That doesn't make any sense at all. I have a turntable and a CD player in the same unit, playing through the same speakers, therefore a new music player can play old media from its original source, just like I have a VCR and a DVD player coming through the same TV. The only thing is that better speakers only make things sound better (except in the case of some new music, which is actually engineered to sound bad and thus you need bad speakers to mask the imperfections in the mastering). New TVs, on the other hand, make the old media look worse because of the way it handles low-resolution video.
