I listened again to the Personas today - 3F. (Bryston amplification)
Also the B&W 803D3.
I found myself underwhelmed. The B&Ws sounded more refined (even if they too have a sculpted frequency response), the Persona's sounded somewhat opaque to me, and even though the B&W's upper frequencies actually sounded a bit hotter, I actually found myself getting fatigued faster with the Personas high end. I found the same when I did a longer audition last year. I guess I just don't care for those speakers. And they sure didn't sound a competitive as I'd hoped with even the B&Ws. (And I'm not even much of a fan of the B&W sound at all!).
