I saw synchromesh and thought this thread was about a mashup between SPDIF and automobile transmissions.
I'm so disappointed.

If there's no correlation between two methods of collecting data then how can you automatically assume that one of them is without fault? Shouldn't both be scrutinized further?
So be careful of thinking you are continuously improving things. Pause and run a controlled, blind test. It is so easy to chase your tale thinking what you physically improved, must have had an audible difference. Your ear+brain are one of the most unreliable tools here when detecting the results of the work you are doing. That is just the way they work. It is called being human. Our brain is programmed to make us optimistic. It is dying to find reasons to celebrate. If it were the other way around, we would all die of pessimism and negative thoughts!
Such a device is the Turbo Encabulator....a mashup between SPDIF and automobile transmissions.
He doesn't actually. Not that it matters but he has the last generation 2700 Audio Precision analyzer. I have the newer generation. The 2700 is an excellent analyzer though and is only bested slightly by mine:
Mine is the APx555 in black and his is 2700 in blue. Graph is from Audio Precision.
I did, using the Intona USB isolator and different USB hubs, as proposed by Archimago in his blog. No difference with the RME Adi-2 Pro that I could detect in a blind test. Also I could not detect the difference of the small digital processing bit error that I found in the RME's firmware vs. when corrected (you may have seen my thread here), and this error I would naively assume to have a much larger impact than any jitter.
I agree.My opinion is that it shows that lots of people like the sound of distortion
I agree.
These days, I find it ironic that rock-centric audiophiles seek minimum distortion audio gear to play back recordings made using extreme distortion. Amplified distortion is essential for most "heavy" or "hard" rock and roll music. Rock and roll climbed to its heights of popularity fueled by electric guitar distortion - things like digital fuzz and grunge, vacuum tube amplifier distortion, and damaged guitar speaker distortion. Linc Wray's "Rumble" is one of my favorites of this type from the days of my youth, and I never knew that he had punched holes in his speakers to get the sound on his classic song. Great article on the subject HERE.
Jazz guitar sonic styles, of course, range from "clean" to "dirty", and jazz guitar is one of my favorite genres.
And of course, I think that we are all aware of the more soothing and warmth of odd-order distortion is preferred by many vacuum tube amp fans for many genres.
To each his own, and may everyone enjoy their favorite flavor/style of playback. Mine happens to be listeing to a clean low-budget system that allows me to experience an uncolored reproduction of the recording - warts and all.
Whatever it is, it must be high-end with all those buzzwords.That's analog!
The dingle arm should be the clue
If you claim that any signal or noise below -110dB is inaudible anyway, then what's the point in having better equipment?
Not much different than normal jitter. The only difference is that one is truly random and the other is based on the music (but it’s not harmonics), both result in a raised noise floor. Jitter spikes hugging a main tone are less forgiving. So again, a J-Test is even worse than real jitter, it tells us how a DAC performs given worst case scenario jitter (flipping all bits).Random jitter is like noise events that occur randomly.
If listening via an amp with poorer than -110dB distortion and speakers with, at best, -60dB of distortion you are genuinely unlikely to hear anything like that upstream, particularly if your measuring kit is the ears listening to speakers.If you claim that any signal or noise below -110dB is inaudible anyway, then what's the point in having better equipment?
I'll ask again (4th time without an answer)....
What are you hoping to learn from Amirs measurements ?
What parameters/signals do you exactly want measured ?
Not much different than normal jitter.
I agree.

Did you take some kind of exam with independent grading to confirm this? Have you for example passed online blind fidelity test that others could not?I never claimed that. I only know that my own auditory system is pretty well trained after 38 years.
Here is what we can do: absolutely dismiss any sighted results of such testing. You are guaranteed, let me repeat, guaranteed to produce wrong results. This has been shown before and can readily be repeated. Here is a local and one of the highest end champions of cables, losing such in blind testing whom you know:You cannot say with any certainty that a particular component or cable sounds good or bad or one is better than another using only measurements without this correlation and relevance being established and proven.
Since you are on WBF forum Frank, this should resonate with you. You know Mike Lavigne. For those who don't know him, he has a super expensive system and cherished as one of the highest high-end audiophiles out there. Like you Frank he is convinced that what he perceives in audio is the reality.
Well, back in 2011 he was so sure that he could tell his MIT Opus cable from others that he accepted a blind test challenge in his own home with his gear. The results are were this: http://www.avsforum.com/forum/86-ul...41184-observations-controlled-cable-test.html
"So our results with Mike as our listener were clear: for this particular methodology, Mike could not accurately identify a difference in the cables."
Here he was so sure of his ability hear differences in cables but the moment all but the sound of cables were presented to him, he was unable to do so.
Mike posts this about the experience: http://www.avsforum.com/forum/86-ul...184-observations-controlled-cable-test-2.html
"yes; i have, to some degree, changed my perspective on cable differences....but...my mind is still processing the results and what they mean for me. i hope that i can coherently relate the various thoughts that go thru my mind. as Chris mentioned; the controls were successful at keeping me from knowing which cable was which. for each test i felt confident about my choice (except #6...see below).
[...]
when i made my choice known for #8 i was confident that i was 100% for all 7. then my friend Ted said 'that's it.....test over'. we had discussed prior that any result 7 out of 10 or better or 15 out of 20 or better would mean a positive result and to continue. once we got to only 3 out of 7 it was clear that we were not going to get a positive result.
why did i fail?.....or put another way.....why did this test show no real difference? was i overconfident?
yes; regardless of the eventual answer i was not respectful enough of the challenge.
[...]
in my mind i am not confident that i will ever be able to hear reliable differences between the Monster and the Opus to pass a Blind test. OTOH i am also not sure i won't be able to do it."
After countless years of believing in cable difference through the same type of experiences you talk about, he was shown to be completely wrong.
Sadly he has forgotten all of this now and is back to believing in his faulty methodology. Which is fine but in this forum we don't do that. We learn from such data and advance our knowledge of proper audio evaluation.
