This thread has taken a less threatening direction than most of those dealing with the usual "prove it sounds better" versus "I hear one is better" threads. I think this is largely because of Winstonsmith's use of DIY cables and good defense of the importance of achieving accurate sound. But in reality Dlanselm's personal experience really has no impact. Most of us still proceed with using the components and wires we hear as best and can afford.
Personally, I see no benefit with double blind audio tests, but single blind tests are fine. Who cares if the person running the test knows which wire is which? I have participated in several of these with in one case where a Bozak preamp was preferred by several prominent designers of other preamps. But these blind tests all used matched volumes but lengthy listening comparisons. Also none of these were seen as anything more than entertainment. I am certain no one ran out and bought a Bozak.
I have also participated in short duration same/different DBTs. I know the confusion that comes with these tests. I certainly found them curious and hypothesized why the strange results. Then I realized that the tests must invalidly capture what we mean by sounding different, especially in one where most of us then compared the two amps involved still in a blind comparison but with longer listening comparisons and the opportunity to go back and forth between them. We all now preferred one of the amps. To me this is a more valid comparison and certainly yielded different results.
Again, all of this is largely entertainment of little relevance to a buying decisions. Dlanselm obviously did change his mind as a result, but I doubt many of us would. I certainly found no interest in buying the Bozak although I did seek it out several times at audio stores. I also did not buy any of the other preamps in the test.
Why there is this constant debate about DBTs perplexes me. Frankly, I have more trust in my ears than I have in others.
