I'm still wondering why you're not getting higher correlation at high volume. It suggests to me some limiting factor, maybe some clipping or distortion at high volume, that is masking the effect until you get down to lower volume levels. In my tests the decrease in correlation was exactly equal to the decrease in volume. I can't explain your result. > I'm going to concentrate now on different transports/same DAC (the > elusive search for the sound of jitter?) and also I want to try > different interconnects between DAC and pre-amp. I am skeptical that ADM is sensitive enough for that. But I am still not sure if I am using it to maximum effect... would like to see less variance between runs. It would be cool if somebody made a software jitter simulator so you could just turn it up until it's audible. Anyway, if you're not convinced about the SNR effect, there are much simpler tests that you can do for that, eg a sine wave and some analyzer software. Somebody did this with an SB3 once, and got the same result that I got with ADM.
