Oh no ... please do not regurgitate all that nonsense again.
You sound like aCalexico errm.. broken record.
For 'some technical reason' reconstruction filters are essential for OS and NOS DACs.
Leaving them out at the playback end (a 'filter' is always present at the encoding process anyway) is well .... wrong in may ways.
The ASR audio designers that communicate here do not agree with the local audio designers you communicate with.
NOS R2R is fine ... filterless NOS DAC is not, unless you upsample the 44.1 content 4 or 8 times (properly) and then reproduce it with a NOS filterless DAC.
This I do agree with... someone preferring a sound signature.

The best part with R2R is that it'snot that expensiveto make a DIY filterless NOS R2R and then experiment. Finished boards are available with more than one option. One might make a blind test on his own, then decide whether he preferred such DAC or some sigma-delta with those perfect measurements.
