Bright & fast speaker cables with great imaging ?

I need some tone control for my single driver speakers which lack in the treble department and want to get the most detail out of them. The speaker cables should lead to more present cymbals and an open soundstage.

I value timing and imaging and openness the most.

Budget 400$ used.

I am open to amp and interconnect recommendations. (92db/8Ohm/small room)
