My boss's wife have a similiar "six" sense when it comes to car. His understanding is that unlike men, women listen or choose a product without a lot of technological bias. Some time it's just better and quicker that what. Cheers!
Amps and Women
I have been happily married for over 20 years now. I am the supposed audiophile, yet my wife ,god bless her, can pick out the differences in amplifiers in about two seconds. I change over from my Spectral stuff to my Classe stuff,"Honey did you change the system again?" She was not even listening seriously, she was doing something totally different. So the question I pose, and my wife is not the only one I have noticed this with, do women in general possess better listening/hearing capabilties then men?? That is why I take her(and usually with great resentment on her part.) to audition audio equipment. In fact, in all fairness, she narrows the choices pretty quickly.
