Got a pair of AE A5+ speakers last week, and have noticed that the left (powered) speaker sometimes cuts out, but not completely. it sounds like the tweeter stops or something, but the usually will kick back in. Its really annoying. And to my knowledge, there is no rhyme or reason for it happening.
I have a macbook pro with a Fiio e7 Dac, with a 1/8 to RCA plug into the speaker.
Any ideas what this could be? could something as little as a dirty USB port do this?
