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.
