Turntable isolation platform Recommendations?

I know probably very few people want to hear this but active vibration cancellation platforms like Halcyonics are a revelation to vinyl playback.  
It works exactly like the scanning electron microscope before and after images shown to illustrate how they work.  Turning the platform on seems to “focus” the sound just like it does for images.  Even off, I believe the platforms give some some benefit in very low frequencies. 
I have a bunch of active vibration platforms which I have to get into service.  They will come in handy once they start building the second Ave subway in my area of NYC, and vibration will be pretty bad as I’m probably 150 ft away from the dig.  

Off topic, but I couldn’t help respond to  myjostyn (Jim?) comment.  I also run a C4S - a Targa from 2010 with the hatchback that makes the car practical for work or a Costco run.  I recently had the entire car wrapped in paint protection film after having some panels repainted since I want to keep it for a long time.  Sadly here in NYC there aren’t any places to open it up, save for the occasional on ramp turn at night.  

Has anyone tried AG Lifter from New Zealand My friend has tested a rack with Clearaudio Innovation turntable on top , amp w power supply below and say's its shocking in improvement, and he is very conservative guy He said it's like having a complete system upgrade

But along with Minus K, only for the wealthy

Interesting to see this thread come live again. As it was the thread that made me think a Silent Running Audio Ohio class isolation platform would be a good decision for my contemporary Linn LP12.

I ordered one about 6 or 8 months ago. It was an excellent purchase. Owning an VPI Aries for a couple decades… I liked my new Linn LP12.. Akurat with a Koetsu Rosewood Signature cartridge… but it lacked the solidity in bass. The “liveliness”, to me sounded like the sound image was flitting around at very high frequency… instead of dead on anchored to one location… subtle but a meaningful problem. The SRA Ohio class +++ or what ever anchored the images and solidified the bass. A really great addition. Highly recommended.

 

Since then I upgraded the Linn sub chassis and tonearm to the Klilmax level. Wonderful turntable… wonderful isolation platform. Thanks for your input. Now my analog end is really competitive with my digital end. They are both so compelling, it is hard to decide which is better…. Great problem to have!
