Preamps: Rogue v. VTL v. Blue Circle

OK, I am a bit of all over the map in terms of price, but I am looking for best value, not necessarily within a specific budget. WOuld like to be under $2K though. Buying used.
My candidates are:
Rogue 66 and 99 Magnums
VTL 2.5 and 5.5 (someone told me the VTLs have reliability issues. True?)
Blue Circle 21.1

No phono required. Where would you cast your votes in terms of value? I like a transparent enough, but not too revealing preamp, slight tubey character but not too much, and large soundstage depth and width. Good extension on both ends also a factor.
Help?
