ok, so i think i've got the bass for the first two minutes done. i know, i know - but i'm neurotic, i'm sorry. i actually ended up neutralizing the headphone buzzing by swapping the earpieces out. right-brain/left-brain discussions are not science, but my right ear is definitely stronger, so i notice the buzz less by placing it on my left ear...
i'm still apprehensive about it, though. so, i'm going to ask a favour of the 36 of you. if you could head here and download the track (it's just a file) and play it through as many systems as you can looking for a buzz or rattle in the bass, and then post the system you used to find or not find the buzz or rattle, that would help me chill out a bit.
