I've implemented the Auricap tweak in several DIY mods to digital players and DAC's. In each case I've always put them AFTER the fuse, just in case there is a blow out. You really don't want a short, no matter how well the caps are rated. It could cause you your house, since you are volurantarily implementing a hazardous situation, and the insurance company could invalidate any claims.
Basically it isn't worth the downside to get a little better resolution, unless you implement it with a proper failsafe, or use X rated caps (which is what is inside the Quiet Lines).
Enjoy,
Bob
