I'm speccing a system for a new house and I've had issues in the past with the Hybrid CL keypads causing SORAA LEDs to buzz when dimmed. Does the new "PRO" Maestro do any better? I noticed that the "PRO" Maestro has RTISS, whereas the CL hybrid keypads don't, but I am not sure if this would impact dimming performance or just keep the light steady when voltage fluctuates. I'm trying to figure out if I should spec the "PRO" maestros to control LED loads instead of the hybrid CLs. Any insight into how these two products perform with LEDs would be helpful.
