hi Giglr,
i just noticed you use a tall Salamander rack. you might consider doing an isolation shelf of some sort under the turntable as your rack is likely causing at least some blurring of the sound. it should be easy to experiment putting various materials under the turntable and see how different things change the sound.
also, related to the same issue; what are you using for a platter mat?
bad set-up on the plinth suspension could be most of your problem but the rack and platter mat could also be contributing.
good luck; an LP12 is an oldie but a goodie.
