quick reader? actually understood all the references, terminology, math in the paper?  - there's a lot the willing learner could find with keywords in my posts that could lead to good references
 
as I said few are interested in adversarial debate as a teaching tool for engineering science and technology basics

I'll just go with the idea that m3_ created at least one of those new accounts to talk to himself.

  I find Arun's argumentation technique quite ingenious.
 
"You don't convince me, therefore I'm right"
"I'm right, therefore you don't convince me"
 
You can't lose! Genius!

Thank you; however, that's not what I'm doing. My technique is simply to propose a theory that can't be disproven. That is the definition of scientific truth.

Does anyone have measurements of NOS Non-oversampling DACs. So many claims on that they are "smoother and less digital" sounding, It might be due to the sharper AA LPF cutting off the treble earlier than a oversampling modern DAC with a slow roll off LPF, most likely not places as low as the NOS DAC either.

Most NOS DACs don't have an AAF (strictly speaking its an AIF) at all or only a 1st order one. Whereas all oversampling S-D DACs do, in the digital domain at the least.
 
I have a hypothesis which I'm testing, that's that NOS DACs sound more analogue-like due to lower noise modulation than S-D types. When I added a sharp AIF to my NOS DAC, the noisefloor (subjectively) dropped considerably, resulting in an almost holographic soundstage. This sold me on steep AIFs but its an on-going experiment to answer the question 'how steep should they be?'.
