Upsampling DACS: Take the Pepsi Challenge

And Jordan, how many CD players or DACs have YOU designed? I want to know, because it seems to me that you are pretending that you have. How about letting those who design them speak for themselves? Also, onon of you have answered how your systems perform on my little test. I submit that you are afraid to perform it.

....very afraid....

Regarding "taking the Pepsi Challenge", I logged on to the Pepsi web site, and cannot find where they actually market a Upsampling DAC of any kind. Thinking Gthirteen confused Pepsi with Coca Cola, I visited Coke's site too....still no DAC's. Are you guys sure that these fine soft drink companies are into digital, or perhaps their "fizz" is all "0's" and no "1's".

As soon as the author gives me permission, I will post a note on this thread and will likely also build a link from our web site. Kevin Halverson

Carl, I did let "those who design them speak for themselves" by seeking out an answer on this topic from one of the leaders in digital design and then posting Jeff Kalt's e-mail reply here. Did you search for answers OR did you already know it all?!! I humbly entered this thread looking for answers to my questions regarding upsampling/oversampling. You, however, replied with your usual collection of technical terms (organized in nonsensical ways) AND got hostile to boot! Carl, nobody likes a hostile blowhard. From my limited understanding of how a digital processor works, I suspected that upsampling was the same, or nearly the same, as oversampling. After seriously considering your nonsense, I asked Jeff Kalt for an answer. I chose to ask Resolution Audio for two reasons: 1.) Resolution Audio now markets an "Upsampling" processor. 2.) I could kick myself for it now, but I actually thought that MAYBE you knew what you were talking about and just couldn't express it in a way I understood. Since you spoke so highly of Jeff Kalt's talents as a digital designer, I thought, perhaps, he could express what you could not. As we all know now, you didn't have a clue what you were talking about and upsampling and oversampling are the same thing! Oh, I performed your test. Heard a little golf ball in the top octaves and about a 2 footer in the upper bass. I don't know, I prefer listening to music (Miles Davis sounds good today), but to each his own. Jordan
