A tubed preamp is a great way to put a toe into the water of tube gear. You can find an excellent used tubed preamp on Audiogon in a price range of $1500-$3000.
A few to investigate include: Dehavilland UltraVerve, First Sound Presence Deluxe II, Herron VTSP-1A, and Modwright SWL9.0SE.
Based on my firsthand listening experience, you absolutely will not sacrifice bass response or channel separation with either the First Sound Presence Deluxe II or Modwright SWL9.0SE. User comments on the Herron and Dehavilland have been similar.
