Best tonearm under $2k

I’m looking to upgrade the tonearm on my Acoustic Solid Bubinga wood TT. It came with a Rega Rb330 tonearm and although it does a pretty good job, id like to squeeze out a bit more. I just replaced the Denon 103r cart with a Soundsmith Zephyr MIMC Star cart and I don’t think I’m realizing it’s potential. I also upgraded my phono to an EAT E-glo S which I think would also benefit from an upgraded arm. My power amp is an Audion 300b Silver Night Special Edition driving Zu Soul Superfly’s. 
I’ve got one dealer steering me towards the Jelco 850s and another dealer suggesting the Sorane SA 1.2 tonearm. 
Does anyone have any listening recommendations on either of these?

Thanks,

Rick
