Preamp help needed - max $ 2500


The sound im looking for " Vocals and instruments have a truer, more natural tonal balance, realistic timbre; the sound projecting into the listening room with increased spatial qualities."

The BAT VK-31SE is a highly regarded tubed that can be found used in your range.
Another option which is tubed but not "tubey"; very neutral and good detail is First Sound Presence DLx Mk2 which should be right in your price range.
I have two preamp which are serving me very well. The Joule Electra LA-100 mk3 and the Dehavilland Ultraverve. Both the preamps are fantastic with good details and excellent dynamics. Both of them fits your budget.
