Yeah, I dig 'em too. 
 
Though I don't know if I'd want to warm them up -- not to say that they're already warm, they aren't, I'd just want to complement their strengths which are frequency extension and detail (modded X-CanV2 did the trick alright).  But if that's what you want, then go for it.  Haven't listened to them out of any of my tube amps recently, will give them a try later.
