Where are the spurs coming from in the analog (analogue) implementation? Noise, clock, power, ???
Funny enough my analogue pot seem quitest when on full volume . You can hear a reduction Of hiss at the tweeter. With ear right up to it nothing audible at MLP.
Well implemented digital attenuation to me would be preferable. On my to-do list.

At -140dB it could as well be a Super Nova at the far end of our galaxy.
It would be obvious if you'll plot emotion. The digital won't show any.Sorry should have used this internally. Its like veils are removed from the sound, you can hear into the depths of blackness. It makes emotion pour from the speakers

So what kinds of tests would you propose?B is digital volume and this realistically proves little imo.
Fortunately my current job does not need such huge dynamic range. However, most of my career focused on systems ultimately achieving SFDR from 120 to 180 dB or so, thus I am always curious when I see discrete spurs like that. Do I think it matters? No, just curious as to the source. Don't appear to directly correlate to IMD or image folding but I did not try to figure out exactly where they lie.
A is digital and B is analogue.

No no no...
The Shoutometer lists -140db someplace between someone shouting at you from 1 meter from a little closer than Chicago to Perth.
Light years start at -318dB, other side of the galaxy is about -400dB, on my personal extended version (-520dB to the edge of the visible universe)
I wouldn't, I would put a volume control in a device when warranted.So what kinds of tests would you propose?
People do recover from laughter.This is just a excise in curiosity, no claim here it would prove definitive in fact the opposite has been expressed from the start.
And it seems you guessed wrong, don't worry you will recover.
