VTL ST-150 vs... ?

Hi all, I'm currently evaluating amps and so far the one I am "settling" on is the VTL ST-150. It has a big expressive sound with great, rich texture and natural timbre, but everything has faults and for me the VTL could use some more focused imaging and is a bit dark sounding. Plus, I would prefer solid state to avoid the heat and maintenance of tubes (class AB over class A would be great).

So, people who have owned or have experience with this amp, what have you moved onto or chosen over it in a similar price range ($1.5k - $2.5k used) and why?
