How have you been able to achieve excellent detail retrieval without getting an etched fatigue inducing sound.
I found the solution was to go to pro studio speakers. Consumers designs are all designed to impress the listener in one extreme way or another - they are mostly looking for that "differentiating" factor to sizzle up the sound and stand out from the crowd or give good reason to buy this years model over last years model (different sound).
Audio engineers listen to music nearly all day, 8 hours a day five days per week. Audio engineers require detail and transparency in order to make precise adjustments. Audio engineers are often deeply familiar with the sounds of real instruments and musicality. Audio engineers want their productions to translate to other systems and therefore seek accuracy with the lowest amount of coloration possible from monitor systems. It is a "no brainer" that the most popular speakers used in pro audio mix and mastering studios are all of what you describe; musical, transparent, detailed and without being at all fatiguing to the ears. This not to say that studio speakers don't differ in sound from eachother - they do, however, consumer speakers are much more of an eclectic, eccentric, anachronistic mixed bag, as they cater to a such a broad market where being different is often more important than achieveing accuracy.
Are pro studio speakers right for everyone; probably not ....because they lack coloration or sizzle and certainly won't improve a bad recording, worse they will reveal a bad recording all to obviously.
