And how do we know that if a careful and genuinely open-minded comparison was performed in a $300K system between that power strip and a variety of $500 strips, that one of those relatively inexpensive strips would not provide sonic results that are comparable or even better?
Al, of course, we don't know that, but it is also not very likely to be objective after spending that much money. Person who really believes that ultra expensive power strip should sound better will hear that. There is nothing wrong with improvement thru placebo effect as long as one can afford it. Please don't doubt or conduct blindfold tests since it might ruin perfectly good placebo effect improvement. Just let this person be (that's perhaps what my friends think, seeing my double runs of inch thick speaker cables)
