PMC MB2 vs Revel Salon 2 vs Dynaudio Sapphires

These are all great speakers. I'd suggest you give more details to help people give suggestions - for example have you heard each of these speakers and what were your initial thoughts? What is most important to you bass or midrange? etc.

Thanks guys. I look for the one with sweet and clear high, accurate mid and heavy, punchy, clear and detailed bass with authority. I think i will go to audit them soon...

IMHO, Heavy and Punchy bass are kind of an oxymoron. Generally heavy bass tend to sound boomy or muddy whilst the tightest punchiest type speakers actually sound rather bass light compared to the usual fare - that is until you crank it in which case the punchy bass sounds much more powerful and in your stomach than the heavy or plodding room vibrating "heavy" bass.

I realize this all depends on how you define heavy...

FWIW - neither PMC nor ATC are "heavy" in the bass compared to most speakers but relatively speaking PMC will "heavier" whilst ATC will be "punchier" (in my sense of the word - if you grasp my meaning)

Good luck - I hope this clarification helps you in your search.
