ELAC Debut B6 vs Debut F5 vs Magnepan MMG

Hello All,

I am looking to upgrade my speakers, and have narrowed it down to the ELAC Debut B6, Debut F5, and Magnepan MMG. I've read such fantastic things about the Debut B6 that I am seriously doubting whether the Magnepan MMGs are actually worth over double the price of the Maggies. Could anyone tell me if the MMGs are worth the extra $$, and also what each of these three speakers does best/worst in relation to each other?
