I'm not advocating that people absolutely disregard specifications or measurements either. I just feel that what makes loudspeakers or electronics sound 'musical' or otherwise is far more complex than that which can readily be quantified. I've listened to many loudspeakers with apparently excellent technical specification which render music (for me) into a relentless dirge. Ditto amplifiers. The only area where I've experienced some correlation is in the field of digital electronics and particularly cd players which can sound 'noisy' and uninvolving as a result. The artefacts in their measured performance can sometimes account for this perceived untidiness. I don't believe the measurement techniques required to analyse analogue electronics or loudspeakers satisfactorily actually exist yet.
