$1600. preamp

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.  

The Audio Research SP-14 is a nice pre-amp. It has a good tube phono stage in case you want to come over to the dark side sometime, and can be had for $1000-1200. 

No question about this recommendation, check out Don Sachs’ tube preamp. The preamp is custom-made, based on 6SN7 tubes and is the most satisfying amp I have ever had in my system, which include Modwright, Belles, Berning, and a upgraded HK-CI. It is detailed, transparent and has incredible extension on both the low and high end and a luscious mid-range. Google "Don Sachs" and you can learn more about his wonderful preamp, which is right in your price range. Support the boutique manufacturers, is my recommendation. Whitestix
