I think so, which is why I'm discussing this here. We need to be honest with ourselves about how we each make decisions. I've thought "wouldn't it be cool if I could make a DAC with an automatic phase error measurement system that could tell us when different tweaks had different effects" but y'now at the end of the day I don't think very many people would actually buy it, and likely not enough to go to the effort of commercializing --I don't underestimate that work Custom room treatments for headphone users.

He proposed putting it in an inexpensive DAC design (one that would sound quite good anyway). It would be interesting, but I'm not in a rush to put such into production. jabbr 1 UpTone Audio LLC Link to comment

How many of you folks have measured noise in your systems with and without these components, then conducted thorough, reliable blind tests to make sure any measured differences were audible? there are two forms of noise in this complex situation - real and imaginary -- voltage & phase Custom room treatments for headphone users.

Jud Posted June 23, 2017 Author Share Posted June 23, 2017 2 hours ago, pkane2001 said: I'm currently using an ethernet USB extender that allows me to place my PC in another room. As a side benefit, it also provides some level of galvanic isolation, regeneration (hub) and a separate source of power to the outgoing USB. In a blind test (and even in a sighted test) I can't find a difference between the ethernet extension and a straight, short USB cable. My chain includes an SU-1 DDC, so perhaps that eliminates some of the differences that would otherwise be audible. I'd be willing to try the Corning cable, as well. I'd probably want to see if the two copper wires could be interrupted and fed with a separate power supply. And yes, I will conduct blind tests to confirm if I can really hear the difference. I also do try to measure all new components for noise and jitter at the output of the DAC, but admittedly, my measurement equipment is not the best: a Behringer 24/96 ADC feeding an older Macbook with a Toslink input. Yes, but what kind of blind test? Not something that involves switching in 2-4 seconds, surely? I know these sorts of “nudge, nudge, wink, wink” blind tests aren’t subject to some of the same problems as sighted ones. But that seems to me akin to saying “I may not be taking any drugs to help my arthritis, but at least I’m not wearing one of those stupid bracelets!” I’m interested in what attracted you to the idea of the SU-1.

At risk of straying off-topic, in the case of scientists, that number is comparatively few (about 7% of the members of the National Academy of Sciences). In the (admittedly extreme) case of Francis Collins, it does make me worry about many of his other beliefs. Link to comment
