I'm giving the a1400-8 a good listening over several weeks. It really impressed me recently with an old track by jazz/classical trumpet player Wynton Marsalis "Napoli, Variations on a Neapolitan Song" from Carnival. Its a trumpet accompanying a wind ensemble so its full of quiet passages and searing high pitched trumpet solos. You want dynamic range, well that one has it so its a real test for how well the amp can start and stop and respond to fast demands for power. I've heard that tune many times and the natural crispness of the cymbals, brass and trumpet with the Axiom amp really surprised me. \:o
