We already found the fire several decades ago , it is called placebo effect expectational bias or confirmation bias or perceptual bias hence why measurements and -controlled- listening test (ABX or similar ) is used when developing audio . This may be hard to do at home just keep in mind that any sighthed testing have these side effect and they are not optional they are always there there is no golden eared way to mentally block this. So skepticism is good here "I heard what" ? The perceptual bias effects is in case of subtle differences bigger than what you try to assess . Hence why people hear differences between properly designed digital transports in sigthed tests and report anecdotes about it while in the real world such differences are extremely unlikely and the bias effect is extremely likely. People will always experience differences in sighted test of anything that is a proven null, it migth be cheese or wine or whatever . This effect has been used to great effect, there is an classic experiment where people in a workplace had access to a knob where they could adjust room temperature in a small interval (so they where told ) and they enjoyed their workplace much more, this sense of control was very beneficial. Of course the knob did absolutely nothing . And this one. " you hear a difference between say, a $5 USB cable and a $50 one, then it is probably not worth the bother to blind test, and I would just buy the $50 one and be happy. " The snake oil sales guys love customers like you :) when you are accustomed to pay 50$ you may later on "improve" this with a say 100$ one -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
