I can get the Panasonic SA-HE200 for $100 cheaper. I listen to Home theater about 40% and music 60% of the time. Both receiver have similar features and are in my price range of $500. My concern with the Onkyo TX-SR600 is it its 80 watts x 6. My two front speakers are JBL rated a 200 watts. Will the Onkyo TX-SR600 be able to push my JBL's? The SA-HE200 is 130 watts x 6. Does wattage make big deference? also I am not sure if the Onkyo TX-SR600 has a A&B switch. Thanks in advance to any one that can help me out.
