I am sure it is much more to do with the amps used... and the space you have in the room. And yes 6 moons seems to have praised both pretty equal, but the owner has kept the Gallos for a backup to the Zu definitions he now uses after upgrading from the druid. 2 different sounds for different testing would be my assumption. Also the Druids take nothing to drive, the gallos are pretty low efficiency with I believe 88 db specs ?
