What black dots?

The only way to get rid of those problems is if people can't see what cable they're listening to. No matter the methodology, no one has ever passed a blind test. The problem isn't the methodology. |

(b) There is something about blind testing that we don't fully understand yet, and it makes passing them difficult even though we should pass. |

I still believe this effect is much clearer with a better system, but the original obvious "new" quality is forever gone. |

My current HP system is the best I've ever had (thanks to the DNA Sonett amp and other improvements I've made since then). I am hearing nuances in music that I haven't heard before in an audio system. The weird thing is, when I drive around and listen to the crappy system in my car, I'm hearing similar nuances. This new HP system has gotten me all excited about microdynamics: the expressive potential in small changes of dynamic. I didn't realize how much I cared about microdynamics until I heard this HP system. Well, now I'm hearing subtle changes of dynamics in my car stereo. I'm hearing them in my freaking clock radio! Let me give a visual analogy. Suppose that you love cats, and you found this particular picture, which you have been enjoying on your wall for a while: Later you discover a better, in-focus version: To me, the cat in the first picture appears to be looking slightly downward and seems a little dull-eyed. In the second picture, he is obviously alert and looking straight at the camera. For me, having seen the second picture, it changes my impression of the first picture. I can't forget any more how alert (and cute) this cat looks. I get that impression from the first picture now. This is an obvious example, but more subtle examples from audio abound.

Did you get to read Wavoman's explanation of what happened to me in my Conundrum thread? I couldn't have been more convinced that the two DACs had different sound signatures.... until I A-B'd them through my GS-1. It was a humbling experience. Btw, I read your comments about the DNA amp and was wondering if your DT880s were '03 or '05? Regards USG |
First, I'd like to say that until you volume balance you don't have a clue. Second, unless you can A-B during a track, you're relying on your audio memory, and I don't care who you are, your audio memory is lousy, and by the time you disconnect and reconnect cables and reset the volume you have lost your reference point and any impression you think you have is extremely unreliable. This has happened to me more than once and I'm here to tell you that Crow does not taste good. All my initial impressions were nothing more than imagination. |

The DT880s are the 250 ohm 2005 version. Well, I certainly acknowledge that expectation bias is there. To me there are several possibilities, and I find them all worth thinking about. I think there are many good reasons to believe that the test protocols themselves the the problem. Here is a quote from you: It appears that you used a quick-switch comparison technique, and perhaps even switched while the music was in progress. You also talk about "audio memory" in a certain way. It may help to clarify my position on "audio memory"--see this thread: http://www.head-fi.org/forums/f133/r...-sound-430023/ The particular qualities that set DACs apart in sighted listening are qualities I cannot perceive during a quick switch test, especially while the music is in progress. (If you switch while the music is in progress, you are not controlling the signal you are using---it is changing even as you switch.) If you don't switch while the music is in progress, but your concept of audio memory is "short", then you have to use small snippets, which also completely obscure the musical qualities I care about. So out of the many interesting explanations we have for your experience, and for my experience, it's possible that your test protocol was creating an insensitivity to the very things you wanted to test. Let me clarify: I am not opposed to blind testing. I will be conducting some this weekend, now that I found a friend who is also interested and can help me switch cables while I'm not looking. I just think that we need to find sensitive protocols and I'm not convinced anyone has done a good job of that. |
