The Klipsh speaker brand makes some crisp sounding models. They have horns for tweeters which can be more forward sounding that way. Speakers have the largest influence on the sound by far, but generally speaking tube amps would be warmer and perhaps not to your liking. Another speaker brand would be Paradigm.
Narcisco that's the thing. It's hard to know what you consider live or crisp vs just plain irritating. It sounds lke you may be newer to the hobby, in which case you would be more than happy with Emotiva electronics. They make good entry level stuff that doesn't cost as much, good bang for buck there. You would be happy with their speakers as well, come to think of it. Maybe phone them directly, they can steer you right.
