Sorry, I might have read your post too quickly, but what I heard was that you want to keep the resolution you have and add a tad bit more warmth to the sound. Not necessarily a softening of the top end as much as a cleansing of the top end and perhaps a tad more midrange/midbass warmth.
The Kaplan copper power cord will add this bit of warmth for you, and perhaps add some additional transparency as a bonus.
The Kaplan conditioners and power cord combo might assist even further with a cleansing of the top end by reducing further AC related grain.
However, you will need to try them in several places (amp, source, preamp) to see where they would work best and do the most good. There is probably one component in the mix that is the primary source of this unwanted grunge.
Enjoy,
Bob
