ELP laser turntable - any comments?

From a spec point of view, the Minus K passive isolator should be able to go head-to-head with the Halcyonics. The Minus K achieves 50 dB isolation at 10 Hz compared to the 40 dB of the Halcyonics. Also, the Minus K has a 0.5 Hz resonance, and the Halcyonics starts isolating at 0.6 Hz. For building isolation, the Minus K can handle fairly large horizontal and vertical displacements - 0.5 inch vertical and 0.75 inch horizontal travel. I'm curious what travel the Halcyonics has. Is NABS open to doing an AB comparison of the Halcyonics versus the Minus K isolators? I use the BM-1, and in my own testing have found that it outperforms air. It would be interesting to see how it stacks up against active isolation. How much does a Halcyonics isolator cost?

User, the 17.6" x 16" Micro 40 is $7890. I cannot imagine that anything like a .5 inch vertical or .75 horizontal travel could ever happen with the Halcyonics. The correction would have done whatever it could with even a fraction of this.

I am not in the least surprised that the Minus K outperforms air, such presumably as the Vibraplane and the Townsend Sink.

Tbg...If your TT moves 1/2 inch vertically, and 3/4 inch horizontally, I submit that you have best evacuate the house, especially if you live in California! As to specs...40 dB and 50dB are not significantly different in terms of real world effectiveness, and may be dependent on exactly how the number is measured. Same goes for 0.5 Hz vs 0.6 Hz. A side-by-side evaluation would be interesting, although I bet that either one would take care of the typical home floor vibration. In my experience acoustic feedback to the vinyl is the predominant problem after even minimal attention to floor vibration.

Eldartford, just think if the unit could keep the record playing in an earthquake!

What seems to be an interesting difference between the unit is that with the Halcyonic there might not be a resonant frequency. This may make no difference. At any rate I hope to get to try one in August on returning from Alaska.

NABS welcomes comments and inquiries regarding Halcyonics’ products and encourage the audio community to conduct objective A/B testing. We will do our best to facilitate and support any inquiries and or attempts at testing Halcyonics platforms. We are convinced that audiophiles will be pleased with the results of the Halcyonics platforms much in the same way as the hundreds of research laboratories around the world who have been using Halcyonics’ products for almost a decade. What makes the audio hobby so unique is the way in which different manufacturers approach similar problems in different though successful ways. Minus K and Halcyonics are examples of two completely different solutions for the same problem. No doubt, the Minus K and Halcyonics solutions go well beyond the standard vibration tweaks and platforms offered here on Audiogon.

In our opinion, the Halcyonics platforms offer some unique characteristics not found in any other platform marketed to the Audio community: (1) their unique combination of low profile, flexibility and performance; (2) their ability to provide ongoing feedback on vibration to users not only from monitors on the stands themselves but also through software that comes with each unit that provides a virtual oscilloscope to measure vibrations and assess the least resonant location for placing a stand; (3) their use of active vibration control which isolates vibration caused when the user touches the equipment; (4) their ease of setup – it takes literally seconds to setup the stands initially and no tuning or adjustments thereafter; and (5) their vast adaptive range of weight capability – the Micro 40 handles weight from 0 to 220 pounds, vitiating the need for different platforms should your equipment change, are just some examples of how our products differ from others on the market. Each user should examine their own priorities and needs in considering the value of Halcyonics or any other vibration isolation products. We look forward to participating in an ongoing dialog on this and other advances in audio technology.
