My experience is primarily with the amps (and speakers) that I sell, and I don't sell Levinson gear. I can't say that I've heard Levinson amps in a familiar enough environment to make a fair and reliable assessment, but my impression has been that a Levinson amp of comparable power has a bit richer presentation, while the big Parasounds are a bit more lively and maybe a wee bit more articulate. I would say the Levinsons sound more like you're towards the middle or back third of the hall, while the Parasounds are more like the front third of the hall (I'm not talking about depth of image, but about overall "feel"). I can easily seem some speakers or listeners prefering one amp, and some the other. I have reasonable familiarity with several solid state amplifiers that are roughly two and a half times the price of the Parasound, and I think the Parasound is at home amongst them. Again, it's hard to speculate which amp might be the better choice without knowing either the speakers or ears involved.
