Hi, I was searching for new dap. -Large memory (16 gb or higher. hdd will be better) -sdxc support(i heard that some sdxc 3.0 cards are compatible with regular sdhc slots. But the new 4.0 cards requires sdxc slots-- Could someone confirm it?) -Android OS But i have found nothing, as expected. So i decided to buy an smartphone and combine it with fiio e17 dac(and in the future time other dacs) Which smartphones supports e17 dac? Is there a list for android...
