Consider Blue Jeans Cable. They will run you about $250 for the pair.
I've used Blue Jeans interconnects, speaker cable and XLRs. The quality of construction is first rate. (Ultimately I replace the speaker cables with Kimber 12tc)
I run a BJC Belkin 15 foot XLR from pre to power and I am satisfied. Worth a try, I think.
Before you spend $$$$, anyway.
