I just bought a set of Bose Companion 2 speakers and placed them on my desk near my Mini and 2407-HC and am happy with the performance of the set. However, I noticed a hissing sound when no audio was being output. Blah, I thought I must have gotten a bad set. Yet, I starting thinking that maybe it was too close to my monitor/Mini. So I started moving it around and playing with their proximity and orientation only to notice that I was able to minimize the hiss. So my question is: Has anyone experienced this with any type of speakers (and more relevant Bose C2)? That the proximity to other computer components effected static noise? Thanks!
