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.

dCS, the British company that made the first upsampler product, readily admits that there is no known reason why upsampling should sound any better than oversampling. The processes are fundamentally the same. Since many well-trained listeners report that upsampled data sounds more natural and realistic than oversampled equivalents, then I think it is reasonable for listeners and manufacturers to be somewhat confused.

It's interesting, the emotional truth at the core of music has nothing to do with the quality of the sound. Maybe that's why alot of musicians don't have audiophile quality systems. The music really is only in your head. Deaf people have composed symphonies and I bet they "hear" it better than most people.

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.

Regarding the enjoyment of recorded music, what difference does it make whether the equipment upsamples, resamples, oversamples or nosamples (Sakura and Auido Note). Stop obsessing over the internal workings of the complex internal workings of our electronics. Great sounding equipment is being made using a wide variety of designs. Sit in the sweet spot and enjoy the music.
