So I'm an old guy and while I like a wide range of music I can't deny I like the stuff I grew up with the best. I was looking for some classic rock DSD albums to download and try on my WM1A and there isn't a huge selection. In fact I already have most of what I could find in FLAC ripped from my CD's. This coupled with the kind of high price of DSD downloads has me hesitating. Is it worth the price to download some of my favorites that I already have, in high res audio? Will I really be able to tell the difference? I have to say that the flac files I have now sound really good to me on my WM1A / TA / Z1R system.
