Do you have any evidence of sound improvements from a clock? There are lots of claims to that effect, but no actual evidence I'm aware of.

Jitter has to be pretty high before it becomes audible.
No I have not the measurement equipment to measure but has replaced clocks in DACs with notable effect especially in the low frequencies and now that here there is measurement equipment available why not measure in range where there is difference in clocks.
What is your opinion level when it is becomes audible with phase jitter?
 
...but has replaced clocks in DACs with notable effect especially in the low frequencies...

Is there evidence of this beyond anecdotal?

What is your opinion level when it is becomes audible with phase jitter?

I believe that it has become a boogeyman used to try to sell people on fancy clocks.

Here is a site that has varied levels of jitter that you can listen to. At what point is it audible to you?

I listened to the sines only. Couldn't make out a difference between 1 (original), 4 (2µs RMS periodic) and 7 (8µs RMS periodic). Everything else was "dirty".

@Neslo1108 : same?

BTW, Welcome to ASR :cool:
 
That's in µSec! Clock jitter is in the order of pSec. Even 100 pSec is 0,0001 µSec, so orders or magnitude difference :eek:

Well. Then i guess it doesn't matter to me.

Not many people can say this: clock jitter is not my problem! (-:

I listened to the sines and could only hear noise at 8µS random as background hiss. All others were inaudible to me. The music masked all situations. Really, any device less than 1µS jitter can for all intents and purposes be considered jitter-free for the vast majority of people. Just like anything lower than 115db SINAD.
 
the jitter that needs to go down below -160db
but the cheap cybershafts have -140db noise floor as standard.
but on the other hand, phase noise 106db 1hz at 10hz 125db.
it is heard, not measured, better bass, midrange, treble.
I have mutec REF10 as -170 db noise floor jitter, as well as phase noise of -150 db 10hz.
and 1-100 Hz 22 fs down to1fs
it sounds very transparent, on a gustard x26pro.
the k2 Ultra low noise clock synthesizer, does something to the sound.
gentle treble, with good transient.
midrange is top class.
the bass is actually real, good on transients.
it has been listened to by 4 people, in a blind test.
listened on neumann 310a studio monitor
 
US $1,457??? I built something like this myself for a few 100 Euros. No snake oil alert!

1) The "handcrafted cottage industry" (AKA: DIY) look is fine, but you need to spend an extra €50 to silkscreen a flashy logo on the front, preferably with some irrelevant but impressive-sounding reference to a precious metal.
2) OMG what happened to the feet? If you want to be taken seriously you need to spend twice the cost of the components on some fancy footwear with spikes, exotic rubber compounds and large chunks of metal. Extra points for only using three feet (as Cybershaft did) so it will tip over if you press on a corner.

'Listening' tests will easily show the enormous benefit to be gained by these two additions.
 
I have singxer su2, with cybershaft Platinum 10mhz.
have noticed. with Accusilicon AS318-B.
is a little out of phase, not much,
cybershaft Platinum is phase, absolutely perfect.
it may well be jitter, no better than Accusilicon AS318-B.
with cybershaft Platinum is phase, an advantage.
it can be heard.

Absent valid testing, any noise heard remains hypothetical. And I mean "noise" in the colloquial sense.
 
Now I am wondering what non-colloquial noise is...
When you convolve it with colloquial noise, in the long term you get 0.
