We need not waste our time debating the physics (or lack thereof) of MD products. I've no problem allowing for physical phenomena whose mechanism we've yet to understand and quantify.
So let's cut to the chase here: If MD products make a difference, a blind listener will be able to identify that difference. End of issue.
