Help with Home Audio: I'd like to know if the Crown XLS 2502 need to be plugged into a dedicated 20 amp outlet or can I get the maximum output from a 15amp socket. I have a pair of Triton Reference that are 93.5 Db efficient with a maximum power handling of 600 watts, in a dedicated theater room, and I want to push them to their limits. I'm just not sure what power source I need.
