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?

Audiofeil, the change in sound of the turntable spinning for a while is probably due to the lubricating oil in the bearing warming up. At least, that's my semi-educated guess.

I can't say that this will be true of all turntables, but it's true of my Galibier.

Yes, I am truly nuts...

I wanted to see how little I could spend to create an isolation platform for my amp. I did research on microscope platforms due to their similar need to stop vibration. There were a few manufacturers who used an inflatable bladder or series of bladders to stop vibration. I think they feel air and soft rubber doesn't transfer vibrations very well. So, I had my granite counter guy cut me a platform (20"x18"x2") and I used bubble wrap (approx. 1" round bubbles) under it to isolate. The bubble wrap is fairly strong when you use a 20"x18" sheet and supports the amp nicely. So far the bubbles have not leaked or popped after 6 weeks but I am checking daily. I am sure I could use wood instead of granite but my goal was low cost and the granite was free. Besides, the black granite looks good. My next step is to use racket balls (like Ginko balls) under the granite to see how they work.

Any thoughts or hints?
Stringreen,

Thanks for the info. I have not used Ginkos so I was not aware they were solid. My comment on them was more of a visual discription.

The microscope platforms seem to go on the idea that the least amount of material between the platform and table provides the smallest pathway for vibration. Thus the hollow bladders. I have seen audio racks with opposing magnets to elevate the platform and literally eliminate any contact. The hollow racket balls may be more in line with their theory than the Ginkos. Since this was designed as an experiment I am open to trying different designs such as racket balls (or any other isolation bridge).

I notice that you have moved to AZ. Welcome. We can always use more quality Audiogoners!
