Hi Bob, I used to have Dynavector VX-1S, but now I'm with Ortofon A90. Re piping: it came with adj valve for the platter only. I modified piping so the valve now can adjust the tonearm air. Its more important to minimize the air flow for arm. Also it came with little noisy motor... I did replace the motor and now it completely cilent. For the table support I am using the FIM large spikes settled on acrylic platform on top of the small custom made rack. Cheers, Andrew
