The microphone would sense a vibration & turn it into electrical energy & if recorded, there would be variations in this recorded signal depending on the particular microphone & recording equipment used. So where does this now lead?
you've left out PLL's . PLL's are wonderful, but they have many real world limitations and susceptibilities. Though they have become much better refined in the last few years, and have been tuned a bit better for issues of audio frequency range. A good discussion of this (a specific USB related case) is in the eetimes story about the development of the PCM2702 that someone linked to earlier.
maybe so, but it ain't likely 😛 😀
In any case, there are a number of good technical sources for info on jitter, clocking, PLL's and data transmission. 🙂
Eclectic2K already pointed out one way that you ignored & there are many others - PS related, cable related, internal chip construction related - I'm sure I'm missing some?
All DACs are susceptible to jitter - it's not required to "construct a DAC with such a lousy timing system, just to see above which threshold that would produce measurable and/or audible artifacts." Look at Stereophile to see the jitter measurements analysis that they print for each digital device they review!
Anyway, my question to which you replied "Is this a stance based on theory or on actual experience?" - was directed to Werner.

I hope Werner will kick in as well, if this is your authority figure and since it might only make you happy if this answered by Him directly. However, some others might have relevant insights as well. Perhaps I have not been very clear in expressing myself, so let me try to do better.
Jitter does exist as a phenomenon, and it can be demonstrated to emanate not only from the mother clock, but also from the circuits and interconnects behind it, as you rightly point out. However, you need to be deliberately or coincidentally totally inept at electronic engineering in order to get any serious amount of jitter (above nSec), either white noise or correlated. Frankly speaking, at the frequencies we are talking about here, <200Khz, I would not know which components to order at Digikey that would allow me to design off hand a frequency dividing network that would show any significant jitter at these frequencies. I would have to integrate jitter into the design, to get anything showable to begin with.
Then, the effect of jitter on the sound quality would flow through the reconstruction of the original wave shape by the DAC. There are orders of magnitude between the sampling frequency used by the DAC, and the jitter time error you could achieve even with intentionally bad design.

No authority figures, just a simple question about his statement. Go ahead & step up to the plate!
My experience in the Brick Lane area was similar- very unadventurous menus, at least for Westerners, and the flavors were similarly unadventurous. I would have dismissed Indian food in London completely (I was living in the SF Bay Area at the time, a hotbed of great cuisine, so might have been a wee bit spoiled), had I not dined at New Tayyabs. Absolutely superb.
I realised a while after I posted it that I was daydreaming about a past tense Brick Lane which is no longer. My apologies - I had a few good curries there back in the 80's when it was formica table tops and hard seats. More recently its been 'gentrified' so barely worth a mention.
It sounds to me as if you've been, to coin a phrase 'showering in mineral water' 😛 Indian food in UK is largely commoditized, not boutique stuff. There are one or two notable exceptions - 'Chutney Mary' springs to mind but I've never sampled it myself.
Ditto. Don't know if that still exists. What I had here in East London was not super spicey, but quite tasty and fresh. I enjoyed it. I didn't want anything that would give me the jitters. 😉
I see this discussion has gone into Food Effect.
Food and Drink are really important when it comes to evaluate a systems performance.... Mine always sounds better after a good dinner 😀

I looked around a bit last time I was passing through in 2008 and it seemed to have pretty much all gone over to traffic calming measures accompanied by lashings of bollards.
Welcome back to the sound topic!
Owning both, I think CD vs LP has a lot to do with who the recording engineer is or the re-mastering engineer. Compression is required for each on most symphonic material. How it is done is an artist versus the marketing department versus (on pre-1970 recordings) the limits of the recording/mastering equipment available.

The problem I hear with most CDs is they are horribly mastered. I have some Mobile Fidelity CDs mastered on Tim de Paravicini equipment that are awesome sounding! So it's not so much the medium as the quality of the mastering equipment and the engineer and producers attention to detail and most companies are in it for the profit and they could care less for the QUALITY. Most companies just set one level and let it rip. If it was recorded on a Studer J37 then you need to restore a Studer J37 to play it back and they are just not willing to spend the extra time and money to do that. Ray
I've got two Mobile Fidelity LP's of steam locomotives that are amazing. Unforunately, when MoFi was performing amazing feats mastering CD's from the original master tapes, I was paying my first house payments, and did without a refrigerator for 9 months I was so stretched. Neither have I ever seen a MoFi CD in a charity resale shop. Pity.
I have scored some C.R. Fine mastered Mercury Living Presence LP's in charity resale shops, lately. I bought as many of these I could afford with my lawn cutting money 1964-66, but my Mother's Top Value Stamps stereo ripped the highs right off. Fortunately, the heirs of the doctors and lawyers with fine stereo hifi equipment are dumping the collections on Goodwill and Salvation Army. Unfortunately, I've got 6 copies of 1812 overture ($.50 each) and only one other title, Durufle playson an Aeloian Skinner organ in NYC: In gloriously mastered in 1957 Monophonic hifidelity. MacIntosh cutting lathe amps they said.

The now not so recent hifi show in Sydney, and visits to dealers demonstrate that the level of enthusiasm and attention to detail by the retailers has fallen off badly in the vinyl area - apart from a friend's budget setup I haven't heard decent LP replay for quite some time - apart from a single effort at that show ...
Interesting...What is the last set up you heard that sound great?
I mean every once in a while, I loop up on you tube for audio shows...and I got to say that from the videos at least, it seems they have pretty good set ups at this important audio shows...
that is why I am curious to know what is your favorite set up and what is the set up that least impressed you and the most disappointed you.
