I found the Plinius SA 100 mk II/III significantly more detailed, with deeper soundstage, and more air around the instruments. I owned both the BAT and the Plinius at the same time, and compared them often.
The price you pay is somewhat less bass slam with the Plinius (the BAT, in my system, had OUTSTANDING bass extension and slam).
The Plinius might not be your cup of tea, however, unless you're looking for a somewhat brighter amp, though the Plinius is more neutral than bright. I found the BAT to be the warmest solid state amp I've tried, so if you're not looking to go any brighter, you should consider tubes.
The BAT also softened sibilance problems in various recordings, but a the expense of detail.
Note that I was using Pro Ac Response 3.5 speakers with a Meridian digital front end going directly into the amp.
Good luck!
Steve
