When you say what league or what Pass compares to are you talking competition or what does Pass sound like? In my opinion build and quality Pass is in with Levinson, Krell, Classe etc. When I say that, each will have their sound but all are high quality and over built. Sound wise I really can't say Pass sounds close to anything else I've heard. Having owned Krell and CJ, Pass is some where between them with bringing the best of both to the table, solid state control and transparency similar to Krell but to it's attribute IMO not as iron grip and warmer, wonderful midrange and musicality like the CJ, but again not to the CJ extent. If the associated gear can deliver it Pass is capable of revealing wonderful textures of the sound.

Blackraven, the Maggies must draw more current, my X 250 gets warm but not to the extent you mention, I don't think I've ever felt the front get warm. Granted though, if you don't want extra heat in the room you might want to reconsider. To my knowledge Pass does not have a switch, the amp is designed to run Class A to a point and then A/B. I know the X250 doesn't. Heat or not, I'd love to be able to afford a set of Passes Class A monoblocks.
