Upgrade Advice for music lover


Hi, all!
I've narrowed down my choices based mostly on brand loyalty and sound quality for the money, but am interested in the group's feedback.  Looking for answers to which of my options is best and which update adds the most incremental sound quality as I work towards the end.  I listen mostly to jazz, 80s/90s rock, and newer alternative, often loud :) 

Thank you!

Current System:
Linn Sondek Valhalla (1985, recent Cirkus bearing, orig owner)
NAD 3155 (using pre only, recently serviced)
NAD 2200 
Polk Audio RTi8

Anticipated System:
Linn Sondek (TT above, and an upgrade to Lingo 4 $2k)
NAD 165bee or NAD C658
NAD C298 or NAD 275bee
Monitor Audio Silver 8 (used $650) or Paradigm 800F (new $2k)
