I'm clueless on this latest format. 1) Is this the future which will replace physical media? 2)Should I have dedicated "hardware" that downloads/stores/plays and indexs my hi -rez music files for scrolling and locating? 3)Is there different quality when it comes to the hardware that's needed for this? 4) How do I hook this up to my existing system? Preamp/Amp DVD/CD hardware etc 5) Is there instructions on how to do this? Will this also replace Blu-ray video discs?
