Halcyonics under my tt. Wow

I've talked to the folks at Halcyonics, and they say that the upper limit of operating frequency is ~ 200Hz, which makes sense, because active vibration control relies on a feedback mechanism, where time delay is inevitable between vibration sensing and compensatory actuation.

What this means is that if we attenuate/eliminate vibrations under 200Hz in our audio components, great sonic improvements can be expected.

Wonnjun, I inadvertently got my turntable vibrating back and forth yesterday and the Halcyonics sought to dampen the movement. I have notices that women's voices, at least in my system, excite its correction more than men's, which makes your new information striking.

The Micro series can display the four of the vertical sensors or the four horizontal sensors. At the Rocky Mountain Audio Fest which in between two Interstate routes, they were quite active. When I move about on my suspended floor, they are quite active also.

Tbg,

Thanks for the report. I have been considering the Halcyonics. I have a 140# turntable (Galibier Stelvio) sitting on an Equarack with a Grand Prix Platform. The Equarack made a huge improvement in the sound of my system. How much impact would you anticipate with the Halcyonics? Would I have to use a separate stand for the turntable?

Thanks in advance for your input.

Jazdoc, I fully expect you would hear a great improvement. I had my Shindo Labs on an Acapella Silencio base with the special feet I bought for the Shindo. The base was on a Mana Reference rack. It was already well isolated, I thought. I am on a second floor, however.

If the Galibier Stelvio on top the Halcyonics will fit or allow you to reach to put on a record, I suspect your existing rack would work.

I demoed the Halcyonics today merely turning it off and listening and then turning it on. The guy's jaw dropped. Once before I had a friend up and we listened for two hours before I noticed that the Halcyonic under the cd player was off. He cursed me as the improvement moved the sound, he said, from good to the best he had heard from digital.
