Interconnect/Speaker cables

Hi all, Newbie here with a question. My set up will be components which I was given which include the following: 2 class " A" N.E.W. amplifiers and a N.E.W. tube preamp w/ an East sound cd-5 cd player. I plan on using magnepan mmg's bi amped and would like to know any suggestions on mid-priced interconnects and speaker cables that will give me the most bang for my buck. Thanks in advance.
