I own a Pass X-3 3 channel I got to round out my home theater rig. I hooked it up to my main speakers to burn it in and was shocked at the speed, tranparencey and overall lack of coloration. I am now replacing my main amp with a pair of Pass X600s. I have not lived with levinson gear but I have listened to a great deal of it and strikes me as being darker and slightly slower than the Pass. If you have great upstream components, the Pass will really let them shine. My Linn CD12 has never sounded so fast.
