Upsampling DACS: Take the Pepsi Challenge

I guess Jeff Kalt is a better man than me. That's why I bought his CD player over a year ago. I guess since there's no difference in upsampling and oversampling, then there'd be no difference between my CD50, and the new CD55. I'm ok with that, too. Why aren't you, you little squirrely thing, you?

Again I advise reading August HFNRR, which describes the two techniques, although they can acheive the same end result, the "process" is different......read and find out the differences, they claim they can hear the difference

Check out the MSB site's description of their new Platinum DAC where they take a stab at describing the differences. BTW this is an excellent unit. I replaced by Theta Pro Gen Va upraded to 96k with the MSB Platinum unit. I directly compared the Perpetual Technologies upsampler with both DACs and thought the result was inferior. I actually had the dCs units in my system on a borrowed basis earlier this year. In my opinion (but from my memory) while they gave better sound the Platinum covers more than half the distance from the Theta to the dCs. The Platinum's balanced outputs are able to drive my power amp directly from the DAC without an intermediate analog buffer stage. I think good comparison to heat the effects of the digital processing, if you have an excellent analog rig, is to compare the RCA Reiner recordings of Bartok's Concerto for Orchestra and Music for Strings Percussion and Celesta on the Classics Records vinyl to the most recent remaster on CD. These recordings are some of the most realistic recordings of a symphony orchestra ever made. The difference with upsampling jumps out. (The vinyl is still better but not so much that really bothers me)

Thanks Megasam, the HFNRR article was most interesting. Thanks Greysquirrel for going to a source with cred. I agree with Carl's first 8/2 posting -- yes, you are not the real expert here. BTW, you really do owe Deborah1 an apology. Your 8/1 comments are way out of line, IMHO.

Thanks Onhwy61, but no apolpgy necessary from Carl. His remarks were so outrageous that I just had to laugh. I guess I did get SOME retribution: it seems us "less curious" types are not as easily swayed by what in the end is MARKETING HYPE! (see my post on 7/31) And this from Carl's FAVORITE digital guy, Jeff Kalt @ Resolution Audio! BTW Carl, kudos to you for sticking to your guns: I've seen on another thread ("What is Resolution Audio") that you even DISAGREE with MR. KALT on this topic of upsampling! Seriously though, we must all remember one thing, and this just might come to aid Carl's position in this matter (is that ironic or what)....Just because we have no rational explaination for how or why something affects sound reproduction, that does not mean it has no real effect; especially if "skilled" listeners hear a difference. Our brains seem to be able to perceive HUGE differences in sound quality where none exist on the test bench or in the designers lab. So maybe upsampling falls into this catagory; it can't be justified from a technical point of view, but it still somehow improves our perception of the quality of reproduced sound. But I do think Jeff Kalt made a valid point in his e-mail to Greysquirrel: different is not always better, or more accurate. And thanks Greysquirrel: this has been one of the most heated thread topics I can remember!
