Speaker connection

I will be hooking a MC MA6500 to a pair of SF Domus Grand Pianos. Need about 10-12 feet per speaker. Whats are some of the cables I should consider?
Coincident TRS Extreme or Westlake Audio are the best I have come across regardless of price
Analysis Plus 9 is very respectable and I've run alot of wire over the decades. For less money Signal Cable is very difficult to beat.
