Re: Um...

"If you can't switch quickly and cleanly under listener control, there is presently no clear way to keep the best in test sensitivity."

I have to kindly disagree here. I think listening is no different from wine-tasting. (Tasting one wine right after another gives the taster no clue in regard to the later sample.) If component "A" happens to be utterly fatiguing to listen to, the "fatigue symptoms" do not just go away shortly after switching to component "B". So the "ill effects" of component "A" will seem to be present in component "B", even if component "B" would otherwise not fatigue the listener at all. (And there is a good chance the listener could think component "B" is the one causing the fatigue. I think this is why people often "fail" DBTs. Jon did allude to this indirectly.)

DBTs *can* be done with longer-term listening and with breaks between listening to each component under evaluation. I personally think the results under such methodology would be far more relevant and valuable, because listener satisfaction will be figured into the evaluation. And in my opinion, listener satisfaction is the single most-important parameter in evaluation, be it "sighted" or "blind."
