i've been looking internet for months to compare. DAP under $200 with touch screen, bluetooth, all the other features, there are Sony nw-Aseries (the most expensive, lack power output, annoying cable,no streaming music). Hiby R3 (some people said it lacks treble, and one video in you tube also said that Sony nw-Aseries have better clarity and high's), and the last one FiiO M6 ( i think its the cheapest and i dont find the problem like in the other 2 devices)
other DAP under $200 other than these 3, dont have any touchscreen i guess, either using some super sensitive touch panel like Cayin N3 and FiiO X3ii, or you like school style like xDuoo dap's.
So correct me if im wrong, but compare with any other DAP withn this price range, M6 is a wonderfull package.
