Preamp Choice: Rogue 99 Magnum vs. BAT VK30

I have both of these preamps, and they both have their plusses and minusses. Both have remotes, which I like! The BAT is chock full of features, the Rogue fewer. I have yet to get away from Stock tubes, and so I don't know how their sound will change when I get some better NOS tubes in them. Has anyone heard the two of them with good tubes? Which is more transparent? Any report of sonic qualities, or good comparisons, would be very appreciated!

OH - and the rest of my system is a Bruce Moore dual 70 tube amp running KT88's, Proac 2.5 speakers, an Arcam CD23 CDP, and a Linn LP12 TT with Denon DL103r cartridge. Thanks.
