Levinson is NOT tube-like!!!! I have heard ML amps called a lot of flattering things but never that before... I like ML gear but just would never call their amps tube-like.
I honestly beleive that there is no such thing exactly as tube-like SS. I know that isn't helpful, because I've asked this same question before. My listening gave me the following close calls (in descending order): Boulder, Classe Omega >> Sim, Ayre, Marsh, and I guess tube hybrids. The Boulders sound like very expensive tube amps (they all seem to meet up on the very, very expensive side since LAMM doesn't sound very tubey either) - not "tubey" but musically enjoyable and somehow "right" for SS.
I have a more basic question, though: Why not do a VTL MB 450 or another high power tube amp. If you want high power amps that sound like tubes, why wouldn't you consider high power tube amps? What are you driving, incidentally? (this is the only place where I can ask this and not get "M3" or some other car as an answer!)
Just my $.02
