Of the tables you list I like the Feickert Blackbird but if it was my money I'd be getting the Kuzma Stabi R with 2 "wings".
SME Model 15 MK2 vs Feickert Blackbird or Firebird or Sota Millennia Eclipse
Considering possible turntable upgrades. I have an SME IV.VI arm from about 10-15 years ago and an older Sota Star Sapphire table with vacuum hold down.
Option 1 - SME Modem 15 MK 2 with new motor
Option 2 - Feickert Blackbird or Firebird
Option 3 - Upgrade my Sota to a new Millennia Eclipse
Thank you!
