Yes, nice idea--to get new customers. Remind´s me to the Mp3 hype, 3D television and curved tv screen´s.
For sure there is more information in High resolution files, but this does not help if the recording is crappy. And to my ears, a lot is or could be better.
And IMO fine recording and tonemeister data is useful for unplugged live music, Jazz, Classical stuff but who need High resolution data on Metall, Rock and most of the Pop music production? To make it worse, most of the Instruments in Pop production´s are sampled, not real, at high tech level if we are lucky.
So i prefer a good redbook CD data over most of the high resolution music available that was produced on lower level equipment, and streaming is not a progress in quality!
My HiFi rig is upper level, Headphone and Loudspeaker --- and i did some serious tests with Data from several services and this is my personal conclusion/ opinion.
Even Apple might not change my mind.
I read also that Apple plan to sell 96/24 bit Data on iTunes soon.
This would be a acceptable option for me. First check if the recording is worth the upper effort and buy after. But that is just another high bitrate service.
