As I wrote, the links are proposals among others for attempting to give simple definition to both "technologies" : OVER- & UP- sampling.
Simaudio staff, for instance, has also another point of view : http://www.simaudio.com/pdf/Upsampling.pdf
Interpolating the sample data is a trick or tool among others, to get back to analog domain, as you mentioned.
But it's also a mistake to underrate digital signal processing, these involved technics aren't specific to our hobby : listening to music ...
I do own a dCS972/954 combo, and it works great, amha.
I've also listened for two weeks to a non-over/up sampling product : the Zanden DAC.
And, well, in a perfect world, I would like to be able to afford to buy one ;-)
The ARC CD3 is also a great sounding machine !
Happy listening, Emile
