I have used Kimber 8TC, Bi-focal X, and Audience Au24s. First of all, I don't think you should bi-wire. I really like the single wire on Maggie 1.6s. Bi-wiring really isn't worth it and I'm sure most Maggie dealers would tell you the same. I tried it with the bi-focals and it was nice, but I prefer the Au24s. As others have stated warm, MUSICAL cables are the best. I really like Dan at Dedicated Audio. He is helpful, honest, and very reasonable. He carries Audience and Cardas. George Cardas is a Maggie user. Dan will probably tell you Cardas over Audience. Regardless, I think either would be great. Good luck with your great speakers
