I can only respond in general to your question, since I am not familiar with components in your audio system. However, there are several budget interconnects and speaker cables that I have used and like. Start with Kimber Kable's lower-priced stuff, such as the PBJ interconnect, or maybe the Hero. Kimber's Silver Streak is also an excellent interconnect and you can sometime buy it used for around $125 for a 1-meter length. For speaker cable, I suggest you start with Kimber's 4TC. It's good, fairly neutral, and the best buy at anywhere near the price. An option you might want to consider is interconnect and cable made by a fairly new company called "BetterCables". The owner of the firm builds all his cables as they ordered, to spec. I recently bought 3 different kinds to try: a component video set, a S-VHS cable, and a digital coax. I was very impressed with the build quality and performance-for-price. There are now a number of reviews of "BetterCables" on AudioReview. You should take a look at their Web site for more info: www.bettercables.com
