You already have excellent components.
If you still want to make a significant difference in SQ, for far less than $10K, consider a BACCH4Mac package. It's about $1K for the basic software (and set-up consultation(s)), plus the cost of a Mac (Mini/other) if you don't already have one. This product minimizes/eliminates crosstalk to improve the soundstage/imaging. The effects vary depending on the recording, but on some content can be rather dramatic.
