Where to spend my money...

Over the years I've mostly purchased great used gear that works within my budget....and with much success.

I'd like some input on where to next invest my money for the most sonic improvement...a new turntable and stylus upgrade vs a new power amp.

I'm interested in pre-owned VPI tables and Pass Labs amps....particularly VPI Primes over the last say ten years....and something close to the current  Pass Labs X-150.8.

I currently enjoy Wilson Sophia speakers (version one)...a VPI Scout Junior TT with a Dynavector cartridge....Audio Research solid state 100.1 power amp and LS-16 Pre-amp.

I listened mostly to vinyl  (jazz and classical)...but also have the Cambridge CXN V2 streamer with Qobux as my source.  I realize any Pass Labs amp will stretch my budget but I'd like to get some input. I could see spending $2200.-$2700 on a new TT...and for the amp maybe $4000.00 to $5000.00 eventually...Just can't do both at the same time...

Any thoughts are appreciated.
