$20k(ish) tube preamps


I am considering adding a tube preamp. Anyone have experience and sonic descriptions/differences of the Luxman CL-1000, Allnic Master and Shindo Labs Vosne-Romane? Source is digital, and downstream is a Luxman M-900u.  Other similar options to consider are welcome as well.  Thanks!

From my point of view (with my tastes)I would look at anAudio Research Reference 6SE. My system is all ARC Reference components… I have never owned or heard a more pleasing detailed and natural sounding system.

Convergent Audio Technology ( CAT )Black Path, or a used older model like the Renaissance.

No support for the VAC Master? i'm surprised as it's on my short list, tied to my Gryphon Antilleon EVO stereo. Not trying to hijack the thread, but any thoughts on the Master?
