Three plus years ago I was "on a mission" to find a new pair of floor-standing speakers.
One of my stops was at a dealer to audition the then Magico S5's. As the "main" listening room was occupied, the salesman hooked the speakers to a Hegel power amp with a very high damping factor. When the "main" listening room became available, he wheeled the S5's over there and connected it to a pair of large tube monoblocks, with a very low damping factor, and driven by tubes, the Magico's sounded much more "musical" and had more bass. I suspect that, the pairing of a low damping factor and the Magico bass driver just worked better together.
