What would you like me to do? I listened and I can't hear it. There is nothing more I can do without information from you. So the next step is you need to do some very simple tests which we can reproduce here. The first we're suggesting is to make recordings using a sound card with s/pdif. That should take you about five minutes once you have a suitable sound card at hand. Forget about jitter. Jitter is simply clock noise, and is easily measurable with appropriate equipment - as easily as we can measure the noise floor of a DAC. It doesn't work the way you think it does. It doesn't change when you press buttons on the remote. I have taken extensive measurements of SB3 and Transporter's jitter characteristics, and under all circumstances it is a perfectly gaussian distribution with no detectable correlation to any type of system activity. You see, there is nothing I can test for you, because I have already tested the product and what you are describing is not consistent with what I know about it. But I am open to any evidence to the contrary. Again, the most plausible explanation is placebo, and the more people agree with you, the more likely it is! That's the whole point of it. You believe what you are suggested to believe. It is a well established concept in medicine (and elsewhere), and in audio it works exactly the same way. If you don't believe me and you want to do your own jitter measurements I am happy to tell you what equipment to buy and tell you how to set it up. It'll run you about $20K. Or if you just want to look for any difference at all, you could use a sound card to make analog recordings of a high frequency sine wave and compare the side bands - this is not difficult, and your measurement guy probably knows how to do this. Finally, please note that in my discussions with you I have not cited how many people agree with me. It's completely irrelevant. Everything I'm telling you is observable and falsifiable. You don't have to believe me. You can test it yourself. Your statements, however, are not falsifiable because I can not test them - I don't have your ears. A statement which is not falsifiable is not necessarily true. You really need to understand that if you're going to make any progress on this. Good luck, I have no more ideas for you. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
