Thank you @andy2 for the link to the article. I am willing to learn each and every day. Peace.
Would like to read the article but ... got blocked for being an outsider, even though I have expensìve stuff!
Umm, I just went to the Upscale website, and selected guides from the menu, and can read the article WHY THE “BITS IS BITS” ARGUMENT UTTERLY MISSES THE POINT, which I assume is what this thread refers to.

“Bits are bits” happens to be the same argument many folks use to “prove” that the sound of CDs cannot be changed by CD fluids, or by color markers like the Green Pen or Purple Pen, by using holographic foils on the CD, by isolating the CD player, by reversing the digital cable (directionality), by damping the CD itself, by beveling the CD outer edge (to correct out-of-round), by demagnetizing the CD or by demagnetizing the digital cable.

“Bits are bits” is also used to “prove” that all CDs that are produced using the same digital file sound identical.
