I'm not going to recommend a specific brand (why stick the neck out) but one piece of advice: Whether it's Purist or VD or Elrod or Belden or any of dozens of others, just make sure it has at least 10AWG conductors. I think Audioquest or maybe it's PS, make 9 and even 8 AWG PCs. Wouldn't hurt if it had a floating shield either, but not imperative since the conditioner should remove any noise.
