I've got the small MBL mono blocks, 8011AM. Don't let the size fool you, these boys are really powerful. I think these amps are a hidden gem. They've outperformed everything I've heard including some very expensive amps (darTZeel for example), and some hyped ones (ASR Emitter II Exclusive). They work great in other setups as well, an all-MBL setup like mine is certainly not required. For example, another guy in this town bought them for his Wilson WP7 and he claims they are stunning in his setup.
Anyway, if you can, lend them an ear and see what you think. :) They're breaking your budget a bit unfortunately, but if you can find them used they should be right on the money.
