I would stick with the Anti brand if you already have and like their speaker cable. IMO you can't go wrong with the same brand wiring your entire rig. Likely, you'll be fine and experience no RF interference. I myself run unshielded cabling in my entire system (one brand also) and have never experienced any hum or RF issues with a number of different components, both SS and tube.
Anti has a return policy, no? Nothing to lose and worth trying I would think.
