currently i have set up the two front towers, have to do some mods to fix the surrounds and center so for the time being listening in stereo mode, i have to say im mighty impressed with the AJ's even without a sub its giving me adequate amount of clean bass, which i absolutely love, am yet to get my tv and Blu ray, should be getting them in 2 weeks before sept, no wonder there are rave reviews about the AJ's they are awesome, im playing mp3's now and even they sound awesome, am yet to explore the options of the denon x1000 sure i can improve the quality adjusting the settings on receiver
