thoughts on phono stage

I am considering upgrading my phono stage, which is currently a Sim 310.  I listen almost exclusively to vinyl (mostly acoustic jazz).  The other components include Hegel H30, PrimaLuna Dialogue Premium, Magico S3 mkI and RP8 (with Apheta cart).  Right now, my possible list includes Sim 610, Sutherland Duo, Pass Labs XP-25 and Lehmann Silver.  My stretch budget might get me up to $6,000 and I will be looking for something used.  Any input will be most appreciated.  My options to audition locally are very limited..............
