Can You Recommend a Good High Res Digital Audio Player?

I have been considering purchasing a FiiO X7 digital audio player so that I could play DSD, FLAC and ALAC files. As much as my primary consideration is improving my sound resolution from my iPod Classic, I am also hoping to find a device that is easy to manipulate and transfer music files. The X7 uses a file system that is a bit clunky. You essentially navigate a file system, with folders and files. I've heard that this is common for Android based Operating Systems. To make operation more difficult, the support info is in Chinese. Can you recommend an audio player that can play hi res files with a fairly easy to use OS?
