Here's a great quote from Bruno Putzeys on ProAudio forum .... One possible reason why speakers are relatively neglected in audiophilia is because of an odd competence cascade that has crystallised in this particular segment of the industry. We all know that making something good in any product category requires a lot of knowledge and experience, but this is often not how it works out in consumer high-end audio: Those capable of making good converters and solid state electronics, do. Those not capable of making good sounding solid state power amps, make tube amplifiers. Those not capable of making tube amplifiers, make loudspeakers. Those not capable of making loudspeakers, make cables. Those not capable of making cables, sell rocks said to dramatically improve sound.
