Just made a very difficult decision; I have decided to purchase the Onkyo TX-SR707 receiver and the Onkyo SKW 204 subwoofer. The primary reason that I chose the Onkyo over the pioneer VSX-1019AH-K was because the 707 was THX certified. I am going to be using older Bose and Sansui speakers until I can purchase a matching system. I just hope I will not be disappointed in my decision. Any thoughts or suggestions?
