24/96 upsampling vs. 24/192 upsampling vs. no upsampling?

I am interested in digital upsampling; however, I have never heard a DAC or CDP that upsamples. Can anyone tell me their thoughts on 24/92 upsampling vs. 24/192 upsampling vs. no upsampling at all (sonically)? Is upsampling that much better? How is it different from the 2x, 4x, and 8x sampling players of the past? Currently I use a Camelot Uther 20 bit DAC in my system, and a 24/192 upsampling upgrade will soon be offered by Camelot in the near future. I am wondering if it is worth it to upgrade. I am also interested in the Perpetual Technology digital gear. Thank you for any insight into these questions.

Upsampling and oversampling are essentially the same thing. Try a search under upsampling. Craig

Upsampling is converting 16 bit data to 20-24 bit data so a different kind of filtering can be used when the data is converted from a digital signal into an analog signal. The word on the street is that typical digital sounds so "unrefined" do to the radical nature of the brickwall filter used to block all frequencies exceeding 20K or so. 24 bit, high frequency sampling uses "kinder, gentler" filtering which imparts greater "finesse" to the music. After all, isn't "finesse" the ultimate goal of audio? I'm looking forward to the day when I'm sitting in my easy chair and thinking: "I just can't imagine this any better".

Question: Does an old 16bit CD really have all the information on it (beyond 16bit) so you can change it to 24bit?? This has always confused me about unsampling?
