I understand. You probbably know how original was sounded. And now with caps... what can you tell? What is the differenc? If it goes to thin clean sound like sample 2 it is not the right way for me.
That was all I was answering, someone compared A1 and A3 and I found the .5dB difference there.
You mean A1 is higher in level? But the sound I heard is not about which one is "stronger" so even if the other one is louder it wont change the character of the sound. It's bout missing tone in A3. That's why my first post in this thread had title "Throwing the baby with the bath water"
It should be noted that Pano also compared levels and found an insignificant difference. Pano?
Something is screwy.

I understand what the objectivists want. I also understand that louder signal will have more "impact", "dynamic", "sonic" (so it will not be "controlled" as the louder one will be better). But I also know other sound "characters".
But I think it is easy to switch the relative loudness between the 2 files? Or to put other controls to compensate for that loudness difference?
Sorry we're talking A1/A3 only here. Beside the point, I don't hear any of this other stuff level or not, none of these files is anymore than trivially different than another. In any case Joe is flogging the jitter issues and these tests obfuscate any jitter differences. As I said this is a train wreck waiting to happen.

Joe,
That's just close in (to carrier) phase noise. It's easily measured with the
right equipment and processes. Phase noise plots will show it very clearly
down to 1Hz or so and below that you want to start looking at Allen
Deviation plots.
We've had this discussion (many times) so not sure why you keep bringing
up these 'conventional measurements' statements.
Have you managed to get these plots for the SAW oscillators you are using?
With / without supercap supplies would also be worth doing.

Just tried to compare A1 with A2 to see if the pattern exist about the effect of the cap, but A2 started too fast compared to A1. That IS a lot more "gross" than just dB difference for "blind" test (so I cancelled my comparison).
Before I post my listening impressions of these mods I would really like to know what Joe made of them. Describe what you hear, lets see if there is any correlation.
Once I've posted the results and comments, then that makes further subjective comments on the files invalid in the eyes of many.

Yes, its good to play the oldies sometime 😉
This was another gem from way back yonder,

Two excellent bands, both favourites of mine, managed to update all my Genesis to CD, just got to update my 12 odd Renaissance LPs. Had a quick listen to the tracks but had to do it ala FAS42 through my PC monitor as I am redoing my room and the HI-FI is in bits! no difference detected but not really top end playback.
On the supercap mod, how long are the leads used, are they the same in every mod i.e. been specified as part of the mod for consistency. The ESL and ESR as pointed out earlier is going to mean these devices are not operating at a very high frequency and in fact will be more reservoir caps than decouplers.

I took a 5 min quick listen to the DAC Mod 1 files last night.
From the sunroom, I do find differences.
For the Natalie C tracks, I found one version to sound brighter/noisier, and the other version to sound calmer, however the 'timbre' of the vocal wasn't quite right.
This listening is 90* off axis and through sliding door leading out to the sunroom, so no real depth information appraisals can be given.
Off to a home cooked sea food and Champagne hot date tonight 🙂mischiev🙂, and working Robbie Williams show tomorrow night, so no time to take a proper couch listen until Sunday night.
So, despite Mooly's recording soundcard limitations, my findings is that there is a readily audible difference.

still a very large component, for local high frequency decoupling you need a SMD device next to the pins, these will act as a reservoir capacitor.
No, not so much, though I liked the first Yes album. My tastes in Prog Rock run more to King Crimson, The Bears, Gentle Giant...
