There are separate threads on this but the TLDR summary is - it depends but it can be worth trying a few things yourself instead of believing consensus.
I spent some time a couple of years ago trying to improve isolation on my Cherry LP12 (Kore and Ekos).
It’s on a Target wall shelf so I assumed for 20+ years that a Tramp was unnecessary or worse than no base - experiment at various times in various places supported that.
I assumed that swapping the MDF board on the shelf for laminated glass or a slab of granite would be horrible (if changing nothing else). That prejudice too was supported by testing.
I assumed rubbery feet (I tried HRS because of free trial but other options exist) would be worse than not having them. If above a chink of granite and below the MDF on which the LP12 feet sat, that turned out to be wrong- with care, we got fractionally less sibilance and better stereo and no big minuses, contrary to ‘conventional wisdom’. Even if the layers looked a bit silly, they combo stayed.
We also tried the SRM base and platform instead of no base - a modest difference but another improvement.
Then I got the chance to try a Stiletto/ Skorpion/Keel. It gives the same boogie as the old LP12 but is a little better for air/ speed/ air/ neutrality/ clarity in all the areas we noticed.
We did try rubbery feet, different platforms and so on under the Stiletto but 4 listeners could all hear
Literally no improvement over Stiletto directly on the MDF board that the Target shelf came with in about 1988.
So the Stiletto stayed but the rubber feet and all the other bits of faff didn’t.
