FWIW, a number of studios, at least the independants that I am aware of, use Canare and Mogami cabling extensively, for everything from mic cables to interconnects, to speaker cables (though most use primarily powered monitors, so not much speaker cabling going on). Following advice which I received from several engineers, I have set up my home studio with mic/instrument/interconnect cables made using Canare or Mogami cabling and Neutrik terminators. I picked up my from PerformanceAudio.com. Their prices are very competitive.
Hope this helps, Tom.
