As much as I hate the R10, I have to admit that the sound quality of the R10 is better than AK100II. The R10 has a 3D-like wide soundstage that never ceased to impress me. The R10 freezes ever hour until it refuses to work. The sound quality is incredible, but pointless if the device doesn't even work or stops working twenty times a day. Having an R10 is like having Nicola Peltz as your girlfriend and only get laid 5 seconds every 4 months. Eventually, you'll give up.
Is it that bad?
