I have no experience with XLO or Magnan, although I've heard both are good cables. I owned Martin Logans for years and used Kimber 4tc, which is very affordable. I had excellent results. I used 4 runs per speaker. Two runs on the top and two on the bottom. In theory, this would be the same as biwiring with Kimber 8tc. However, I tried the 8tc and liked my version much better - the bass was cleaner and tighter. If you read the reviews, you know the Kimber 4tc (or 8tc) are very good bargains that are known to outperform much more expensive brands.
Note: I was just reading about Home Depot Wire! Seriously, read about it for yourself on Agon or Audio Asylum. I had a conversation, via email, with a true audiophile how uses it on his very expensive system and swears by it. I'm not going that route, but it is definitely something to think about!!
Good luck.
