XLR cables for high-end multichannel system

My system comprises 5.1 Focal Electra 1028 Be II based speaker system with Sim audio Moon MC-8 multichannel amp and Onkyo 5509 pre (may upgrade this) and soon to be added Audio Research DSPre for 2-channel. I'm looking for advice on suitable XLR cables which are fairly neutral. I don't really want to go into the stratosphere in terms of price (as I need 5 to 7 of these!) but, so far, contenders are:

- Audioquest Sky or Niagara
- Kimber 1126
- Acoustic Zen Absolute

I've also read good things about Siltech, Silent Source and Shunyata research.

Advice/thoughts on the above or other possibilities gratefully received!
