Well currently my old JVC 5.1 reciever is showing its age and lack of quality. Im looking to upgrade to something better, preferably with the ability to do 7.1, though i plan to use it only for 5.1 surround right now. Also 100 watts per channel would be nice. HDMI abilities and an on screen control would be nice but not necissary, as well as a speaker calibration tool. I should also mention im hoping to stay around or preferably under 500 bucks. So far ive been looking at Harman Kardons and Onkyo recievers. Onkyo seems to be the best value and able to fill most of my needs.... im just unable to narrow it down to a single reciever. Any recommendations?
