Trying to hear "pulsating" from such a refined corner of the audio universe may not be possible when you compare to the brash upstarts here in the colonies (...er, United States).
At last year's Stereophile NYC spring audio show, Naim did provide energized, focused soundstage, along with sounds of real life, through their entry level electronics, and speakers, which might be in your stated budget. This year their website states their amps are "built to swing for another 25 years" so they seem compatible with your taste for action.
The NAIT 5i seems to be their current entry in the same range that impressed me at that show.
