Fair questions and points.
@gdnrbob, because I'm also breaking in the speaker cables, running at higher volumes for 10 or more hours a day just isn't possible, especially since I work from home.
@taww, I did set a play list of about 10 hours worth, and going with Elizabeth's suggestion, I'm running in the ICs, but I do need to also work on the speaker cables. Is the 100ohm resistor something I could pick up locally? Someone also suggested a 200watt light bulb... would that work?
