Except that in every objective test the iOS devices show a near 0 THD, nearly flat recency response and a nearly perfect dynamic range. While perhaps "technically better" is the case with the Pono, the simple, physical, physiological and demonstrable fact that 100% of humans can not hear the differences you are taking about in any testing case means the different and "bitterness" is simply snake oil. Right up there with Monster 'monitor interconnects' and speaker isolation stands.
The question to ask is - if what you say is true, then why do studios record in these higher bitrate and higher bit depth formats? If they record in analog, they will again record the music in a high bandwidth medium like reel tape.
Then the second question is - if studios record in these high bandwidth formats, why can we not listen to music in the same format as well?
A decade ago, record companies would compress the music because storage and bandwidth was expensive.
However, with current tech and internet speeds, that should not be an excuse.
Heck, video content providers are able to stream high quality videos that consume a magnitude higher levels of bandwidth and storage space. There is absolutely no excuse why audio fidelity of source music should be needlessly compressed or butchered nowadays. And I really don't care if it is needless data. All I am asking is to give me the same file that the studio uses.
