[sdiy] Digital accumulator VCO core?

No.  Because the 16 (sic) bit Burr-Brown DACs in every CD player were crap, the ADCs in the digitization studio weren't much better, and good compressors were rare so a lot of CDs were recorded with so much headroom lots of the time the output was down towards the noise floor.  That's why many CDs were remastered in the 1990s.  Also remember the Phil Collins debacle where the CD stopped playing half way through because a particular bit sequence matched the end of track flag.  Everybody was saying "why the f*** didn't they just wait until 20 bits was available".  Quite a few artistes refused to do CDs until the quality improved when ADC dithering and 1 bit DACs came along.

Of course nowadays with MP3, a whole generation has found about 12 bits is more than enough for their hyper-compressed noise, but hey-ho.

One would assume because of the programme material, rather than any flaws in the recording and reproduction process.
