Cable & Interconnects for a Plinius 9200

Graduated from a Creek 6060 to a Plinius 9200 and am soliciting cable & interconnect recommendations.

I have limited range (i.e., not full range) Triangle Antal ESWs.

I have the old Acoustic Research 130T interconnects that Sam Tellig pitched 4 or 5 years back in Stereophile (my first non-factory interconnect, and they were indeed a revelation).

Just using Radio Shack copper speaker wire right now, looking to replace as well.

I am told that Blue Heaven can compensate for the darkness quality associated with the Plinius. It can't be that easy. Any help much appreciated. My cable/interconnect budget is $1,000.
