Best turntable and arm under 10k?

The one table that I find extremely interesting and heard only once is the Bauer DPS series. An unforced and beautiful presentation. It is one that left a lasting impression on me. Not sure of their availability.

My Sapphire also back at SOTA
upgrade and put a better arm on it

Bardo should be on your list also IMO

I had my Sapphire repaired & updated @ SOTA a few years ago with new suspension, platter, bearing and power supply.  That gave it the stability to really take advantage of a major arm upgrade.  I ended up with a Graham Phantom and it really rocked my world with the DV cartridge I selected.  I'd also suggest you take a hard look at the Tri Planar and Reed offerings.  I've read some really glowing reviews of their arms on SOTA tables.  SME makes great arms, but I believe the others potentially offer better synergy.  Good luck & happy listening!

SME Model 10A. SME makes the best turntables and tonearm s in the world.

Without bringing up turntables you didn't mention, I'd go for the Kuzma Ref, among the ones you named.
