Preamp under $2,000.

On US Audio Mart there’s a Don Sachs pre for $2k and a Linear Tube Audio MZ2 (with upgraded power supply) for $1300.  Both great, but if you can stretch for it the Sachs pre is an end-game level component.  Best of luck. 

soix asked a very important question. Without knowing the preferences of the OP we might as well print out a list of every Preamp that can be purchased in that price range.
Me? I wanted a warm slightly tube sound so I picked up a pristine Audio Research SP-8 ver 5 and have been delighted with it.

I want something that matches well with my Primaluna Dialogue 7 tube monoblocks. They are kind of warm. The Tannoy Revolution xt8f speakers are kind of bright. They go good with the Primalunas. I am pretty sure I want to stick with tubes for the preamp. This is for my second "living room" Sunday morning kind of system. My system in my man room upstairs is killer. Adcom GFE-585se with Dunlavy SC-V speakers. Streaming upstairs, turntable downstairs.

Rogue RP-5 with new tubes on USAaudiomart for $2k.  I think those have a nice phono stage

I have a Musical Fidelity M6 phono stage. My turntable is a Marantz tt-15s1 with a Sumiko Blackbird mc cartridge. I really like the phono setup I have.
