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.

Carl - look for the thread about vinyl and live music. A lot of recording-types and musicians in on that one. There is a great explanation by a recording engineer or two about high reequency roll off in the vinyl recording process. Maybe something to do with RIAA? Anyway, read through the thirty or so posts and try to learn something for a change instead of letting your not insignificant bruised ego stand in the way of reaching an understanding of how the brain processes sound and how the process of recording sound onto vinyl is compromised. As to your juvenile comments regarding hearing - only true way to accurately compare or measure hearing is in a total anechoic chamber using standardized methods. Best place I know of is at an Eye and Ear Hospital. Yours better that mine? Doubt it. I don't really care. What's it going to be next? Dualing triodes at 10 paces? Grow up. Time to go play with my stereo.

I am not Carl, and I do not disagree with your comments about LP. having a high frequency roll off. Perhaps it is the RIAA, or perhaps a flaw in the original design of the LP format (it is quite old). However, the roll off in the extreme highs is less of a problem to my ear than the brick wall filter in digital, and the additional problems with the digital format's phase response. There is no perfect format for the ultimate in home reproduction right now, and in the years to follow, perhaps digital will finally accomplish what was originally promised it would do (20 years ago). However, I have been listening to recorded music for all of those 20 years, and I pride myself in extracting all the performance from my system that can be had. And, as you said yourself, LP. is the superior format right now, so until things change, I am happy to enjoy my rather large collection of music and know that considering the state of things, I cannot do better.
