I have a VTL ST-150, and if you find it dark and want something solid state, I'd suggest looking at the Cambridge Audio Azur 840W, which is right in your range - About $2400 new and $1500 used. An excellent solid state amp, with good bass definition and detail. But, it does run hot, so if that's a major consideration, it might not be a good choice for you.
If you generally like the tube "sound" but want solid state convenience you could also consider the conrad johnson MF-2500, which runs cooler and, used, is right in the middle of your price range.
