Thanks again Pryso,
Yes you're right. The shelf is certainly 'mass' loaded but with the actual turntable isolated on spikes, there is theoretically a de-coupling from this 'mass'?
And don't the adherents to massive plinths require direct 'coupling' via bolts or screws? Although I do recall someone making plinths who advocates that the turntable merely 'sits' on the plinth without mechanical connection?
