I guess I need to upgrade the speakers in my iPhone X. I only can discern the differences of random jitter noise from that website link on my iPhone, regardless of file samples.
Yet I fall into Steve’s (@audioengr) camp regarding discerning obvious SQ differences due to a high quality jitter clock or external reclocker that produces ultra low jitter (e.g., 10 psec jitter output at the end of a BNC-terminated coaxial cable) when listening to digital music playback on my home audio system. A digital audio signal having psec-levels of jitter readily manifests itself as an improved analog audio SQ effect on the dimensionality of the reproduced sound field and the realism of instruments and vocals conveyed therein. |
@bluesmen: I have owned both the AA DTI and the SF Ultra Jitterbug. Both are great digital signal reclockers, significantly reducing jitter in the resultant digital stream and yielded greatly improved SQ. I can’t recall the DTI’s output jitter levels, but the Ultra Jitterbug output jitter level was < 40 psec. The EA Synchro Mesh reclocker takes this principle to another level with a reported output jitter level of 7 psec. I can’t recall, but I think one has to have Steve modify the SM design (remove the output transformer?) to get that reduced jitter level. It’s an inexpensive mod.

“I wouldn’t want a speaker with a super wide soundstage for instance, as that would cause too many reflections...”
The above statement clearly shows we’re dealing with a newbie to high-end sound reproduction. I take back my comment about his being a nerdy troll. My apologies.
Stereophile has several publications that explain the nuances of sound reproduction in high-end audio systems. I recommend mzkmxcv check out those sources.

+1, @nonoise, for acute perception of the discourse here.
-1, @audioengr, for making a stupid political analogy that adversely affects my opinion of you.
-2, @mzkmxcv, for being a nerdy troll here. |
And yet do I sense the faint cackles of laughter emanating from the grave of Julian Hirsch having found a new disciple to carry on his legacy? |
It’s not a question whether jitter, per se, is inaudible. The question is whether jitter manifests itself in the audio reproduction of a digital source that is audible in terms of the dimensionality and realism of instruments and vocalists localized therein. Countless companies, as confirmed by critical listening sessions, have demonstrated that reducing jitter to psec levels in digital audio streams greatly improves the sound quality in high-end audio systems. This is largely incontrovertible. |
Words of truth, jerrybj.
The term “placebo” is often used by those who actually know the difference between two or more substances, of which one causes a “non-effect” and another that causes an “effect.”
It seems to me that one cannot have a placebo unless one acknowledges something actually does bring about an “effect.” So one must first acknowledge the existence of a cable, for example, as having a bona fide change in SQ, before a placebo can even exist.
So it’s more than arrogance. It’s stupidity to suggest another’s experience is false or that another is being deceived when the poster typically has no experience with the product(s) in question, let alone the context in which the product(s) resides.
And there are are others who base their arguments on test results that they would likely admit their don’t fully comprehend to even critically adjudge the test construct’s legitimacy. Even more amazing are those who believe not hearing such differences when listening for them on an iPhone proves their point as being universally applicable to all audio systems...well, don’t get me started. |
Julian,
Yep, I spend my evenings enjoying test tones on my audio system.
I correctly understood you stating that you could not discern the jitter level differences with authentic music in the stream. And you then concluded what I stated in my previous post. |
Consider me biased, but one’s opinion that one can’t discern differences in audio SQ from audio streams with different levels of jitter—based upon listening for such differences with an iPhone—does not carry much weight to draw the conclusion that such differences in SQ would not be readily heard in a decent audio system in an open air environment. |
As is the case with nearly all threads here, contributors come in a variety of forms: bias confirmationers, naysayers, impartialists, fiction writers, humorists, trolls, truth-seekers and educators.
@audioengr should be recognized as a patient saint-educator on this one. |
