Having heard them all--1) Marten, 2) Focal, 3) Magico
The Martens are excellent all around speakers, both the Duo line and the Parker line. I could live with either. Focal has a house sound that is not for everyone. The are noticeably more "alive" in the upper registers and some folks love it while others find it fatiguing. While I like the Magico's as you go up the chain, the A3s were built to a price point and to my ears, are just awful. So many better ways to spend $12K. YMMV.
