As a fan of tube preamps, Klyne is the only SS preamp that I would consider.
I certainly haven't heard them all, but I've owned Levinson, Krell, Classe, Rowland, Klyne, Coda, Threshold and had Ayre, Pass Labs, Spectral, and BAT preamps in my system.
I have not heard Vitus, Burmester, MBL, etc., but they may be over your $10K range, even used.
Curiously, how hard is it to change tubes? Some tube designs even have the tubes openly accessible.
