If you replace the 3.7 Mye stands with Sound Anchor stands for the Maggies, they will come alive.
I've heard several sets of different Maggies (old and new) with the Mye stands and they sound dull and lifeless compared to the way they sound with the Sound Anchors. The Mye stand effect is almost like the non-resonate, slightly dull sound of an overdamped room.
I think it's because the way the MYE stands clamp to the speakers thus eliminating some of the ultra fine vibrations that seem to add air and life to Maggies.
It seems that Maggies aren't supposed to be rigidly mounted, or Jim Whiney would have built them that way from the start...they need to be free to resonate like a violin.
Sound Anchors add a rock solid base for structure and a little height to get them off the floor, but allow the speakers to resonate naturally.
