I too own a Halo A21 in one of my systems and love it. Anticables work, I run AC speaker cable in two systems and some of their IC's as well. I have a mish-mash of cable, some Shunyata, some Jungson, some JW Audio. The Shunyata is best and can be considered 'affordable' if you visit Weekend Environments and check the specials. That said, the Anticable works very very well. Associated equipment includes First Sound and Parasound JC-2 pre amps, Sonus Faber and Talon loudspeakers, Bel Canto and A21 amps, among other gear.
