Looking for a tube Preamp new or used for under $2000...

Instead of just making an arbitrary decision to get a tube amp, why not just get an amp that sounds like what you want for under $2,000?  Just because an amp uses tubes does not make it good or better than other alternatives.  And keep in mind the cost of care and feeding of a tube amp.  

Another vote for PrimaLuna.  Incredible at the price!

+1 for BAT. I have a BAT VK-600 solid state amp paired with BAT VK-6i tube preamp. I love the combination of the heft of my class A amp with the relative warmth of a tube preamp. You can get pretty close to your $2k budget for an older, but excellent shape BAT preamp with patience. I wouldn’t expect much success overall spending less than $2k though, but I suppose it could be possible with the right circumstances.

Although all the recommendations are good recommendations, the difference as already pointed out is they are different but not better.  The reason why is that the designs are similar and changes are because of the tubes used, the caps and resistors, all low end parts.  IMO buy an old Counterpoint preamp and send it to me.  For under $2K I will build you a point-to-point wired preamp using a better transformer, AC filter choke, better wiring, resistors and capacitors.  All that will be left of the Counterpoint will basically be the chassis.

Happy Listening.
