I bought the Onkyo TX-SR604B as a placeholder receiver, and I'm running 2 M80s, 1 VP150, and 2 QS8s as well. I haven't had any problems. It's so light compared to the Sony receiver I was using before, which made me wonder, but it seems to be up to the task. But yeah, it's definitely a placeholder, as I'd like to have something that can switch between at least 3 HDMI sources, preferably 4. It looks like one of the new Onkyos will work. I'm still considering a separate amplifier, though, because spending money is fun. Ha ha. I'm sure JohnK is shaking his head now.
