30 x 20 is a big room (I'm assuming 8' ceilings), and even with the NAD I'd consider gettig an external amp for the fronts if you are using 4 ohm speakers and like it loud.
I knew what test u were referring too. They make a few silly mistakes in it like saying the front display does not dim when it inded has 3 settings. They also do not mention where the Ohm setting was set to during the test. But they claim that test was with 5 channels running. I don't think the test holds any weight with me anyways. I have had one amp witha true 110watts and now the Yamaha, and there is hardly a difference. the yamaha gets a little warmer, but it also has 4 LESS fans.
