I'm looking for a good tube preamp under I k.

Hello. I'm using a Blue Circle BC21 preamp and really like it. It retails for $1500 new, but can be found for $700 to $950 used. It uses two 6SN7 tubes and is warm yet revealing. Another tube preamp you should definitely consider in the same price range is the Rogue 66, which is about $800-900 used. Good luck!

Hello, I would pick up a used Rogue Magnum 66 pre amp. They are quite rare on Audiogon. If not used you could probably get the regular version for pretty close to 1K from a dealer.

I second the motion on the Blue Circle BC21. For the money (especially used) it is a darned miracle!
