It depends. If everyone has had a true audio logic hearing test and demonstrated perfect (human) hearing profiles and is under 30 years of age, then perhaps there is justification for spending thousands of dollars on cables, capacitors, power cords, etc. OTOH, if one has spent hours in rock concerts, and constantly wearing in-ear headphones, and is over 50, then it becomes pretty speculative as to whether there is placebo value or actual perception going on. I'm personally happy with my placebo audio improvements. The system sounds great!!
