McIntosh MC 901
McINTOSH MC901 est un bloc de puissance mono, mais deux canaux. Ne criez pas au fou (vous pourriez !), je vais vous expliquer. Sur le même châssis de 45 cm de large, le MC901 réunit un ampli à transistors de 600 WRMS et un ampli à lampes de 300 WRMS. Ces deux amplis sont destinés à alimenter la même enceinte, en bi-amplification. Bien entendu, il faut que l'enceinte le permette, comme par exemple les Sonus Faber ou les Bowers & Wilkins, souvent associées aux amplis McIntosh aux Etats-Unis. Il faut donc deux MC901 pour amplifier une paire d'enceintes, soit un budget qui s'approche dangereusement des 50 000 euros. Que voulez-vous, nous sommes chez McIntosh !
