Philips in issuing their Crown chipset, the venerable 1541, with only 16 bit 44.1 sampling, claimed why ask for more when all you need is a "perfect" DAC chip for the information at hand?WHile very popular, that did not stop the tidal wave of higher bit rate sets which entered the market, claiming better high frequency filtering because of the higher bit rate.
In essence, DAC's become part of the computer race. Higher numbers as being seen as better. I do not believe the algebraic manipulation of these numbers has improved much though, nor the addressing of certain particular issues as it pertains to music and digital

there's no question in my mind that modern cdp's and DACs are far far superior in sonics to the first wave of "perfect sound forever" products, all of which were 16/44. So, something got better. Whether there is continuous linear improvement over time up to the present is quite another matter, however, IMO.
a large part of the issue is in mastering. In analog, its ok to use low level recordings. Not true in digital. You need the bits to get detail and the number of bits is also correlated to volume , unfortunately.
Over the years I notice my discs are getting louder and louder. And they do sound better.
Also, although it receives very little mention, the analog sections are greatly improving. employing judicious filtering to roll off the RFI edginess, although I believe the pendulum has swung a bit too far in that direction.
Apparently some of the sonic improvement has to do with the appreciation of the jitter phenomenon and how to fix it, or so we are led to believe (or beleive).
What was interesting is, as an former HK dealer. I had access to service manuals . In the early 1990's their top line models ( 7500, 7600) had jitter figures in the very low teens ( 12-14), much lower than any separate stand alone DAC and transport. Makes you wonder, and I used all the tricks: reclockers, upwards dithering, trick cables and such.
