In addition to Signal Cable or Blue Jeans Cable you may consider Canare Star Quad 4S11 available as DIY or assembled from haveinc.com. These are all good cables that give a more neutral signature.
Many of those "expensive" cables are more apt to give their own sonic signature.
p.s. very nice system you have going - congrats!
