The McIntosh 275 has been my dream amp for several years. One day this poor audiophile will be able to afford one. Thanks for the great review.

According to MacIntosh, 550 units of the MC275LE will be sold in USA; international sales are unlimited. Hmmmm.... not so limited after all. Even so, I'll be auditioning one with Quad 2905's next week.
