What the heck is Resolution Audio

My experiences totally bear out what deborah1 has stated: the BEST digital playback I've heard is the 47 labs combo. It's the simplest, it has no filters, oversampling, or anything. It's a 'simple' 16/44 redbook player, yet it sounds like . . . music. It's very musical. The cd55, on the other hand, does employ 'up' sampling, and also sounds very good. Technically, it's very different (that collage education coming into play here) from the 47labs digital stuff. All one has to do is open a road & track magazine, and look at one of their tests comparing cars; there are many different ways to get from point a to point b (and rather quickly).

I just got a 2nd email from Todd Sutherland at Madrigal Audio with an attachment of their position paper on the subject of up-sampling and over-sampling. It's 3 pages long so I won't post it here, but Madrigal says it will be on their web site within a week or so. It's written basically in laymans (and womens) terms, so it's understandable, but still there is enough RED MEAT in it that I think it would be of interest to technical types also. Here's one quote from the paper: "All current Mark Levinson digital to analog converters 'upconvert' the digital signal to either 352.8 or 384 kHz, depending on the nature of the incoming signal. Why would you want us to lower our standards to only 96kHz or 192 kHz?" That question is rhetorical of course and they go on to discuss it. Jordan, I've had to eat some crow on this issue myself, but I'm happy to do it for the sake of the truth though-- crow is best eaten with a touch of salt. Carl, have you ever tasted crow? It's actually not bad. Deborah1-- I think you'd get as much out of the Madrigal position paper as I did. They're at www.madrigalaudio.com (or maybe it's just madrigal.com?? As to sound differences among different DACs/CD players, it's explained by differences is IMPLEMENTATION of digital technology re: Madrigal Audio and Theta Digital. Cheers. Craig

Jordan, why is it that if knowledge is all you seek, that you are so interested in whether or not I might be wrong about something? Am I that important to you? If I did have further communication with Jeff Kalt, or anyone else, would it matter what they said? I submit that it would not. Your goal is to convince everyone that I am "dumb", and that seems childish to me. I will always be open minded about audio, and the needs of others who want to get petty and personal have no place here. Per my previous agreement with the Audiogon staff, I certainly will not get personal on this, or any other subject.

Carl, that was very polite and well put. Chow, Deborah1.
