for me, i move around alot and need to keep the number of physical units to as few as possible. i surmise that any active monitor manufacturer has the opportunity at the spec-design stage and also the actual listening stage to put an amp behind the drivers that they feel performs well. .. and i do not have to deal with the connections, an added plus. i have low-fi, JBL LSR 305's and my main set AirPulse Model 1 (A200 for the rest of the world).. i listen to these all day, every day.
