check out Artesania.

these racks are very impressive. do a little research on this rack system. other racks might look a bit more like furniture; Artesania is all business. the Artesania decouples on a level beyond those higher priced racks. if I was not buying a 520 pound turntable, and did not already own active isolation, I would absolutely own Artesania.
I would never consider dropping $20k-$40k on racks that I could never sell. you better want to be buried with an expensive rack because you will own it forever. not that they don’t work, but how long will they be relevant and current tech?
i use footers made in Korea called ’Hardpoint Trinia’. they ’float’ and i’m very impressed by their performance in my system, i have 5 sets of them. they are not cheap, but when compared to expensive racks they become cheap relatively. under my 3 box MSB Select II these footers are phenomenal. they work perfect with my Adona rack or directly on a hard floor.
and using a modestly priced Adona and footers means I can consider changing if better tech comes along and it's all sellable and shippable without losing an arm and a leg.
