I briefly used my PL 6 monos with Cremonas. The Cremona does need some grunt (I'd call it a "modestly difficult" speaker to drive), but that particular PL model was a very good match. The Cremonas ended up in my living room with a smaller, more "style consistent" mate (Pathos Classic One/Digit) for WAF reasons, but I'd be happy with the sound either way.
