I am going to go against the grain here. For interconnects, I would recommend you try the Radio Shack audio cable before buying anything more pricy. These are black color cables with gold plated RCA connectors. They are very cheap and sound quite good. I have compared them with Cardas Natural Reference, Alpha-core TQ2, Harmonic Tech Pro-Silway II, and Acoustic Zen Silver Reference.
When I connect my SACD player to my preamp with them, I can honestly tell you that the differences were very subtle if any at all. I heard more profound differences when I use them as tone-arm cables and use them to connect phono and preamp. But in your setup, I dont think you will hear any difference unless you compare them with something very high-end.
Actually, I have a spare pair and if you want to try it out, you can have it for free.
