I don't have a favorite speaker system (yet), but I do have a favorite speaker driver. It's the Dynaudio Esotar dome midrange. I think it's a better midrange than the Esotar tweeter is at being a tweeter! I SAY IT REPRODUCES A SIGNAL WITHIN ITS OPERATING RANGE BETTER THAN EVERYTHING, I mean EVERYTHING!!! You name it: ESL's (including the Quads), Manger, MBL, Genesis ribbons, other ribbons/planar magnetics, even ATC's 3 inch dome, and definitely any cone midrange or midwoofer.
