Hi Carl; I certainly hope you don't think (that I think) that your opinions are irrational on this subject-- we're all doing our best to understand it and its significance. You actually understand many of the details of this complex engineering subject, whereas I never will. I respect you, your views, and enjoy your posts. As to this subject; as a result of responses from Jeff Kalt (by Greysquirrel), Theta Digital, and Madrigal Audio, I've concluded that I was totally wrong about over-sampling vs upsampling-- these industry leaders apparently consider them the same thing, and I for one am glad to finally know this. My ego wasn't bruised at all when I found that my perceptions were wrong. As to differences in sound quality of digital components, I'll say again that Theta Digital is probably right when they say "implementation techniques vary". And that also explains why dCS gear may be so good (and so expensive) while others are building "up-sampling" components for a few hundred dollars. I'm looking forward to seeing Madrigal's position paper. Cheers. Craig.
Upsampling DACS: Take the Pepsi Challenge
HAs anyone used 2 of the following 3 relatively inexpensive upsampling DACs: Perpetual technologies, Bel Canto, MSB Link 3 with upsampling upgrade?? I am trying to sort out the details of the new technologies. The Perp Tech can "interpolate", while the others do not. I am under the impression that the "24 bit" part of this new technology has to do with s/n ratios aroung 140 db, which is great, but a little useless considering the other equipment in the system. The sampling freq is the part that has me all aflutter, because it seems to be getting closer to analog quality "infinite sampling" if you will... What do you think? Has anyone compared these dacs?? Thanks, gang.
