The opponents of DBT in audio (well the more rational ones who have spent some time thinking about this anyway) argue that somehow DBT forces an "artificial experience" on the listener, in other words, the process of being tested destroys the highly subjective and somehow ephemereal emotional experience of listening to music.

My argument to that is: why not just cover the components in anonymous looking, unmarked grey boxes, with little slots for the cables to go through and then let the subject use them as they would any visible component, for as long as they like (a few months even).

Anonymous grey boxes don't cost that much.

I think that vested interests in audio (most manufacturers, and the subjective magazine reviewers//editors) simply will not do this because they are scared of what they might find. Otherwise, don;t you think they;d be doing this & shouting the results all over the rooftops?

So they attack DBT. It's amusing to see. Aczel is the only one who has no fear of speaking the truth as he sees it.
