Listen to both and decide for yourself. I have never heard a Yamaha receiver, but I do own a NAD C352 Integrated amp and I love it. One thing is for sure, the NAD will provide the stated power it advertises. I know my 100 watt Pioneer is nowhere near 100 watts. I believe that Pioneer, Yamaha and Denon will not drive 5 speakers at the wattage they advertise. Harmon Kardon, NAD, Rotel and others do.
