Seems like everyone has a home brew for eq( enhancing ) headphones SQ on this forum. As a science based forum , the directive to just listen to changes does not get me very far. Once someone creates EQ adjustment list isn’t there an objective way to measure the suggested SQ improvements? The actions of amateurs and enthusiasts and electronics designers based on personal preferences does not instill a lot of confidence for me to try their various recipes. Why don’t headphone makers provide various EQ scenarios for their products? Just curious…
