I use the Ayon Skylla 2 DAC, which uses BB PCM1704K R2R chips from the late 90s.You need a good R2R DAC, IMO, to get that weight.
The Aries Cerat DACs use multiple AD 1865N 18 bit chips and these have the most substantial piano I have ever heard. Very realistic despite the "antique" chips.
Your Adcom and BAT both use the Burr Brown PCM63K 20 bit R2R chips. This is one of the best DAC chips ever made. I think it is not so surprising that you chose two players with the same DAC chip (probably similar receiver chip and digital filter as well...but don't know for sure). The Adcom has SS output and the BAT tube output BUT what you love about the sound is similar for both machines.
For redbook cd it is hard to do better than these DAC chips. They were very expensive to buy for the manufacturer compared to D/S chips.

Were D/S chips even available back then? Or maybe they were just hitting the market and still unfamiliar to high-end manufacturers?

Of course they were available...relatively new but available. There was probably a good decade or more of overlap before the last of the R2R chips were discontinued (some may still be made...not sure).
I once saw the prices in a digikey or Mouser catalog (can't remember anymore) where a BB PCM63K chip was $70 and a BB PCM1792 chip (a pretty good D/S chip) was like $5.
The push away from R2R had more to do I think with cost cutting than sound quality.
Are modern D/S chips better than the best R2R chips? I don't think so when it comes to sounding like more realistic. You can throw all the numbers you want at it and I won't disagree that the modern D/S DACs all measure much better. So what? Does that lead to unequivocal better sound? Not at all. Many will prefer the R2R as more natural sounding.
