Aren't the sidebands and the width of the spread at the base more important?

Am I missing something?  I don't see an 11khz spike with the Wyrd + ODAC, but I do see fewer symmetrical sidebands with Wyrd.


Sorry 12kHz...

Without the wyrd the 12 (thus not 11) kHz spike is narrow and exactly at 12kHz.
Assuming what we see is an average over a certain time period this means that the 12kHz is mostly stable at 12kHz (so doesn't jitter to the left or right)
On the ODAc + Wyrd you see most of the freq is exactly 12kHz (masked by the grid) but part of the (what should have been exactly 12kHz) seems to be fractionally higher.
So it 'jitters' between 12kHz and slightly higher.

The base width doesn't seem to change though... the stoner seems better than the ODAC (if measurement conditions were the same).
So if the base width is an indication of LF jitter amount the Wyrd doesn't seem to 'improve' anything in that aspect.
In amount of noise ... yes.
This too is very dependent on the analog circuits behind the DAC, the situation and the source as well as mains quality amongst a few other things.
What works for person A may not do anything for person B.

The stoner shows a substantially lower amount of noise with the wyrd so seems to do its job there.
No difference in jitter.

I see that now.  Totally missed it before.

Not all of that is noise though.  The sidebads which are symmetrical on either side of the center frequency represent high frequency jitter while the spread of the base represents low frequency jitter.

I used a Schiit Wyrd through a noisy EMI DAC and it didn't do anything to help it. I also didn't notice any immediate differences otherwise. Not saying it does nothing, but I don't see any reason to purchase one and this other device I don't see any advantages to either.

I can't remember the source of the noise or whether it was more of measurement artifacts but I would not nitpick with the noise too much since the more obvious reduction in sidebands seems to correlate(or at least I feel so) with my favourable impressions of using such devices.

Personally I find isolation of common mode crap a little less priority though to note, in the environments we listen in especially those with PCs, pumps, multiple fans, more of that crap may(or not) find its way into the system and thats where common mode isolation comes in handy.

Also with the Geek Out, EMU0404 I find zero change in the performance with the Wyrd in the system whether subjectively or in measurements. I use with the GO more as utility though.

Wonder if SMPS noise of the Uptone would be measureable, I had no problem doing with the EMU0404 before I switched it out of a LPS.

A newbie non-engineer here so apologies in advance. I'll introduce myself on the original thread one of these days.
But this thread got me curious because I've been thinking of purchasing a Wyrd.
   I know you folks are saying that certain frequencies are changing in intensity but I see a lot of chatter about timing in the audiophile press. are they two separate things altogether? If not, can somebody explain to me what it means?
    And can it be applied to devices like the Wyrd? I hope I get this across correctly but let's say for e.g., if the wavelengths are different in intensity with and without the Wyrd, is the intensity AND number of waves hitting our ears going to change?

No one really knows what exactly is going on with what measurement other than the jitter spectrum. That is why the product is called Wyrd.

I was one of the first Regen (green light version) owners, and it has made a positive impact on my Gungnir.
better clarity in terms of bass definition and some detail extraction improvement.

music was also slightly "louder/clearer" despite never changing amp volume knob. a commonly reported audible change others at CA reported.
the Wyrd + Gungnir squashed depth of sound stage a tad. (ie. backing vocals brought forward).
Regen did not squash the depth at all.

Just got in a Uptone Regen Amber today. While I can't speak to it doing most of the above (I've only had a couple hours with it), I can say that "music was also slightly "louder/clearer" despite never changing amp volume knob" is spot on with my DS Gungnir Gen 2.

I don't know if it's clearer, but it is definitely louder. So much so that I purposefully searched the forums to see if anyone else mentioned hearing it. It's almost on the order of removing an inline attenuator from the signal chain as far as magnitude of difference.

Can anyone venture a guess as to why that switching from Wyrd to the Uptone Regen might cause that volume difference? I don't know what I was exactly expecting when I bought the damn thing, but I certainly wasn't expecting that.

No measurable or logical explanation. It's WYRD isn't it?

Maybe less USB packets being lost or lately assembled or re-transmitted (because of error) resulting in better jitter characteristics, thus allowing peaks in the sound-waves being more naturally concentrated and focused rather than fuzzed out.


Note: The explanation above is purely audiophool speculation and BS. Worthy only as marketing drivel.

Honestly that seems fishy to me. Almost makes me wonder if they tamper with the packets, bumping the amplitude value.
