    Hi all,

    I have just bought the Acoustic Energy Aego sat/sub speakers for my 24" iMac...and excellent they are too. A HUGE improvement on the built in speakers.

    However, I occasionally get an electronic 'pop' or crackle from the satellites. Only happens occasionally. If I plug the speakers in to my iPod (2nd gen) all is perfect, so I assume the iMac is picking up interference from the mains or network and passing it on. Anyone go a similar problem?

    I assume my options are to try a better gangway adapter (or UPS) with noise filtering, or perhaps (but this seems a bit overkill) a USB audio output device rather than using the iMac audio out.

    Any advice much appreciated. I cannot begin to describe just how much better the AE Aego's are, but the interference is annoying...

    I'm going to revive this again as well!

    I recently connected up the same speakers to my 24" imac, and I am getting a slight interferance and a loud hiss/cracking every now and then, almost like feedback.

    Any ideas?

    A similar thing is happening to me with my macbook pro and Fostex PM0.4 studio monitors.
    I believe it has nothing to do with the speakers themselves (simply because I hear this popping noise when using headphones as well)
    It seems like after a period of no noise (music or sound effects) the external sound output will "disengage" and then re-engage immediately before use again.
    The result is a loud static popping noise.
    I am finding this increasingly annoying.
    Anyone know how to fix this?

    Possibly.
    I have had this issue on a 24" and my new 27" i5 iMac. First was with a set of JBL Creatures and more recently a pair of M-Audio AV40's. I bought a new APC surge protector with RF filtering and plugged the speaker's AC adapter in it and left the iMac plugged into to a different APC surge protector. That seemed to resolve it. I recall it has something to do with a current loop.
    I think the underlying issue is Apple using a less than robust Audio jack.
    My older PowerMac G5 had a similar issue come to think of it!
