I would make my own cables from 16 awg Duelund DCA wire. The wire for a 40' set will cost you $400. A good set of XLR connectors is $100. Sheath material another $100. If you don't have silver solder, another $15.

Really Long XLR
Looking to move my front end gear to the side wall in a new listening room. If I don't want cables running across the floor in front in my speakers etc., then I'm going to need a set of XLR interconnects in the 40 - 45 foot range. Wondering what other members have done and what cables have been selected for a very long run. Obviously the companies asking $$$$ for a one meter set are not in the running. All suggestions are welcome. Not afraid to build my own if anyone has had great experience with bulk XLR cable. Thanks.
