I think there are many offerings, a lot of the solid state designs will have tube like character. There of course the old standbys Mark Levison, Pass Labs and higher end Krells. The KAV series just do not sound like a Krell to me. Another Brand I really liked if you can find it was Chord. Very silky and rich but also very expensive and not readily available in the US.
More Modestly priced offering I liked was BAT, Electoacompaniet, and the venerable McIntosh.
However the McIntosh amps I listened to are very neutral and may not have enough warmth for you. However they are not sterile and etched either. In my auditions I found that the BAT came the closest to sounding like a tube amp. Even so they are more laid back in the midrange and did not sound exactly like the tube gear I own.
