Planning to move my entertainment center to a stairway closet and wire for speakers and Monitor. Now, should the speaker wire per channel be of same length? I have to run couple of 20 footer and and three 35 footer wires? What gauge of wire should I go for? 12ga? Will I loose picture quality if I run a long (close to 35 feet) component cable from my cable/AVR to Monitor? Please let me know. Thanks.
