@lewm you surprised me as with your technical bent thought you would understand the low frequency filter a well sorted spring system ( like the SOTA ) provides… and frankly many on the market today TT isolation bases… HRS to note my favorite.
I am not going to get into the Rega low mass vs rest of TT world debate… i have audiophile / music loving friends quite happy with hot rodding various levels of Rega decks… with … aghast… after market upgrades.. but the RP-10 is an excellent deck… i must admit to giving away a P3/Moth/Signet TK9… hopefully to ?… who will put it on a Rega or Target WALL mount.
re the SOTA… we sold them from day one and had a spare demo table w a Dynavector Ruby that we would loan customers that had footfall issues w lesser ( spring suspension ) TT… Thorens, Linn, B&O, etc…
I don’t remember the SOTA every coming back… and yes it would take a light hammer whack…
re Rick in Colorado… a true analog lover who also sells speakers that are flat in room to 20 hz… so he is VERY aware of environmental isolation….
have fun
if you look in my system photos you will see most of the TT including a 60# Denon w a constrained layer plinth… live on springs..
ymmv always applies
