one thing to keep in mind is that with more revealing/unforgiving cables, be it the ICs or the speaker cables, you will reveal the flaws of your electronics and speakers. Just try to keep the cabling on the same level as the rest of your system. FWIW, my speaker cables cost around 25% of the price of the speakers and I am very happy with their performance.
P.S.
You'll probably notice bigger improvement if you upgrade IC from source to pre than you would notice by upgrading speaker cables. Is there a reason why you're not using the Nordost ICs?
