Great idea but I will give you one word why it would never happen-- PIRACY. If you could upload the entire disk into the machines RAM, then it wouldn't be too hard for some criminal mind to figure out how to tap into the memory to make excellent copies of the disk. All that said, maybe they could develop some type of manner of preventing this but look how successful they have been preventing piracy to date i.e. almost not at all. It is this fear of piracy that would prevent your excellent audiophile idea from becoming a reality at least in the near term
