I have a Bryston B100 with the C1's and it did take a very long time to decide on my speaker cables but I did choose the Nordost Frey. At first listen I thought they were 'thin' sounding but after several weeks I realized I really heard the 'air' between the vocals and instruments. Better attack and decay. Very relieving!! I did have a Nordost demo case for cables for 8 weeks which gave me time to make a decision. I've had the cables for 11 months and would only consider moving up in the Nordost line.
That being said I also really like the Kubala Sonsa Emotion speaker cable but it reminds me of a fire hose not garden hose and is very heavy. I personally didn't want too much pulling force on the speaker connectors.
As far as IC's I use the Fusion Audion Interlocker II which is a little forward but at least for me it mates well with the Frey speaker cable.
It's your money and everyone has a different taste in type of sound. Ideally try to demo cables in your home on your system.
Most important have fun.
