Best sturdy floor rack for turntable

Hi guys

i own a Brinkmann Balance tt that until recently was mounted on a wall shelf and sat on a granite slab (the granite slab being recommended by Brinkmann).

For (sad) aesthetic reasons I’ve had to lose the wall bracket and the tt will have to slum it on a floor rack.

Is there anything out there that gives good isolation from the floor (wooden floorboards under carpet) ?

I can sort out the mechanical vibrations with a variety of options such as HRS etc but the main problem I foresee is getting something that isn’t intrinsically wobbly....

Needs to be readily available in UK so esoteric stuff in the US unlikely to be much use !

cheers 👍
