Yes, way, way past time for this BS about stairsteps to die. It is so far off track it is not even wrong.
Watch this video.

Using quality analog sources, and quality analog monitoring after an AD/DA stage you will see the above illustration is nothing more than someone's misguided imagination.
If you don't believe him, you can get an O-scope and check it for yourself. Having done so, I can save you the trouble and say don't bother, it will show just what the video shows. But you don't believe any of us? Fine, no problemo. Just get yourself a good analog oscope, quite cheap these days and try it for yourself. Until you confirm the stairsteps, stop perpetuating this god awful, incorrect, BS. You should feel very ashamed. Very ashamed. At a bare minimum you should feel badly for having been taken in. Don't spew this garbage out into the world.
Yes, thank you. That's the video I had in mind. Everyone should watch it. I did, and it was good to have my preconceptions corrected.
That doesn't mean that digital is as good as, or even better than, analog. In theory it should be, but my ears tell me that in practice it is (not yet) so. Yet as Amir says, one should not use the wrong technical arguments to 'prove that digital is inferior', and one should also not dismiss the technical arguments why analog is technically quite flawed and the measurements that prove that it is so -- even though to my ears on the best equipment currently it still leads to superior results, for whatever reason; and no, you cannot explain away superior timbral detail as 'coloration'.
