By the way, I tried out the Kernal Buffer change you mentioned in the ASIO4ALL config utility, but I wasn't able to observe any change in the trebles.
Ultimately, I think Dodeca has probably properly diagnosed the situation when he said:

There are times while working within my DAW that I'll need to change buffer sizes, and if audio is playing, there is a varying degree of effect depending on my processor load.
This could potentially explain it.

Then again, Foobar doesn't seem to allow for a change in buffer on the fly, and the two audio-asylum posters who claim to observe the same effect were apparently using both Foobar and Winamp.
While I understand that buffer should have no impact on a "bit perfect" stream of digital data, my question is really whether the buffer might potentially impact clocking/rate of transmission of the data, such that it could possibly impact my perception of sound stage?
There seem to be wide degrees of variation in jitter and proper clocking in spdif signals based on the implementation (and I would assume the X-fi isn't particularly strong in this respect) - does "bit perfect" entail perfect clocking? Is there even such a thing?
I didn't have an opportunity to try the DTS test through my receiver this last weekend, but I'm hoping to give it a shot in the near future.
