What PS Audio phono preamp are you using (GCPH or Stellar)?
Also what digital "sources" are you using?
Unless I missed it (quite possible) I do not know exactly what your "front ends" are.
Anyway, that’s where I would start researching as the rest of the gear (electronics) look pretty good.
As far as the speakers and TT go, perhaps schedule a trip to a good audio show and/or a well stocked showroom that’s accommodating.
