The audio industry is in a "circle of confusion." Loudspeakers are evaluated by using recordings...which are made by using microphones, equalization, reverb, and effects...which are evaluated by using loudspeakers...which are evaluated by using recordings...etc., etc. Recordings are then used to evaluate audio products. This is equivalent to doing a measurement with an uncalibrated instrument! Of course, professional audio engineers use professional monitor loudspeakers...which are also evaluated by using recordings...which are made by using microphones, etc...which are evaluated by using professional monitor loudspeakers...which are once again evaluated by using recordings...which are then auditioned through consumer loudspeakers! Thus the circle of confusion continues. It is broken only when the professional monitor loudspeakers and the consumer loudspeakers sound like each other - when they have the same sonic signature, i.e., when they are similarly good. Of course, sounding alike also includes the interface with the room and the listener within it. Then, and only then, can we hope to preserve the art. All else is playing games.
