Tube Preamps...I'm sold

At the constant urging of my friend I finally decided to audition a tube preamp (Eistein The Tube). All I can say is I am completely sold on the benefits of tubes in my system. I am not sure I have the vocabulary to describe what I heard but everything just sounded right. Vocals has a realism that made it seem I was in the same room as the musician. Instruments sounded like they were supposed to. There were details I have never heard before. What is amazing to me is that I have what I believe to be a pretty good ss preamp (Classe CP-700).

Ok, now for the hard part...finding the right tube preamp. The Einstein is amazing but I want to audition more. Can anyone suggest a tube pre in the range of $10K and less? I would love to some one with an output trigger and very fine volume control (0.5db). Thats all I need.

Thanks in advance.
