Greetings friends! So help me out here. If I want to download a hi-res version of say Day& Age by The Killers (widely available on several sites) but the band has ever only officially released the CD. Where do these sites\/services get their copies of the original lossless masters? I'm mean, I have Blu-rays of Pink Floyd Animals and Jethro Tull Aqualung, and they sound amazing. But they were official\/remastered releases, ya know? So are these tracks really uncompressed\/taken from the studio masters? I feel like they just tweak them and call them "Hi-Res." Any input would be much appreciated.
