Yes, you can download a low rez version, if you want a low rez version. Low rez is fine for computer speakers, headphones and boom boxes. I prefer higher quality audio media -- in order of quality (i) LP, (2) SACD, and (3) DVD. There are good pressings of CD, but it is hit or miss. And of course, there is not always a choice. But if I have a choice, I will always choose better audio.
Other people have other preferences, and that's fine.
