I'll second Jack's observation Bruce.  "Most" of the time, the K3 switches power levels properly ... but, the key lies in Jack's description of how it works.  The K3 gets notice of "events" from the KPA which treats the notices as "fire and forget."  The event causes the K3 to take some action(

Bruce; Did you ever resolve the issue? The KPA500 and KPA1500 send events to the K3, not commands. The distinction is important - an event simply reports a state change in the amplifier. It is up to the K3 to decide what to do in response, if anything. Thus when tapping a and button the KPA sim
