Top Ten Tube PreAmp of all time?

This thread for you tubeguys.Nominate your favorite tube Pre Amp of all time. More info for audiogon members the better. Remember some members are just starting their high end experience.
I have to go along with the SP10 MKII but my new favorite is the Atma-Sphere MP-1 MKII.
VTL TL 5.5 soooooo sweeeeeet. Full body and great soundstage. A must see before buying anything else. It blows away pre amps twice the price.
Audible Illusions 3A or if you prefer less warmth the L1. A friend has a Marantz 7C that he claims is tops. It has had the usual maintenance plus a rebuilt (rewound) power transformer and also the addition of a custom designed volume pot that maintains the soundstage and detail as the volume drops. My personal favorite is the L1. I withdraw the Pas3x in favor of these.
