Turntable Advice?


My SOTA Star Sapphire motor has gone bonkers, so I'm planning its replacement.  Hoping to get some thoughts on my options - I think some of you enjoy a challenge like this.  Major components are Aerial 10T's, Classe 6 Mk II pre-amp, Classe DR-150 amp.  Primary listening is well-recorded jazz, blues and solo guitar.

I could either re-use or sell my SME V arm.  I'm hoping I won't have to shell out more than another $1,500 either way.  Here's what I'm thinking:

1)  Get a new table and cart for the SME, have it all set up by a local pro
2)  Buy an old SOTA and cannibalize the motor
3)  Sell the SME V and go with:
  • New Music Hall mmf-9.3 with Goldring Eroica LX (no head amp needed - Classe has a MC input)
  • New Music Hall mmf-9.3 with upgraded cartridge (suggestions?)
  • Rega RP6 with Exact 2 cartridge
  • Clearaudio Concept or Emotion w/ dedicated arm and cartridge
  • Used table/arm (as long as it's durable)
This is admittedly a very wide-ranging list of options, but I'm all ears.  What would you do?  Thanks in advance!

The motor is NOT AC.  The terminology 3 phase DC means that it is a brushless DC motor where the windings are excited by a switching DC power supply which turns the power on & off to the correct winding at a very fast pace such that the fixed magnet in the motor tries to "keep up" with it, hence the rotation:

These motors last a long time coz there is no grinding brush to wear off but the driving electronics has to be spot on and are very complicated.
