    I'm noticing a very slight static-type noise in my front speakers at a very short frequency range. It appears to be near the upper end of male dialogue. This is a VERY slight thing and I only notice it every once in awhile. However, I've noticed it enough over the past 6 months that I don't think it's my imagination.

    What could cause this sort of thing? I'm running two relatively new Axiom m2i's, so I don't think the speaker is the culprit. Also, I can't seem to reproduce the noise while playing a frequency sweep tone.

    Here is the path of my sound:

    HTPC (Augidy 1 S/PDIF out w/ 75ohm cable) ->
    Pioneer 811S receiver ->
    Speakers

    I'm guessing it is a source problem, since I can't hear it in my surrounds, but they're el-cheapo speakers currently, so I wouldn't expect to be able to hear a subtle detail like that in them.

    Thanks for any help!

    are we talking about sibilance? is it the way certain letters are pronounced, like s's?

    No.. it's definitely not that.. I've noticed it on other sounds than human voices, I just wanted to give an example of where I usually hear it.
