Where is the music lover going to invest, in order to enjoy music of tomorrow? I love my Spotify and Pandora account but would "love me some HD streamin' Tunes"
DSD will NEVER be more than a niche format. It has a vinyl type following because of it so called "analog" sound. DSD only has a dynamic range of 6dB supplemented by nose shaping from oversampling to about 120dB. DSD suffers many problems and by far the biggest is you can't use DSP on DSD. So DSD must be converted to LPCM to manipulate. Engineers like plan "old" common 144dB 96/24 LPCM that is compatible with ALL equipment and can be arranged and mastered in unlimited ways any where anyhow. DSD requires conversion to DXD and specialized (and limited) equipment to mix and Master.
DSD was used rarely a decade ago to make a few (mostly classical and some jazz) original recordings. I don't believe any mainstream recording studios are using DSD recorders. I would say that LPCM is probably >98% of all new recordings with analog being most of the rest (just a wild guess).
Having said all this I do having collection of SA-CD's that I love. I also like the format over the more complex to navigate DVD-A.
Sony was just trying to make something different for differences sake to compete with DVD-A and it was not well thought out.
As far as HD streaming goes it will be LPCM (if Apple ALAC or FLAC from others) and not a DSD transcode (if and when it comes). The studios are extremely reluctant to offer their catalogs in a Master quality format.
EDIT: I have iTunes Radio (Mavericks beta) and I have measured some of the files coming in at 10MB to 20MB per song. So it looks like it is at least a minimum of 256Kbps AAC and maybe even higher.Edited by William - 9/16/13 at 3:09pm
