VPI-19 feet

I replaced the stock feet on my VPI mk4 with BDR mk4 cones. I also had J D Casser at Black Diamond grind down a set of mk 4 cones so tht the tip is gone. I replaced the plastic caps that come on the 4 springs with the cones, so that the plinth sets on the cones. The difference was dramatic! I know that sprung TT's are supposed to be very warm and lush, but after doing this, my TT is very dynamic and detailed.

I use the threaded aluminum cones in place of the stock rubber feet. Cones rest on brass Audio Points pucks, sitting atop a Black Diamond shelf. Black Diamond shelf sits atop an Arcici Airhead. Have not experimented with other combo's (admittedly I should) but this setup is doing a nice job.

I've decided to go with the brass feet from Audio Points.

The VPI-19's stock feet are a thread size of 10-32, a 3/16" screw size. The Audio Point model for this is the 1.0AP-F, $20 ea.

My 19 uses a pressed in steel T-nut for the feet. I'm giving thought to dusting those, and going with an upsized brass insert - at least a 1/4-20. That way, I'll have a larger screw, and brass-on-brass...

The cones are HORRIBLE once you know what the VPI can sound like (or not sound like). I still use the stock feet but have a Townsend Seismic Sink under them, totally removing the vibration problem. This setup includes the VPI IV modified, SME IV modified, SAMA, Lyra Beta all on a 3/4" slab of granite in a rigid steel frame stand. The cones transmitted or reflected back the vibration with the stock feet do not. DO NOT USE THESE CONES. I robbed myself of good sound for several years with them.

Mr Fleschler that's very interesting, however I do have trouble understanding something about your setup. With a seismic sink under the TT footers, what functions do the granite slab & steel stand serve? It seems like the Townsend would isolate everything below it (the granite & stand) from the turntable's base so effectively that it wouldn't seem to matter very much what the seismic sink was resting on top of? What am I missing here --- anyone?
