That sounds as appetizing as a beer float.
I don't find the results of these studies to be surprising at all. The wines are not so different that one can repeated tell the subtle differences between a 90 and 95 rating. Also, there are all sorts of psychological factors, which affect a taster's impression, going on. I often find that the wine that knocked my socks off last month is only just good this month.
I think it would be much worse for audio. With amplifier and sources, the differences are much more subtle than between wines (IMO). If reviewers (and all of us) actually did controlled blind listening when searching for equipment, I suspect we'd all save a lot of money. Of course that would spoil our fun, so we don't do it.
