Most of the Golden Audio fools blew the audiograms results away by the time they were 18 now adays. In a chamber they would be very lucky to come out at 500/17,000 if more than 25 years old and less if they have been listening to th O2 free gold monster plated cables for a few months or so. They are out of it. They only hear noise not MUSIC. Hank KN6DI
