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.

Just read Kevin's article at the Muse site. I think it caps this discussion nicely. Check it out: http://www.museelectronics.com/download.html
Pheew! Anyway...One thing that does seem to be true is this: We all don't have engineering degrees, myself included, and that goes for the audio mag reviewers as well! If there is a "silver lining" to all this, it would be that the information learned here came from the highest sources! C'mon - direct input from Kevin Halverson at Muse, no less:-)! BTW: Thanks, Kevin. Jordan and Craig have contributed greatly to another ("Up and Oversampling") thread and have credible answers from reliable sources. Carl, you have as well on a variety of topics. I, for one, THOUGHT I HAD a solid understanding of the digital process from A-Z. I now know I have been a "victim" of the confusion set forth by digital "buzz words" in the industry - flowing out of the mouths of dealers, reviewers and corporate marketing. The point here is, at the end of the day, we have gained knowledge. This thread may very well save someone from spending $$$ on "new" equipment - or it may make them go buy it (either way)! I think everyone's motives have been sincere here and it has done the Audiogon community a great service. BTW: I'll STILL read Stereophile!
