I bought a 6300 at Dayton and it is working great except for one little problem. When I power down the radio by pushing the front panel on/off button my speakers, Klipsch Pro Media 2.1 emit a loud pop when the radio goes off. It is not a big issue but a little annoying. If I remember to turn the speaker volume way down before shutting off the radio it is not as loud but still there. Anyone else having this issue?
