Wow, I wish I had your hearing . . .
I hear what I can only describe as a bit of a faint high frequency sizzle, which I attribute to simply what the guitar sounds like. My hearing isn't acute enough for it to bother me but I have about a 30% loss there.
Pic on left is pre-adjustment. I definitely see your 1000 hz spike and you did reduce it nicely, but along with several other spikes - but that could be that one strum.
There's always a possibility that you have a slightly high buzzy fret. Is it an open chord or are you up on the neck with a capo? It's possible you might ameliorate the sizzle with your fretting technique - either a softer press or shift your finger closer to the fret wire, but it may well be that being a Taylor, you have brightness. . .
@Edward - on my Mac I was able to control-click the icon and it downloaded, I imagine a PC would have a similar technique . . .
