Hi all. I have a Marantz CD63SE player that I used to play CDs on it twenty years ago. After moving to a new city I left my system in their boxes for many years untouched, practically left the hobby. Just beginning last year I felt the itch to listen to my stuff again, and found the Marantz's mechanism stuck (well after all those years), for a temporary solution I just plug in my (then) newly-bought Fiio X3 digital player into my amp and play some flac and ape files, and, the result was good at least to my ears. I have bought Fiio X5iii after losing the X3 and have been using it ever since. My question to all here is: "Would digital sources like flac and DSD sound as good as on CDs, or better?" I know some "audiophiles" scoff at the idea of using any source other than CDs and vinyls. But I wonder, if CDs and flac and DSD are all carrying nothing but streams of 1s and 0s, why would flacs and DSDs be inferior to CDs? In fact, CDs is not a purely digital medium as it needs a mechanical spinning device to read it, thereby bringing in jitter and other unwanted errors. To my limited knowledge, wouldn't DAPs playing lossless tracks be more accurate than playing CDs? Since I don't have a functional CD player to do an AB test with my DAP, I'd like to hear from people who have done it and illuminate me on this matter. In the future, I plan to buy a good DAC and feed it with my PC or DAP playing high res material. Would this setup totally eliminate the role of CD players in the future?
