I know. But that's not what you said, you said it doesn't add anything, my point was that of course it does add something, and I think you knew that already when you said it, I was just getting pedantic about your phrasing. I think your point was that it can't replace what was lost at the point of digitization, with which I agree, but I think you missed my point. ...amongst other things, one of which I consider more important when discussing DACs, and that is the quality of the interpolation/upsampling algorithm. (The DACs don't affect the sampling precision if you're stuck with CD's.) Stressed for accuracy -- that is, like, your opinion, man. As has already been pointed out, we aren't as concerned with '...pretty numbers for the spec sheet...', either, but the pleasure derived from the resultant listening experience. I, personally, believe that electronics design is a game of trading compromises in one area for compromises in another -- frequency response for phase accuracy, for example -- and that no area should be ignored in terms of possible improvements. What's wrong with playing with the signal in the digital realm if you can? Sure if it's at the expense of the analogue stage, then...bad, but it doesn't necessarily have to be, so why not? I mean, you have to be careful that you don't fuck it up worse, but you always have to do that at every stage anyways, it's not a guarantee that you're going to fuck things up just because you do something to the signal. It's called experimentation, the very essence of engineering.
