Your system is of sufficient quality that I suggest you get cables that offer a high performance-to-price ratio. The Alpha-Core Goertz MI2 speaker cable would be my first recommendation to you, followed by the Kimber Kable 4TC.
For interconnects, I'd suggest any of the following (in ascending price): Kimber Hero; Nordost Blue Heaven; Synergistic Research Alpha Sterling.
