ASR Emitter II or Burmester 911?

Hi,I own and enjoy an ASR Emitter 1 Exclusive driven by a dCS Paganini set up, into B&W801ds. The sound is quite beautiful - voices and instruments are very natural, colourful and quite expansive. Recently I tried my old UCD400 switching amps for a change. The sound was etched/detailed, less vivid, less natural, but punchier, with much more controlled and extended bass. It was quite a lot of fun - it had more boogie factor I guess. So now I wonder how I might get the bass of the UCDs with the beauty of the Emitter 1. Maybe Emitter 11's? I suspect the 11s will have quite similar (family) bass to the 1s though. Or maybe the Burmester 911? I'm not in a position to try either before buying so would appreciate any experience here. TIA!
