Quote:The E7 DAC certainly seems to be the limiting factor in the E7/E9 combo... I'd be willing to spend significantly more for a better DAC section if it meant that the X3 would serve as a much better source/DAC for the E9.
Actually the WM8740 is quite capable. It is still one of Wolfson best DAC chip. It is just the way it has to be implemented on E7 that limited the function (i.e. PCM270x to handle the USB stream since WM8740 can't do USB directly). X3 won't have that problem since it doesn't need to function as an USB DAC, Of course there is still the limitation of parts quality - FiiO simply can't afford to put in the best possible audiophile parts into the DAC (or any section of X3) since they don't intend to charge you a big price tag over it.
Of course. I didn't/don't know the specifics of how the 8740 is implemented in the E7 and X3 - I know that the DAC chip is only one part of the equation, hence I called for a better "DAC section" as a whole. I look forward to hearing the X3's performance.
So is the PCM270x used just to convert the USB packet stream to the normal PCM format in the E7, and its DAC capabilities are bypassed? (Please excuse any imprecise/incorrect terms, as I'm a mechanical engineer, not an electrical one...)
