I think that this topic has been covered in depth many times over. Anybody that has done comparisons will tell you that SS amps sound best after being on for at least 24+ hours. They also last longer being left on all the time (all things being equal ). While LED's can last a long time, i wouldn't count on them running anywhere near "forever". I would worry more about capacitors than i would LED's though, especially if you are turning your amp on and off. Sean
