Well, I finally took the plunge into a 21st century HT/sound system. Picked up the Onkyo for $510, online, on Black Friday special, after researching multi channel receivers for several months. I thought the holiday season is a good time to swap out the equipment, and maybe have some vacation days to give the new system a workout. The 709 replaces an older Onkyo 8511, its a 2-channel receiver that will be moved into my home office. Got the 709 hooked up tonite, but lots of fine tuning to do, including getting the wireless adapter working. Set the cable signal to pass thru to TV when receiver is off. Bought all cables at monoprice.com, very pleased with the quality of the cables, tho, all made in China (ha, like everything else . . .) Was ambivalent with the music sound on initial listening, but haven't run Audessy yet. The Polk sub replaces a 15-inch passive sub that still performs impressively and is headed for Craigslist! I appreciate this forum, I read/learned a lot here before making the receiver purchase, and may post some questions as I go about fine tuning this new system. I'm looking forward to streaming content from my laptop to the system, and running internet radio . . .
