Where would the differences between the players originate? Each of these players sends the exact same information (presuming that you are being consistent with either lossless or lossy) to your DAC or headphone out. Your only difference will be UI. If you are hearing differences, its possible that you may need to spend some time ensuring your musics digital signal in your computer is not being interfered with from external programs on its venture to its conversion into analog, not related to the player itself. Someone correct me if I'm wrong, but I don't see how there could possibly be a difference between players so long as the source is of the same quality and bit perfect to the conversion.
