Take the whole complex signal chain, from vocal chords and guitar or piano strings, all the way through DSP, pits and valleys on the CD or binary bits, D/A, A/D, flying amplified electrons, to the cochlear hair cells and the fantastic gray jelly between our ears...
There are only a few really relevant questions:
1. Can I consistently identify a difference between a signal processed using method A vs. method B?
2. Do I prefer a signal processed using method A vs. method B?
Objectivists say you are being silly if you prefer a particular processed signal (#2) but are unable to consistently identify a difference (#1).
Subjectivists say (1) so what, I prefer it, or (2) it is way more complicated than that, or (3) this is not a quantifiable phenomena, or (4) methods for identifying differences are flawed or not applicable. They probably say a lot more.
Anyway, I haven't tried a higher resolution recording, but I want to. If I prefer it I will be happy, and probably won't worry too much about identifying differences.
Can you believe what hair cells look like?
