Need cool running integrated under $1500 new/used

I have a second system with a old pair of B&W 803 series2, and I need a cool running integrated that can power these (maybe 75wpc and up?). I want to be able to leave the amp on 24/7. I currently have a Cambridge 850 that sounds great but gets very hot. So, going to replace the Cambridge, but with what? I would prefer an integrated with two speaker outputs (A+B and A or B), but open to all suggestions. Thanks much...
