At this price range, you should put the Audible Illusions Modulus 3A on your audition list. Galen Carol Audio sometimes has factory refurbished units at a nice price.
I owned a Modulus 3A and think it be a great pre at the price for a vinyl based system. Would look for a used Audible Illusions LS1 for digital. Currently using a Jolida Fusion pre ($1350 new) and enjoy it.
Atma Sphere UV-1.   In that price range, you can get one with a phono stage.  It blew away my Quicksilver pre, though I use it with Quickie silver monos.
