My Denon PMA-915R integrated amp has both switched and unswitched AC outlets. The switched outlets are rated 240W, but I have no problem running 450W of lighting through them; it's so much easier to turn on the amp and have the lights come on at the same time. The rating is in your owners manual. Burn baby burn!

BTW, I've come across an old JVC integrated amplifier with AC line conditioning through their AC switches. Maybe your Denon might have it also (mine doesn't).
