First, Disclaimer I am the owner of PNF Audio.
The main concern you should look at is the gauge of wire in the speaker cable you are looking to purchase. Because of the length of your cable run, you want a larger gauge internal wire (resistance).
I just did a system for a guy with two sets of 25ft runs of Symphony Speaker cable and three sets of Icon interconnect. The system was Mcintosh gear and Avalon Speakers. We get a good bit of business since we offer custom length cable. visit the site and read the Editor's Choice award for 2007 from the Absolute Sound Magazine.
