Best to if your up to it compare the two with their data sheets.
Hi George. I'll leave the technical dissection to you if you don't mind. I have looked at the AD5791 previously, but can't say I completely understand it. By all means, let me know how the two DAC chips compare. Besides, isn't it you who states that the chip itself is only a small percentage of the overall sound. I'm led to believe the implementation of the chip and rest of the analog circuit is paramount.
