I'd recommend you not spend big money (> $100) on interconnects, your system is not going to benefit in any meaningful way.
I agree with Rlwainwright.
VH Audio Pulsar, used for under $100, are very good interconnects, as are any
of the Mogami
interconnects offered by KAB Electro Acoustics (click on the "ART
Cables" link in the right column).
