I waited and waited for the onkyo to release a new app to improve UI but it seems like it is not happening. That and the fact that it is too large to take on my daily commute in the span of the short time I have bought it I only used it for less than 80 hours. . No matter how good it sound I have much better sounding DAP with the same poor UI. I dont really want another dap that I am forced to use folders to navigate, hence why I am selling it.
