High-quality in-wall XLR cable?

Can anyone suggest a good quality balanced cable that is reasonably priced, for in-wall and through-attic use? Run will probably total around 40 ft, so I would rather not run that much speaker wire. I can terminate it myself, so buying bulk wire is not a problem. Thanks!
I used Wireworld microphone cable Meteor or Orbit III+ XLR terminated 41' for $400.00
