I really think this technology is so changing that what is said here is obsolete immediately. I have sacds in dsd on my hard drive that I can merely click on using my Ipad and have played in Itunes. Listening to sacds on a universal player is quite deficient in comparison. Soon I will have a dsd capable dac, which I long to hear. Already the sacds in dsd are superior to 192/24 HD.
Yes, all of this is consuming lots of space, but I have hot removable 2 Tb hard drives in a raid system with four drives that are upgraded when I add new files. I am soon to place one of these in my safety deposit box and monthly update it.
