A thought.... who praises the significant, if not impressive, improvements in sound quality that can be achieved by buying very expensive "high end” cables?
Two groups. One - Those that manufacture, distribute and sell these products at a serious profit and Two - those who were talked into drinking the Kool Aid and would NEVER fess up to being fleeced. Actually there is a third group. This group are consumers who gulped the Kool Aid and are victims of the insidious audio placebo effect that causes you to believe you hear the advertised, albeit impossible, sound quality enhancements.
Since virtually no consumer does, or has the capability to perform, an instantaneous AB test (the only kind that are really valid) on the old/new equipment, his (now biased) expectation will allow him the pleasure of experiencing superior performance – even when there is none.
