Yep, 1960's 1970's great stereos, great rock music and too much listening with good quality headphones to fantastic sounding 33 1/3 LP stereo records. That is was affected my hearing is my guess. No music today even comes close to the high quality of stereo equipment, LP's and fantastic recording artists back then. I mean nothing today will top that period of music in my opinion. Too many vocals today go through the autotune to make all the female singers sound identical. I have over 300 33 1/3 mint condition LP's that I still listen to on 1970's stereo equipment. But I don't do headphones anymore. My wife says I should sell my LP's because they are now bringing top dollar on eBay.
