For the money the M200's are very nice, the Paladiums for a lot more money are better, but whomever said used Pass X250 was dead on, for the money of an M200, yeah ok, but for the money of a Paladium get the real McCoy, at that price on my short list would be the Pass, and Edge, Gryphon, and Levinson, (Levinson is in flux as a company, getting service is a long drawn out proposition 6-12 weeks) still the Pass and Levinson are my common favorites, the Edge and Gryphon are also very nice but less frequent used, note: I am not a Krell fan, have a listen and make up your own mind.
