While I don't have the Salons, I do have the Studios, which are, obviously, very similar. I use the Lamm M2.1 monoblocks, which is a hybrid amplifier with one 6922 tube per side.
I think these amps will give you all that you are looking for. They have lots of bass slam, incredible treble and a touch of that mid-range magic that tubes provide.
Plus, there is no tube rushing, no biasing of tubes and while they are a little hot (not just warm), they are not as hot as those big tube amps you mentioned.
FYI: The VTL 450s are very good amps, with very good bass for a tube amp. (Not quite as good as the Lamms in bass slam, but close. My buddy replaced his 450s with the Lamm M2.2s. Btw, he ran them with the Avalon Eidolons, which is a very similar spec'ed speaker.) If you really want tube amps, I can heartily recommend them.
