I'd be careful. I heard some B & W Nautilus 800's powered by a Mark Levinson 333.5. The sound was way too bright for my tastes. I ended up with McIntosh amplification. In your posting you're talking about different model of speakers and a different model of Mark Levinson; so maybe they work okay. But from my previous experience, I'd be inclined to be careful. Make sure you audition before buying.
