Upgrade from VPI Scoutmaster

My Scoutmaster is now 21 years old, it is in great condition but I wonder if I could improve my analog experience.  I was pretty happy with the sound earlier but in the last year I changed the cartridge from the Koetsu Black to the Rosewood signature platinum and then upgraded the phono stage from the Sutherland Duo to the Dos Locos and each stage revealed a new level of musical content from the LPs so I am wondering if there is anything to be gained from a new arm and table.

(As an aside, if you have a low output, low resistance cartridge and the budget, AUDITION THE DOS LOCOS.  The most hyped up reviews scarcely do it justice IMHO.

My budget would be $10K +/- $2K.  I have contemplated the VPI Dragon and the Signature 21 'tables.  I have no idea which would be better and in each case I'd need to add a headshell weight because of the low compliance of my beloved Koetsu RSP.

Does anyone have suggestions regarding which, if either, VPI is a better match or if there is a different table & arm combo, in that price range, you would prefer.

The rest of my system is an LA4 pre, various amps  - SE 300B or 2A3 Elekit TU-8900, a Pass Labs XA25 or my own home brew PP 6SN7 - 300B Balanced, Rockport Atria II speakers - held together with Cardas Clear Reflection.   I listen exclusively to "classical" music, anywhere between the 11th and early 20th centuries.

I'd truly appreciate thoughts on how to get the best out of the cartridge.
