Top Ten Tube PreAmp of all time?

My favorites are custom-built linestages made by Aldo D'Urso, an Italian builder/designer.  He uses mostly vintage parts, including Western Electric capacitors and transformers.  I have one of his custom linestages that employs output transformers and uses Western Electric 310 and 348 tubes.  The one concession to modernity is that he put in a motorized and remotely controlled volume pot to accommodate my laziness.  

I have heard other models that he made that are extremely expensive and nice sounding.  One has a pair of output transformers that, the transformers alone, cost about $20,000 a pair if you can find them.  

Of slightly more commercial availability, I have heard and liked both the Audio Note (uk) M-10 and M-8 linestages and I also liked the Kondo M-10.  Shindo also makes some good linestages.  At a much lower price point, the top-of-the-line Atmasphere linestages sound good too.  

Around 20 years ago, I went to my dealer to audition the Stax 007 Omega II headphones.  They sounded great, so I ordered a pair along with the Stax tube amplifier/energizer.  When I got it into my system, it did not sound nearly as good as what I heard in the dealer's setup.  When I asked about that, the dealer informed me that I auditioned the headphones while they were being fed by a Kondo M-10 linestage, which, of course, sounded much better than anything I had (or could hope to have). that is why it makes my list.

Although I am primarily a tube-electronics person, I would not turn down a Lyra Connoisseur phono stage.  I heard the most explosively dynamic and vibrant analogue playback in a system having that solid state phono stage.
