I know its also hearsay to say that human hearing hasn't improved sense the 70's, but I really don't want to punch that bees nest called audiophiles golden ears. ;D
Can't help myself, they still selling $100+ caps to those guys? How about those $300+ 300A Western Electric 7 watt tubes? $500 AC power cables? $50 Wood thingees to place on top of your speakers?
;D
