Data and signal: are we progressing?

Are bits still just bits? Actually, notable part of improvements achieved in the digital audio in last two decades happened due to designing for higher signal integrity criteria. So not that much for instance in the area of converter chips, which were during this time developed mostly to lower production costs. As a result, even if Philips D/A chips from 80’s are in many areas still unsurpassed, today it would be unimaginable for any serious design to repeat the layout or clocking schemes as they were done in Philips CD players from 80’s (or in the majority of players from that time, for that matter).
