When I first (re) substituted four Navcom pucks (no longer available) for the springs in the VPI, I heard significant improvements. Talked to Mike at VPI and he recommends these both over the stock springs and their newer Sorbothane inserts. Here's the kicker: Tappin on the shelf below I heard more breakthrough, not less.

Now - strangely - with the sandbox - if you rap on the shelf below - there is even MORE breakthrough - (I do this lowering the cartridge on a stationary record-then tapping/rapping) but it still sounds better - way better. Go figure.

I wish someone could explain to me that, even while the TT is more isolated in terms of its ability to perform - it responds more to the (relatively larger) vibrations. I suspect it has something to do with the microscopic level we're dealing here that has little or nothing to do with kinds of vibrations you cause when pounding on the supporting shelf but - I just don't know.

Obviously if you tried the same thing with a rigid suspension, cone mounted table - this would be even worse - I suspect, MUCH worse. Yet the energy that affects the music is "drained" awy or isolated or - whatever.

Would sure love to hear a plausible, technical explanation. Maybe - I'll just ask VPI depending on what I hear here.
