Women have smaller ear canals than we do. They are more sensitive to frequencies above 3000 Hz. They are also more sensitive to what they hear. At night the tiniest of noises will wake a woman up while we continue to snore on. I think in nature this has to do with their child protection instinct, their early warning system. This is also why they like being up higher (SUVs) They are uncomfortable with loud music because it defeats their early warning system.
As for the DACs your example is anecdotal. In and of itself it does not mean much. Certainly, DACs have improved. The early CD players were annoying.
As for phase you have to know what to listen for. It has to do with imaging and dynamics not sound quality(like brightness or bass heavy etc) Hook up one speaker out of phase and listen to what happens. Have somebody behind a speaker hold the leads in place and switch polarity immediately on your demand so you can quickly A+B. The punch disappears and the image collapses. All this can happen to varying degrees at certain frequencies. I think you have to have lived with a system that is phase correct for a while to know when something is off. My speakers are one way ESLs and the subwoofers are corrected in phase and time to match the ESLs (actually it is the ESLs that are delayed) You always tend to compare other system to your own. A big system is going to sound more extraordinary to a person with a small system than a person who already has a big system. If you do not have a system that is phase and time correct it will be hard to notice when other systems are phase and time correct. All of us learn over time how to listen as we gain experience.
