Top Ten Tube PreAmp of all time?

I would think that the CAT SL-1 (any model) would have to be in just about anyone's top ten. The CAT just eclipses everything else I have heard, especially if you do your own tube rolling to match the rest of your system. Yes Avguygeorge, I will stand up and be counted. Bass extension, midrange presence, soundstage, dynamics, transparency, smoothness. I just don't see how it can get much better than this. But, my mind is still open and while I haven't heard everything mentioned in this thread, IMO, some of the suggestions just don't compare. I understand listening evaluations are subjective, so don't get mad at me guys.

I agree the CJ PV-9a is the best non Premier preamp they ever made. Phono stage is incredible. The ART is the top of the list.

AIR TIGHT ATC-2

Audio Research Reference one, replaced my SP11 Mk II which I loved for years

Jadis JP80mc, my favorite for years. A classical lover's heaven! Also the Aesthetix IO (haven't listened to the matching line stage, but if it's anywhere near as good, it should be included). The ARC SP-10 Mk II is also a classic. In the less expensive stuff, the Audible Illusions 3A. Everything else mentioned is also worthy-there's no shortage of fine tube preamps.
