Personal Preamp Evolution


I found the the threads on the amplifier evolution very intriguing,the speaker evolution thread as well .I am not sure if there is already a thread regarding preamps.Many of us failed to mention their preamps[myself included] in the amplifier thread.After all, it really is an amplifier per say.

I keep my gear for a long time. Heard a boatload of new and used preamps when working at the audio store.
Main system:

Quad preamp (#33?)
Audio Reasearch SP9 MkII
Audio Research SP14
Balanced Audio Technology VK30 (my current reference)
Lehmann Black Cube (do phono preamps count?)

Other preamps:

Threshold FET Ten (lasted one afternoon)
Lazurus Cascode (used as a phono stage for a short time)
Classe Thirty (in use in my office system)

I think preamps ought to contain tubes! Do yourself a favour and check out the BAT stuff. Best, Jeff
