Upgrading Turntable suggestions

I have a Project RM 10.1 Evolution with a 50 hour old Soundsmith Zephyr mkii cartridge for sale for less than half your budget. Terra cones underneath, speed box speed controller, isolation base. All together, retail is $5,100. Didn’t get a chance to list it here but it’s on the other site. I set it up with the Fiekert tool and set azimuth with a fozgometer. It’s ready to play.
PM me. It’s a killer combo.

Feeling the need to tinker and possibly get more detail and soundstage from my records.  

Oh no, I am not sending my turntable to California for Brian to dial it in, and he doesn't sell Nottingham.

The Rega RP10 with Apheta cartridge is supposed to be superb and squeezes into your budget

You will be disappointed with just replacing your turntable.  Sure there will be some  improvement in speed stability, etc., but I'd look elsewhere for improvement that is worthwhile.
