Marantz lets you do that as well and maybe even Denon. I do love Yamaha as well but not as crazy about YPAO but I do love the Yamaha sound and build quality.
I still have my SC-05 and I do not remember it getting to hot and I remember the 05 using the ICE amps and that they did not deal with 4ohm loads well. I currently have a Marantz SR-8012 and I love that receiver and do not plan on replacing anytime soon. I do really like the Yamaha receivers...
With what Denon and Marantz are offering I am not surprised to see them making the list in multilple catagories. That being said there are lots of great options from Yamaha as well. I may own a Marantz but Yamaha was on my short list as well when I was shopping for a new receiver.
