Now I have never used your Microseiki turntables but I find it interesting that their chief designer now makes only belt drive turntables. (Techdas)
A thin platter and a rubber mat are not much for shielding. The best shield from magnetism is distance.

I have mentioned only Micro Seiki BELT DRIVE, not any Direct Drive from them. The Belt Drive from Micro Seiki is something like this. Do you know the price? Not sure how many reference direct drive turntable anyone could buy instead of one Micro Seiki reference belt drive, the price is insane!
Chakster, in order for any turntable to be first class it has to be able to maintain speed in spite of any reasonable interference, it has to have an adequate record clamping system either reflex or vacuum, it has to be able to mount any tonearm you desire and it has to have a suspension that isolates it from anything over 2 hertz both vertically and horizontally.
No direct drive turntable I know of meets all of these requirements.
I am able to mount almost any tonearm on my $4000 Luxman PD-444 direct drive. Not a fan of vacuum clamping, but disc stabilizers or record camp like Micro Seiki ST-20 / CU-180 mat is what I use. Long time ago we came to conclusion here on audiogon that Luxman motor was made by Victor (not Micro Seiki). This turntable is suspended. Mode images here. The armboard system on the rails is the best I have ever used, ideal for tonearm collector like myself.
More reference direct drive turntable that you may never tried:
Victor TT-101, Denon DP-80, Technics Sp-10 mkIII or latest SP-10R.
All those are the best bang for the bucks as Lewm pointed out.
If a $2000 drive can give you more than $20 000 drive then why even look for the most expensive? You’re talking about turntables what will never be withing a price range that I (and many others) can spend on a turntable, in my opinion it’s a waste of money.
