Just add some pink noise (ok, we can argue about the best noise shaping) - the more experience the listener has with live music - the more fine details the listener's brain will create from the noise. And yes, this just a joke, but ... just partially. I'm curious, how much this phenomenon (recognizing false patterns in noise) is adding to "best sounding DAC" vs "best measuring DAC" discrepancy. And amps also. I got this idea from @kixx post in "USB decrap..." about "ipurifier"
