Cables for B&W 805S

I'm using a Classe CAP-2100 integrated amp with an Ayre C-5xe source. Have gone to the 805S and wanted to ask for suggestions. I've searched the archives and haven't seen much mentioned for these monitors regarding cable. I'm using the dedicated B&W stands and want to be able to run the cable through them so don't want a thick cable. I'm currently using Purist Audio Venusta bal interconnects and PAD Opis speaker cable which sound great but they're to short (and thick). I've been thinking of Audience AU24 but have not heard them in my system. I might try borrowing from the Cable Company, but would like your advice on a higher gauge cable thats worked well for you. Thanks!
