DBT ... dont'ya just luv that.
So often quoted (and the naysayers/anti-snake oil brigades favorite term) yet hardly anybody has ever participated in one
DBT is a part of the scientific method and is designed to 'prove' certain assertions in as rigorous scientific manner as possible.
It is rarely carried out in hi-fi for the simple reason that it is complex, time consuming and expensive, and hi-fi is an unimportant hobby.
If people stopped making wild claims for what they hear in sighted tests, then I don't think that DBT would come up at all, as is so common these days, people do not let a lack of understanding stop them from putting forward their views, often most aggressively.
I have taken part in blind tests (not rigorous double blind) and the overwhelming outcome of such listening is just how difficult it can be to hear differences that were, to coin a phrase, night and day in sighted tests.
I make no other claims for what you can and can not hear in blind tests, just that is rather eyeopening should you ever have the chance to take part in one.
I did.
With this very publication.
Except that I don't think these tests are always that telling. - They are usually carried out in unfamiliar surroundings with unfamiliar music on an unfamiliar system, often there is still stress from finding the place, commuting and the test itself ie. getting it 'right' in front of other people present.
I think it was Townshend that once carried some tests out on Alpha Waves in relation to hifi. I can't remember exactly but it was something like twenty minutes of total relaxation required to chill out sufficiently to have anything approaching a meaningful dem of equipment. Hardly the environment of a DBT in strange and unfamiliar surroundings (nor a demo of equipment at a dealers with the pressures sometimes involved).
Perhaps if the above is carried out in the system owners home under controlled conditions but even that is not as straigth forward as it seems as you quite correctly pointed out.
Far to much faff involved plus this hobby involves listening with our eyes too. No matter how good something sounds, if it looks horrid in the surrounding in which it will be used its often no good to the owner.
So if something seems to sound better because it also appeals to the other senses ... it does sound better though it may be difficult to convince others likewise.
