Finally - They're out. Onkyo (USA) just released the following on their replacement X1X series for the 709 and 809 AVRs. See press announcement here. The biggest news 9for me) is that the 818 will have Audyssey MultEQ XT32. A big step up for those wanting finer calibration of their subwoofer(s). The fiull list of features and specifications along with pictures can be seen here. Enjoy!
