Cables recommended for Sony based system?


This is actually for a friend of mine who is piecing together a HT set-up based on the DVP-NS999ES and STR-DA5ES receiver. His speakers are Linn Keilidhs with Klipsch center and rear speakers. He is presently using $30 IC's and that clear jacketed speaker cable from the hardware store. He is looking to upgrade and has asked me for my opinions but not being familiar with Sony stuff I ask you for your thoughts. His budget is about $100 per set but I'm trying to raise that being a bit of a cable freak myself.

Looking for recommendations for IC's, PC's and in the wall speaker cables. I have been recommending Kimber Hero's, 8TC and pro-Ac 11's but could use other ideas. Nordost too bright?
Also, any thoughts on multichannel cables?

Interesting. I think I will warn him about this. I think sibilance is one of his pet-peeves so it might be good to send him in the Cardas direction. The GC will be too much$ so do the lower end of Cardas share the same properties?
I would recommend AZ WOW IC instead of Cardas, it would be cheaper and better and still very smooth IMO
I tried out the AZ ref matrix II and didn't care for it much in my system. Way too clinical. How does the WOW compare. I had similar experiences with HT in that I liked the truthlink over the Pro-Silway II.
