Your suspicions are correct, the ability of a DAC chip to decode 24/192 has nothing to do with its performance or sound quality at 16/44.
You are also correct that the primary reason why sigma-delta DAC chips have almost completely replaced multibit R-2R chips in audio applications is SD's lower chip manufacturing cost.

The reason why the R-2R approach is expensive is the critical difficulty of matching the components, without which the approach yields non-linearity and distortion. The delta-sigma approach sidesteps this problem by clever design techniques, which if done correctly yields higher performance than is possible with R-2R regardless of cost.

But it's how you define "higher performance" that matters here.
In this thread I have suggested that another poster find a Denon DCD-S10 II and have a listen. This suggestion is based upon many hours of happy listening to an audio friends system
This same person recently had a new "super" clock installed in the DCD-S10 II, and also had someone go through and upgrade all caps etc. I've heard this player twice since he got it home...the only way I can describe it is amazing!!
The same guy also owns an EMM Labs SACD/CD player that set him back quite a few bucks - it's getting no air time.
The Denon uses the PCM1702J...a lowly 20 bit DAC, but as musical as you'll find.
Is that "higher performance"?
For $1500 he could have chosen the Denon A100, which has SOTA components already plus ALS 32 processing....beats anything I've heard, like my XA5400Modrwighted player and my Levinson 360s/37 combo. It will go down as the "One" that you should have purchased, but didn't. Why? Because it didn't get reviewed and your audio snob friends said it couldn't be that good:O) Psst..it's better than good, it's phenomenal!

Possibly "as musical as you'll find" - - for people who are satisfied with redbook CD quality. Many folks here (well maybe not here here in "Digital" but over in the PC-Audio forum) have moved way beyond CD quality with very high resolution music files that would never come to life through a dated 20-bit DAC.
But if you're talking strictly CD's I suppose your comment makes some sense.
I'm referring the CD...I've given up on SACD, and at this time have no interest in using my computer for more then email.
Regarding the high res solution though, I visited a gent late last year in North Toronto to have a peek at a pair of Sonus Fabers he had for sale. He had what he described as "about as good as you can get" setup utilizing a Mac and who knows what else. I'll agree that it is different, but I'm not sure it was better.
Let's face it, after listening to both live and recorded music for well over 30 years now, and most of it Rock or Metal...well, my ears are likely not what they used to be. But I do know what hits me the right way, and I'm not convinced that digital audio is going in the right direction.
