Good morning, maybe someone can help me out? I have a 3 way set up. Klipsch LaScala's ll base bins, 511b with GP 902 & a Faital Pro tweeter. Running thru a ALK ES500 & es 5800 cross over. I just purchased a set of 311-60s & the step down adapter from 1 to 1 1/4. I cant seem to get the sparkle out of the 311s I had with the 511s. Tried tube rolling my pre amp( Don Sachs), changed the terminals on the actuator. Can it be the driver is the issue? Dan
