OK, so I received one of these things on Monday. I plugged it in the main system briefly today. The speakers are Carolina JTM, Konus Essence replicas. Usually, it is powered by a Gaincard. Without going into differences in sound quality yet, how come the Jordan drivers verberate intensely with the Sharp, but it hardly moves with the Gaincard? I don't have an SPL meter, but I am pretty sure they were playing at about the same volume. It is because I drove the Sharp too hard?
