OK, I'm going to get anal about this :-)

So far I've controlled for the following variables, each with no discernible effect on the noise:
- Sound card driver versions (tried 3)
- Master volume levels, software amplification levels, and external amp levels
- Listening to the Ambient channel for similar levels in the tracks (no noise noticed aside from "correct" groove noise, effects, etc.)
- Local playback of tracks with similar levels (no noise)
- Local playback of known matching tracks (e.g. Cardamar/Marco Torrance CDs), on multiple systems (no noise)
- Switching from front-panel output to direct output on sound card (noise still present)

Variables I still need to control for:
- Final presentation of audio (swapping speakers and headphones)
- Preamp, amp, and decoder in second audio system that has this problem
- Double-check on my 3 available systems to see if all exhibit the noise

It'll take a while, but at least it's enjoyable drudgery... should have some additional info in the next day or so.
