Powered speakers show audiophiles are confused

@lonemountain In production sound 90% of all our energy is to accurately record the actors dialog, we would like to use a boom mic like the Sennheiser MKH-50 all the time but when the stupid directors (yes I'm still bitter) shoot wide and tight shots at the same time we can't get a boom mic in and we have to rely on hidden mics or lav mics hidden inside the actors clothing. The boom operator memorizes all the lines and points the mic at each actor as close as possible to the camera frame line without entering into the shot or throwing a shadow on anything in the frame. The mixer blends all the microphones booms and lavs raising each mic when the actor speaks, it's a lot like playing an instrument that is the actors, we try to minimize background and any noise that would interfere with the dialog. 

I called on Coffee Sound in Hollywood for years and it was indeed a whole different world of gear.  

@lonemountain What do you think about the Steinway Lyngdorf Model B  system. They have the same speaker philosophy as we do I think. There are some good short videos on their page. 

Can't quite imagine a Nelson Pass class A amplifier in a speaker cabinet.  So you have a few feet of speaker cable for an outboard amp.  I don't see it as much of a problem.
