Re: Exactly right. Besides we're talking about audibilty...

*** So we again come back to my original premise: high-rate PCM is more elegant than DSD ***

I'm not sure what you mean by "elegance" but in the case of ultrasonic noise it's a completely moot point since as I've pointed out real life PCM recordings have just as much ultrasonic noise as DSD so I don't know what you mean when you say noise shaping is more pervasive in DSD.

Using a different criteria, one can easily argue that DSD is more "elegant" than PCM. In fact, I think Sony and Phillips *are* advancing such arguments. But their arguments are equally moot because many SA-CDs are mastered from PCM recordings.

I would say - forget about the elegance and just enjoy the music!


*** if the original CD patent had specified 44.1/20 instead of 44.1/16 ***

Be thankful they did not use 14-bits as originally proposed. It's easy to moan and whinge in hindsight but you must remember at the time it was impossible even to achieve 14 bit linearity, much less 16 or 20. The only reason we can get 20-bit accuracy these days is due to delta sigma (which DSD is based on, so you are accusing something for not being elegant when it is in fact the technology that broke the linearity barrier!)

*** I'm beginning to think anything above 48/24 may be overkill ***

On my soundcard, 44.1/24 generates the "best" results, as you can see from the attached link
