Cable Suggestions

Looking for unbalanced I/C suggestions. My current system:
B&K ST-1400II amp
Quicksilver tubed linestage
Sony CE775 SACD
MSB Link DAC
Magnepan MG-12

I'm currently using Kimber PBJ I/C's and 8TC speaker wires. The system currently has too much high end detail and not enough warmth. I think the PBJ's are the culprit (I doubt it's the electronics).

Looking for an I/C that will impart a touch of warmth/lushness. My budget is @ $100 per cable (new or used).
