wow, can so many people have such bad reading skills? its kinda hard to believe, people skim and completely miss the point. I guess its a generational thing… Fiio and others might notice that over on the portable transport/portable dap thread, almost 50% of ~35 people so far, have voted for transport only.
the iriver is what I use, but its only from necessity, with SD mod and a lipo battery upgrade battery life is excellent and it has a tethered remote, but it resamples everything, has only one crappy clock and is larger than needed. luckily I DO use it with an ESS dac, so the clocking isnt such a huge deal.
USB out would be an option, not a solution, only SOME dacs which have their own power are able to let the host know and i'm sorry but if you think implementing a USB audio codec is cheaper and easier than other types of AUDIO output, you are sorely mistaken. it would mean another clock and a more complex PCB layout due to the need for another ground layer, chip speed and faster clock edge risetimes are a major source of ripple on the power supply rails and ground. it would be cool indeed, but its not a cheaper solution. It would also mean paying licensing fees for the UAC (USB Audio Codec) driver chosen
