Aftermarket fuse to tame a bright system?

Been reading all the interesting posts here, I've recently switched over to Audioquest silver interconnects and speaker cables, the improvement is easy to hear over OCC copper - lower noise floor, more clarity, greater transient snap, larger soundstage etc.... BUT.

I would say my system still has body, but the top end is now bright/harsh.  Could an aftermarket fuse tame this, so that I can still retain the clarity and other benefits of silver? I'm concerned that this potential solution may make my system more dynamic, and potentially give it a U or V shape sound profile - which is definitely what I don't want.
