Concerning the phase shift between channels on a CD player that uses only one DAC: Many people have said that there really is no problem because the time delay could be corrected by moving the lagging speaker about 1/3 inch closer to you. This explanation satisfied me completely, but then I think I read somewhere the other day that the amount of phase shift between the CD channels was frequency dependent. I believe that the article said that higher frequencies would get more delay than lower ones. I don't see why this would be so. Also, I can't find the article (I'm still looking though). Does anyone have comments on this? Has anyone compared two CD players, one with two DACs and the other with only one? If so, can you comment on any audible differences that you would attribute to the number of DACs used. Bruce Kinmonth ...decvax!decwrl!rhea!null!kinmonth

Of course, that multiplexed device between your ears is perfectly capable of handling those delays/phase shifts. It's one of the things that makes human hearing so useful. -Ron

I believe that there are audible differences between CD players, and that the 2 DAC system is better on paper if not audibly. Since there are 2 DAC players available as inexpensively as those that do not have 2 DACs why not go for what ever subtle benefit that 2 DACs might produce.
