Yes, the reason why I'm going with the Active CLR rather than the passive is the active is designed to work with that specific monitor. It will therefore give you the optimum quality. I can simply turn off the Kemper power amp and run this way and hear the profiled cabs in all their glory without being compromised by coloration from my own guitar cab. The passive monitor may very well sound great too but can never surpass the active. It is for this reason that I am anxious to hear a shootout between the active and passive CLRs hooked up to a Kemper. Just how significant IS this difference between the two. I don't know.
But owning the Kemper Power Head also gives me the option of switching the cab profile off and playing my favorite amps, the Marshall Silver Jubilee and the Marshall Super Lead Plexi live, directly thru a 1960A Marshall 4x12 cab loaded with my favorite speakers. Best of both worlds really.
