Isolation platform under US 500 for CDP


I am looking for a isolation platform under US 500 for use with my CDP. My shortlist includes the followings:

- Silent Running Audio Tremor/less
- Townshend 3D Seismic Sink
- Neuance isolation platform

Are there others that I should also consider? What would be your recommendation?

Thanks guy for the input. The Neuance seems a highly cost effective bet but I would also consider SRA. I have read in these columns that SRA is having a new Squared series which unlike the VR is not component specific design. I would be more interested in this Squared series or the budget Tremor/Less rather than their component specific VR series, as I may get a new CDP down the road.

I have SRA Ohio Class Squared bases under all my gear, and they've provided an eye-popping improvement under each component I've used them with. I've tried a lot of the best of the best, including Grand Prix, Neuance, Bright Star, Aurios, Symposium, Black Diamond, etc., and NOTHING has yielded the performance improvement of the SRA. IMO, they're at the very top of the heap. And Kevin Tellekamp is one of the nicest and most honest people you could ever hope to meet in this biz. For your reference, the VR Series 2.0 is available in the new Squared configuration. Check out the following link: http://www.soundstage.com/revequip/silentrunning_ohio_class_xlplus2_followup.htm .
SRA Ohio Class XL Plus2 Equipment Platforms are up to ten times the cost of Neuance... is it really ten times better?
Happy Listening!
