To answer Mike's question, I was using an old Aragon D2A heavily modified by a friend of mine. He added larger, higher quality caps, sorbothane everywhere, a huge power supply designed by Walt Jung, and probably other things I don't know about. For a transport I was (and am) using the Radio Shack 3400 portable CD that was all the buzz a few years back. Another friend built a power supply for it. I would like to get a "real" transport, but have found it more difficult than I thought to find something that will better the Radio Shack. Any suggestions? I tried the Rega Planet in my system figuring it would be better either as a stand alone player or as a transport. No dice. I have also heard the Rega Jupiter/Io combo at the store. The Audio Note is in a different league from any of these. A better comparison is to a good turntable. I have not heard any of the new upsampling DACs. I was considering the Bel Canto DAC 1 but opted for the Audio Note. Here is a quote from an email correspondence I had with Peter Qvortrup, for what it's worth. (He seems like a pretty straightforward guy. He answered my email within an hour of my sending it.):"Oversampling or upsampling, it is still signal manipulation and in our opinion undesirable, as the experience with the DAC5 clearly demonstrates, I have a sample of the latest DCS with upsampler two and it struggles
sonically (in my personal opinion, with which everyone will not necessarily agree) even against the cheaper version with 1x oversampling that we make.I believe that it can be easily demonstrated that any attempts to manipulate the time continuum in which a music signal lives is doomed to failure, feedback in amplifiers or over/upsampling in the digital domain, all damage the integrity of the signal and given a sufficiently good application without these, that is easily demonstrated."
My understanding of upsampling is that it is interpolating data in order to fill in information that is missing from 44/16 digital. My ,and others, experience with the Audio Note DAC would seem to indicate that the information is there, but is being obscured by the oversampling and digital filter.
