Apple may offer higher-than-16/44 and/or lossless music downloads at some point, but it would be neither a scam nor an indicator that they believe in audiophile pseudoscience — it would simply be a response to strong demand from a very profitable market. And as long as Apple’s not serving their demands, they risk losing them to competing ecosystems.
Agreed. Also, If people care about the quality of their music, they should also invest in quality headphones. I use Ear Monitors from Future Sonics.
