Kimber 4TC would be something to consider. Watch for a used pair on Audiogon. You want the teflon coated wire. It's much better then the 4PR. DH labs T14 is also good. It has silver plated copper, so highs are going to brighten up. You may or may not want this. Bannana connectors are easy to swap and compare different wires.
You should also play with interconnects. Stick with known brands like Kimber, Analysis plus, Cardas, Nordost etc... You can re-sell and get your cash back. DIY cables might be cheap, but re-sale will be poor. Do searches for budget cables or interconnects in the forums. Use words like "value", "budget", "cheap" and "bang for the buck".
Be more specific in your question. What sound improvements are you looking for? What is your budget?
