Can one access those measurements somewhere, to see the difference all that wizardry makes, with line level signals at least?
I have a really hard time digesting all the hyperbole and confidence in posts about audibly improved sound, especially when considering what can be measured acoustically after the amp-speaker-room chain, no matter how much money one throws at it!
EDIT:
I’d also love to see your reference system’s acoustic response in the frequency and time domains - you can see mine here and here.
