Fun reading. Back in the 1980s I was a grad student working in a leading hearing research lab (we published in Nature and JASA and similar journals) doing my own MA research and building systems for other researchers. This gave me a good excuse to spend time in high end audio stores listening to equipment and measuring things with our labs gear. I learned several things during that time, including: 1. Most high end audio gear is purchased by middle aged men with presbycousis and little hearing above 12K. 2. Thanks to temporary threshold shift, your hearing sensitivty changes rapidly over a listening session, even at moderate levels. This plays havoc with auditioning gear. 3. Much of what is described as ıairı or ıpresences is harmonic distortion. 4. Audiophile gear companies have stubbornly hung on to high impedance interconnects, while pro audio only uses low impedance interconnects because with low impedance, audible cable differences disappear. 5. A good $500 CD play...
