I don't claim to have golden ears but I am a picky listener. I've been pretty satisfied with good MP3 encodings like 320kb/s though I'm not sure I'd agree they're indistinguishable.
I had an experience I mentioned elsewhere in this discussion, about hearing a difference between 24bit 96 kHz and CD-quality in a sound studio. I don't know whether the operator screwed up or what. It doesn't mean I don't think CD quality is "good enough". But that's not the same question as "non-discernable".
On the other end, I have had a few encounters with satellite radio (SiriusXM) and I cannot understand how that product exists. In each car I've encountered it, I've had a visceral reaction and wanted it turned off after a few minutes of trying to listen to it. It put me somewhere between anhedonia and dysphoria.
