Tweaks that convince others you're truly nuts...


The challenge always is to pay attention to what you hear and to trust your ears. Over the years, our listening room has seen the passage of a range of tweaks, and some have stayed because we're convinced they make a positive difference in our system and our room.

The most recent visitor that seems quite likely to stay are the Shakti Hallographs. And I never would have expected this. Two local audio friends had already listened to these sample units in their listening rooms and didn't hear any change whatsoever. But in our room, on complex large scale orchestral music, we heard an immediate and very positive improvement in the soundstage, in image specificity, and in the clarity of the upper mid-range and treble. The soundstage, already good, simply opened up and increased in apparent size, room boundaries became much less noticeable, and a troubling subtle refraction from the exposed brick fireplace and equipment rack behind the speakers disappeared (hurray!). How can something that reminds me so much of cookies dipped in chocolate make this sort of difference? Trust your ears.

(The Shakti Stones, on the other hand, made a quick departure from our system - killed the sound.)

Walker Audio's Reference High Definition Links (HDLs) were an earlier visitor to our room that were not permitted to leave. These delivered a surprising improvement in clarity to a set of speakers we thought sounded pretty doggone clean and resolving (Avalon Eidolons). Another one of those 3% improvements that cumulatively start making major differences overall. Fortunately, we never have to explain these because they fit inconspicuously at the speaker terminals mounted underneath the Eidolons.

Walker Audio's Talisman has become a regular part of my vinyl regimen. It sits to the left of the turntable and draws no attention until the LP playing ritual starts. Seeing me wave this thing over the surface of an LP creates immediate consternation in visitors, if not outright laughter. Yes, it works, we hear the difference, and we now use it with every LP side we play.

Nipper strategically positioned behind and to the left of the OTL amps... No, doesn't make a sonic difference. Just a fond memory of the friend who gave him to us. And after all, it is the friends we make through this hobby of ours who make all the difference.

So what in your room results in incredulity in your visitors?

Shoot, when I recommended to a guy to fill the hollow tubes of of steel speaker stands, he was incredulous and kept saying, "Really?"

I kept trying to explain to him that resonances are the enemy of clarity and linearity, and having been a percussionist, I knew that hollow metal tubes act like chimes. And that filling the tubes with sand squelched the resonances.

To which he again said, "Really?" This is a $3.49 tweak.

Six months later I talked to him again. He'd bought the sand, but had never filled them yet.

Really?
Rushton, I agree with all your tweaks, all easily heard in my system. Oddly enough, you and I seem to be two of the few that don't like the Shatki stones.

Of your list, only the Walker HDL is controversial, and only then because there are speakers they don't work well with. Kharma Exquisite immediately comes to mind.

I got terrific results with Walker HDL on both my Dali Megalines and the Sound-Lab Ultimate before them.

A dozen tweaks that have proven effective for me:

(1) Isoclean fuses (and likely Hi-Fi Tuning fuses when I get them installed)
(2) Cleaning ALL your connections, then treat with contact enhancer (I like Caig).
(3) Add weight on top of (some) equipment. Buy or make your own and see.
(4) Audio Prism Quiet Line (or same effect via other brands).
(5) Best quality jacks and speaker posts. OFC Vampire, Cardas, WBT or whatever.
(6) Precise load for your phono cartridge (and the best resistor for the job).
(7) Keep equipment apart both horizontally and vertically to reduce interaction.
(8) Dedicated lines and good quality AC plugs in the wall and on your AC cord.
(9) Acoustic treatment on all surfaces, some as diffusion, some as absorb.
(10) Texas Instruments EMI shield. I have in wall and on turntable.
(11) Grand Prix amp stands
(12) Most isolators and feet. All audible, some help, some hurt, they all "work."
First, the Acoustic System Resonators. They're resonators, just as your Hallographs. When I first got mine, I brought one to work and the head Metallurgist saw it. I told him of the designer's claim, and he told me that that's exactly what those metals do and there was no voodoo behind it at all.

Second, the Acoustic Revive RR-77 low frequency generator. I had to remove it from my stereo room because although it worked really well, after ten minutes my ears always started ringing to the point that I couldn't enjoy the music. Something in that room was getting excited and resonating, but I have found it yet. However, in the bedroom I've never had better nights of restful sleep.

Hi,
This is a tweek from the legendary Bob Fulton for you analog guys. Tune your turntable mat. Bob used to sell a flexible blue mat that reminded me of sorbathane or some sort of soft, spongy plastic. It had a small notch on one edge. We would also make a small mark on the platter itself so we knew where we started. According to his directions, one should rotate the matt around the spindle by quarters and listen for the best sound. Then when one found the best sounding quadrant to place the mat, one would cut that quadrant into eigths find the best eighth and then if you wanted to narrow tune it even more down to the best sixteenth. We tried this tweek on Linns, Sotas, Denons, Aristsons, and Oracles. There was always a best position for the mat where the midrange in particular snapped into focus. We also experimented with this phenomena with the Oracle mat and latter the Sota acrylic mat that became available. There was always a "best" mat position and when we tweeked custys turntables this was one of the last things we performed. Try it out and see what you think.
Good listening,
Steve
Fun thread, Rushton.

We've had visits from a local 'phile and former TAS reviewer. Among the tweaks he's brought along to try were the Shakti Hallographs. Cookies dipped in chocolate indeed!

We all heard the differences they made, but in our room/system the dominant effect was to disrupt the time relationships between various high frequencies. Some ears might have found it smoother, but the three of us agreed that - in this room - the effect was more confusing than anything. That old YMMV strikes again.

On the positively positive tweaky side, our visitor suggested unplugging various devices around the house, including the microwave oven in the kitchen. It's on a different circuit than the one dedicated to the stereo, but even so there was a notable reduction in HF haze. Unplugging the TV (which is on the same circuit as the stereo) had a similar but smaller effect. Weird.

Our nutty tip? Unplug the microwave!
