I've never considered listening to anything as an arbiter of quality, only measurements do that. Consequently, on more 'subjective' forums, I've been labelled a Measurebater!... especially the advice on "you should really listen to one of his designs sometime". I didn't know this would've been forward or demeaning, but I will watch out for sure on what I say. I really just want to read stuff anyway. I didn't mean to make anybody feel bad.
Nevertheless, however competent (or otherwise) a design might be, I would always measure it first, and then if it passed those tests as reasonably competent, would I bother to listen to it. I've never bought anything after listening to it without corroborating measurements.
