For this to really go mainstream, it does seem it really has to be more idiot proof, more standardized, and the availability of a large library of fast and easy hi-rez downloads. I see the appeal, and perhaps the inevitability of this, but the more I see where we are at this point, the less I feel ready for this kind of change. It really has to be almost as easy as buying a CD, putting it a CD player, and hitting play. The ideal would seem to be a universal music library stored externally (the cloud) and accessible for a monthly fee via a wireless 8G connection to a device in the home that receives and streams hi-rez digital data into a DAC (or built into the DAC box) - a variation on Netflix I suppose.
