DACs and reproduced sound

I think that this is an interesting technical discussion, lots of information. I keep on thinking that if God came down with the perfect DAC, none of us would probably like it. The whole Analog to Digital Recording process, plus the Digital to Analog conversion, has consistently removed Harmonic Content and Decay. Some of the best DACs have tried to reproduce what little Harmonic Content there is on the CD Disk. I believe that some utilize their Analog Output Stages, to overemphasize the little Harmonic Content there is. I don't bear any grudges to the changes from the original, because the Digital Process is so largely damaging to the Harmonic Content, that any exaggeration in the opposite direction is an improvement, within reason of course. This is why, I believe that if God did provide the perfect DAC, it would be the perfect magnifying lense to all of the huge warts of the Digital Recording Medium. More accuracy only exposes less and less Harmonic Content that is inherit in the Digital Recording itself. You might have the perfect DAC, but you probably wouldn't like it!

Dear Dgarretson,
I wasn't claiming that a "perfect DAC" would be too revealing of the underlying flaws of the CD Format. Every Recording, Analog-Digital Conversion, and Playback peice of Equipment damages the original to varying degrees. They all still damage the original never the less. There are going to be some that greatly damage the original signal magnitudes greater than others. There are huge Sound differences between DACs; however, there is even a greater disparity in Sound Quality from one CD to another, that is clearly discernable even with the worse DAC. The only explanation for this huge disparity, is that the Analog/Digital Conversion does most of the damage to the Harmonic Content of the Recording. Magnifying this damage by increasing the accuracy of the DAC ten fold, might ameliorate some of the damage that the DAC causes, but won't even put a dent in the damage that the original Analog/Digital Conversion has caused. Such Damage is so severe, that the only solution might be to err in the opposite direction in the Analog Output Stage. Certainly, this means modifying the original, and not being ever more faithful to the accuracy of the severly damaged original signal. Being ever more faithful to the original signal, could even end up distorting the Music even more severe, by compounding the damage that was done during the Analog/Digital Recording Process. It may sound counter intuitive, but I believe that there is more going on in our Analog Output Stages, than just being faithful to the original signal.

" I can't recall a Reviewer ever stating that a top player made a CD sound worse than before ", does this mean that they are all perfect, or does it mean that only the perfect players were the ones that were reviewed. Your point of a 110% perfection, is suspect in itself.
I have also heard a huge improvement in each new generation of Digital playback equipment. The problem is that your best CDs sound better, while your terrible sounding CDs got even worse. This is all of the proof that I need that all of the huge advances in playback Digital/Analog Conversion still cannot turn a sows ear into a silk purse. There is inherit distortions in the Digital Recording that the best DAC in the World cannot ameliorate. The common perception, is that Jitter is the culprit that effectively vacuums up all of the Harmonic content in the Digital Recording. Henseforth, vanishing low amounts of jitter appear to be the selling point of top DACs. Harmonics are simply multiples of the cycle of the original Musical Event, usually at a lower level. If jitter isn't within the threshold of human hearing to distort the original Musical Event, why would it completely vacuum up the Harmonic Content at lower levels? The explaination is that Harmonic Content is more complex than the digital system that is trying to reproduce it. So, with all of the advances in Digital Recording and D/A Conversion playback, with vanishing low Jitter, do Digital Recordings still suffer from a vacuum of Harmonic Content? It doesn't seem to matter what digital equipment is used in the Recording or playback, Digital still suffers from a lack of Harmonic Content when compared to the best in Analog. You won't find a Digital System that sounds as good, with Harmonics, as a comparative Analog System. You might get a little closer, and a little closer, but you will never eventually get there. I fall back on the Empirical results of 30 years of development in Digital Recording, and Playback, with vanishing low Jitter, and Higher Sampling Rates, and still we haven't reached the level of Harmonic Content that a 60 year old system could easily reproduce. Perhaps Jitter is not the only problem?
