I wouldn't consider any of those Levinson amps if I were you. Your Pass X-250 probably sounds much more natural. Levinson can sound thin or clinical without the proper surrounding gear. Many Levinson owners are also having service issues since Madrigal sold out to Harmon International. If I were you, and looking for more detail than your cuurent Pass X-250, I'd look at an older Krell, for service reasons. If you're looking for more musicality, and want to stay with SS, I'd recommend Jeff Rowland amps. Otherwise, try a tube amp. I know Levinson gear is going at a good discount here on the 'GoN, but there is a good reason for that.

PS. If you do buy a Levinson amp, I'd definitely get a tube preamp to warm up the sound.
