Empathical YES on both counts. In an A/D/A conversion the quality of what comes out is (perfectly?) correlated with what goes in. If I prefer DSD source direct playback without A/D/A conversion downstream, I would still prefer it with A/D/A conversion.

When I did analog into the Meridian G68 (I was calibrating a system at the time) the output was still in a non SPDIF format, even if it wasn't unencrypted. My DAC picked up the sample rate as 88.2 but that was as far as it went....
That is because it was upsampling. I am told by someone I trust that, if you set it to not upsample, you can get S/PDIF out. Unfortunately, it is also fixed level.
In an A/D/A conversion the quality of what comes out is limited by the weakest element and sums the distortions of each conversion.
IMHO, the main issue is no user control over the target curve. It's a deal killer for me. Dirac Live has target curve editing (much like Audyssey Pro and Trinnov's own systems), and according to Carl Huff, Dirac is sprucing up the U/I, so the RS-20i and Carl's own eminent standalone EQs ought to be more usable by mere mortals. But we have to wait and see.
Right. The supplied target was clearly anemic in the bass and Sherwood provided me with additional targets but installation and swapping were kinda cludgy and not tweakable.
The target curve that was "anemic in the bass" are you referring to EQ? Volume? Both, ect.? On these additional targets, did you try them? If so, what was the difference?
I agree that manually creating target curves over VNC links with an expert on the other end of the line is not a very scaleable model commercially. However, a menu of various target curves that you can swap in an out in near real time would achieve 95% of what you can achieve with manually created curves. All you need is the on board processing power to do this. The Sherwood probably did not have this, but a full blown Trinnov ST2 does. A target curve menu would also allow you to pick different curves for different styles of music or say listening volumes. All you need is lots of onboard CPU cycles.

They offered curves with different amounts of bass. None of which worked for my sensibilities. My target in the bass looks more like Harman's Synthesis or Holman's -30 dB curve from his "Loudness Compensation: Use and Abuse." Figure 3 as attached.
The black line above is the Synthesis, the red line is me fooling around.

Any concern with your red curve overdriving the subs?
The upper end roll-off probably matches my old ears, sob...

It not only overdrove the subs at higher levels, but exposed low frequency junk on movies and music recordings that seemed unintended at best, so I toned it down. The Harman curve is much more practical.
I visited RUR's system over the weekend and subjected him to that curve, using the 1/3d octave EQs in the ST-2. Naturally I liked it, but the jury is still out from Ken's perspective. It's something one has to live with for a while after running "flat".
Roger, the first picture (graph) from your above post (#111) is not showing.

"Subjected" sounds unduly harsh, Roger! Personally, I thought that Morgan Page number was pretty damned awe inspiring.

C'mon, let that Seaton stretch its legs.[For other readers -- Ken has a sofa located behind the MLP. There is additional bass excitation provided free of charge.]
No. And probably because I was dismissed from AVS Forum two years ago (no access to any attachments).
No big deal, life ain't always fair all the way ...

Thank you for trying Roger.
