Levinson Amps: What do they really sound like?

I have never been interested in Levinson amps, because I was given the opinion they were sterile, clinical, & lacked the palpability of other top SS amps. However, I have seen a number of 'Gon members praise them recently.

What is your opinion of their sound compared to Plinius, Roland, Pass, McCormack, Ayre, etc.?
