Which cables for McIntosh - B&W system?

I'm sure there are a lot of Mac and B&W owners over here. My set up will most likely be Mac 301-46-402 with B&W 802D or if the finances allow 301-500(solid state version)-501 with 802D. What cables should I use through out? Right now the only decent cables that I have is a pair of Shunyata Pythons PCs so one of the options is to go for a full Shunyata set up. The other ones that I'm considering are Kubala Sosna and possibly MIT. I need cables with open neutral sound (as the Mac/B&W D combo is allready perfectly balanced and not bright), great TIGHT bass, extended highs and huge soundstage. Cables that doctor the sound in some direction or another (like Nordost or Cardas for example) are not what I'm looking for. Synergistic Research (which I'm sure a lot of you guys will recommend) is sadly not available where I live and difficult to audition. Any ideas?
