I found that my DACs with built in USB performed better with transports than they did by themselves. Now this is not scientific evidence of anything. I was simply agreeing with you on that subject.
You spin a good yarn but the only empirical evidence you can offer cannot be separated from psycho-acoustic phenomena. I remember reading nick charles' thread and think that an attempt at measurement is better than bandying about unproven theories and impressions of something you think you may have heard.
I am well aware about the placebo effect. However, when my subjective findings correlate with a scientific fact that I wasn't aware of before, I say it is not placebo.
Personally, I think that people that are the most affected by placebo are people like you, who think they know the science while they don't. You a have a limited knowledge of science (jitter to be specific) and you are trying to convince yourself that any differences you hear is not relevant.
Anyway, it doesn't seem that you tried to read any of the research material I gave a link to.
If you were really objective, scientific and open-minded, you would have read and commented on the links I have provided you with.
If your sole itent is to say that usb cables are the same without providing any real interesting insight whether it is by subjective listening or based or on scientific measurements on jitter, I honestly don't see why you are posting on the subject.
It is because of people like you who don't take the time to research or to really read other people's posts that I had decide to stop posting on the subject.
So please, as the thread OP, I am asking you to do one of the following:
1. Either you provide REAL scientific insight into the differences (or lack of) between different usb cables;
2. Either you provide your own subjective exprerience on the subject;
3. Or, if it is just to say that all of that is only placebo and only due to a "psycho-acoustic phenoma", I will ask to stop posting on the subject and read the following : http://www.head-fi.org/forums/f46/do...-forum-450574/
