Jamie, have you tried bypassing the feet on your tt with wooden cones? I have my PTtoo on 4 wooden cones, sitting on a bamboo board with sorbothane between the board and the hifi stand. I have recently purchased a Technics SL150 and I am going to try 3 stillpoints (only have 3) and don't have any more cones, between the tt and bamboo board. My theory is to get rid of unwanted vibration in the tt, I may be talking nonsense though.

I think that either coupling or isolation can work but you have to find the correct way to do it. Unfortunately the calculations are quite difficult and I suspect even if you did them mass distribution across a tt is not usually very uniform, so most people just try different things until they find something that works.
I cast some silicone blocks and put them under the feet of my Garrard 401 that’s in a slate plinth. They’re soft-ish but not squidgy and they do isolate the tt from vibrations in the unit. Even opening and closing the doors of the unit don’t seem to effect playing at all.

Just ordered 4 of these, my flat is above a busy restaurant and there is an air conditioner unit on the side of my kitchen/living room wall, this emits some serious and I mean serious vibration.

You should report that to your local council’s Environmental Health department and they should investigate and take action since something is clearly not right. Usually the problem with these things is noise impacting on nearby properties, but if the vibration is that bad, then noise is most likely unacceptable too.
I thought about it, but I doubt there's anything the restaurant is doing that is illegal, mind you I did stuff an old shirt inbetween the extractors fluke and my wall, it helped a lot, another thing now is the smell due to overflowing bins, they'll do anything to save money. The thing with the council is that no immediate action can be taken, you have to keep a 'nuisance' diary and that is a chore in itself!

A cheap trick copied from several commercial designs, I have several sets of cones with adjustable\removable spikes. Take three, remove spikes on two and replace with a piece of rubber or cork. Place a trio of cones under kit, two blunt one spike. The spike acts as a ground point a la Goldmund or vertex, and with fine tuning of placement and material can be very efficacious.
I swear by Stillpoints , the old component stands are superb under Kuzma pipebomb ,good value s\h
Ps don’t mix and match diff approaches, Mixing muddles things. Elastomer style isolation to me is thick an slow, spikes just focus the prob. Air is great but can be pricey, I still have seismic sinks I made from shopper bike inner tubes and Mdf, i also like wooden blocks , very big in Japan, along with putting kit on floor.
It is impossible for anything digital to sound analogue, because it isn't analogue!
Listening is the act of aural discrimination and dissemination of sound, and accepting you get it wrong sometimes.
