Which is the bestPS Audio cable to use for AV5000?

I would go with a Statement from the previous generation; at least 8 guage and they are avalable new on ebay for under $200. I use one on my PS Quintet.

I have the Statment Sc, and while its an outstanding cable the new AC10 or AC12 will yeild better results extended highs, fuller mids and much deeper bass than the Statement Sc. While I have'nt tried the Ac12 I have an Ac10 and at 10 awg it beats out the Statements 8awg in all the areas above. And from what I hear the AC12 is only gets better. If you got the bucks get the AC12 or AC10,as I'll be replacing my Statement with the AC12 or another AC10. hope this helps.
