Your setup is pretty good at the moment. You might want to upgrade other bits eg phono stage or arm to Schroeder Reference (much better than SME V). However, a SY is going to set you back at least 4k GBP. That buys you 200 new audiophile records or even more second hand.
I have a Platine Verdier, Schroeder Model 2 and Allaerts MC1B. Ok I could improve things eg battery PSU, better Allaerts cart etc. But at then end of the day, I listen to the music with a bottle of wine - so I just buy more LPs (or even some wine - how about 10 cases of 2003 Chateau Leoville Barton en primeur!).
