I'm thinking about doing the same Ken. I have a HK247 running M60s in a 7.1 setup. Although it does great for me, I think it strains (mainly the center) a tad bit when I listen to movies at high volumes. I do like my receiver, but I am looking for a cheap alternative to give my HK a small boost.

2 = M60,4 = QS8's,1 = VP150,1 = EP350,1 = EP500
