Our biology isn’t made to subjectively evaluate the sound of electronics. We are notoriously bad at it.You are absolutely right. But when it comes to sound, which would you prefer - better sound subjectively for you or better technical specifications? I personally don't "listen" to technical data.
Spend your time, money and efforts elsewhere: optimize your room, placement, try room correction, measure your room and try to identify issues, and fix them. It will have orders of magnitude more impact on sound quality than a silly capacitor.
