Belden 1800f and Emotiva XPA1

I've just installed the Belden 1800f in my ceiling and then read that Emotiva recommend not to use twisted pair cables as IC. I have Emo's XLR cables at both ends (Emo's XLR from preamp to wall jack, then the Belden cable to the other end jack and then again the Emo' XLR to the amps) and there's no problem, sounds great. Any advice?
