I just purchased some AQ William Tell Zero speaker cables and my jaw hit the floor on the positive impact driving the M3 Sapphires. A match made in heaven and literally transform the sound production from the M3's, now I have to say they are fully better than my Quad speakers, same great midrange, detail is natural also but now with full dynamics and bass to die for. The noise floor is lower, and the imaging is so natural, color and the timber of brass are dead-on, and piano is reproduced if well-recorded like it is in your room, neither pushed forward into the room or back behind the speakers, it is just there in the room. Vocals are also superb just played Ricky Lee Jones, Pop, Pop recording, and it's never as it sounded so good, like you in the studio right in your room, I was always fair on this recording, but no longer it is superb now. The M3's are truth-tellers, they add little and they will give you back what you feed it. So don't skimp.
