Best rack for non-suspension turntable?

What is your floor like? Seems like most folks with non-suspended tables get excellent results with anything that is rigid. Avoid direct placement on MDF. I've built a stand with integrated sandboxes and 2 1/2 hard maple shelves. Works almost too well, but I think any thick hardwood shelf would work. It is possible to over-damp and adversely affect dynamics, which is what happens with my setup when I allow the 'table spikes to embed into the maple shelf. Whether this is due to the sand or maple or the combination of both I don't know. A few sheets of aluminum and steel under the spikes brought the leading edge transients right back.

A more cost-effective solution than the Halcyonics, with comparable performance, is a
Minus-k BM-8 isolation system ($2500). My recollection is that the WTC is not a high-mass design (< 100 lbs) and therefore well within the payload range of the BM-8. I've had one for about 6 months and have been enormously impressed with this isolation system and the improvements it has wrought from my VPI TNT.

i agree with your wife

Mike,

Have you considered, tried, and or compared the Minus K with the Halcyonic shelves?

I have been reading/thinking about getting the Minus K for my 150 lb Teres table.

check out what Lloyd Walker has done with his table. There should be a link from his site to an in depth review where it is described how he has it on a thick wood slab with a bunch of sorbathane pieces between that and the shelf. Loading the TT with good cones such as the Mapleshade Ultimate Triplepoints or Walker Valid Points into a massive hardwood slab suspended by sorbothane might be a simple, affordable and effective choice.
