these audiophile switches are not too pricey... ether regens for instance trade used frequently at $500-600, buy one try it, if it doesn’t enhance your sound, post it for sale, it’ll be gone in a few days
otherwise, one can likely find retail sellers of silent angels, english electric or sotm, aqvox, etc who will do trial periods, worst you can lose is shipping, maybe a small restocking fee
too much brain damage and chatter on these threads - there will always be divergent opinions on a forum, anonymous keyboard jockeys spouting their knowledge from on high, no check on their credibility... it is just the nature of the beast -- so you want to know if something works? go get it, buy smart and learn for yourself, sell it off if it doesn’t perform to expectation
