Hi everyone, I recently got a FiiO DM15 R2R which sounds great. However I noticed that a faint beeping sound comes out of the reader every 5 or so seconds. I returned it because I thought maybe I got unlucky. I got a new one and i notice it again. With my headphones on it's no problem but if my music is coming out of a speaker and I'm not playing really loud music I can hear this little beep sound every few seconds.

Has anyone experienced this? I'm not sure if I should refund it or not. I love the design and sound but this issue annoys me.
