive" on most material. This is not to say that you need the boxes to get the benefit of the HFTs--they are amazing on their own.
As a side note, I just moved my FEQ into the HT system to make room for the Atmoshere mini in the main rig and am very pleased with the results, especially the visual acuity on my plasma monitor. Who would have thought the FEQ would improve that?!

Glad to hear of the excellent results you're getting with the HFT's. I will be exploring them myself here shortly as I picked up a package deal from the Newport show which consists of an Atmosphere mini, a 5 pack of the original HFT's, a 5 pack of the HFT 2.0's and a 5 pack of the new HFT X.

^^^ Nope, but that's definitely on the agenda.  That the PHT's, pronounced "POT."   They come in a two-pack. I'm going to try one on the cartridge and one on the turntable's junction box where the RCA connectors are. 

In the meantime ... the HFT room treatments are fantastic!
Have you also tried their little thing that goes on the pickup arm headshell?
