Consider this article in 2018:<br />http://archimago.blogspot.com/2018/08/demo-musings-lets-listen-to-some-jitter.html<br /><br />Therefore don't be too concerned with these very subtle timing anomalies and IMO no point spending too much money justArchimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-86819871059142772052019-01-23T03:52:12.213-08:002019-01-23T03:52:12.213-08:00wow and omg. this is the article i've been loo...wow and omg. this is the article i've been looking for. i have a dcs scarlatti dac fed by squeezebox touch via spdif coax with transparent audio 75ohm digital cable. your article implies to me that i may not get out the best of the dcs dac without their world clock unit. is that so? many thanks in advance.Anonymoushttps://www.blogger.com/profile/16124551842851010817noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-75540803741674143742018-10-21T03:42:19.633-07:002018-10-21T03:42:19.633-07:00Hi..sort of an old post, but still highly relevant...Hi..sort of an old post, but still highly relevant.In your opinion, the difference in sound stems not from jitter but variations in the word clock. Riddle me this then: how come that I hear a difference between MacBook Pro and HiBy r6 when I send their usb output to an Eitr re-clocker? Theoretically, the Eitr redresses the signals with the same clock information.<br /><br />Thanks!

I’m wavering on a Mutec MC 3+ USB – to be connected to either HiBy R6 DAP or Nativ Vita; AES from there into my active subwoofer. My common sense tells me any audible difference will be the product of placebo…But of course, I’m not sure.

Alas, unless I have more time to delve into this, I think it's OK to leave it since the differences are so miniscule that there's really no meaningful difference.<br />Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-1040010872491985132013-08-01T08:19:50.649-07:002013-08-01T08:19:50.649-07:00Isn't it entirely possible that those miniscul...Isn't it entirely possible that those miniscule differences can be attributed to chance? No measuring equipment has 100% reliability. You would need repeated measurements to ascertain the standard error of the mean and then a bootstrap simulation in order to accurately represent individual differences between those sources for a high alpha level of statistical significanceGeorgioshttps://www.blogger.com/profile/07745247845018730696noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-7142104286445314292013-07-20T17:38:29.078-07:002013-07-20T17:38:29.078-07:00One more thing...

My suspicion is that these FR differences are so small, it would be beyond the capability of DiffMaker since they only would show up with extreme high frequency content which would push us into synthetic test scenario again as you noted above with sawtooth waveforms.Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-21912497661497211452013-07-20T17:34:54.193-07:002013-07-20T17:34:54.193-07:00Thanks for the comments Dennis!

...One additional comment in regards to Diffmaker. <br /><br />Another benefit of the sawtooth waves is that I have found this to be the easiest type of waveform for Diffmaker to time align. So even a half second of sawtooth waves at the start of any compared tracks is beneficial in the use of Diffmaker.

It will show if the residual null is timing or a level difference. It also will let you calculate how much difference in timing there is.

I would like to ask your opinion about high resolution audio files like 96/24 or 192/24 (I know it's off topic but I didn't know where to post). I think there isn't a really audible improvement among standard 44/16, taking into account also your mp3 test.

Of course we are mostly looking at the essence one and perhaps repeating the test with the UD-501 can help draw a more 'certain' conclusion.
