Anti-science is very popular with the devotees of thermionics in
particular
where the proponents often simply dismiss the relevance of the
scientific method entirely. Graham

I think the words you are looking for are "non-science", and the reason
you've pulled "devotees of thermionics" out of a very large hat may be
because they are more discriminating and require further degrees of
sound quality than the average ss user.

So the fact that they use their ears to discriminate is "anti-science"!

Would you go on to say that boys who select their girlfriends on the
basis of looks are "anti-science" because they haven't considered the
compatibility of their DNA? We're on a very slippery slope here. I
could go on with further examples but you get the point.
