I am looking for a receiver and have narrowed my choices to the Harman Kardon HK AVR-254, the Onkyo HT-RC160 and the Sony STR-DN1000. The pricing is similar, with the HK being a refurb (the other 2 are new) and about 60 cheaper. I have a Sony PS3, a Comcast/Motorola HD cable box and a Wii along with a Sony Bravia 46 inch LCD. The only upscaling that will be done is to the Wii, along with the SD cable channels if the receiver does a better job than the cable box and/or the TV itself. For speakers I have a small Cambridge Soundworks 5.1 system with a powered sub. How do these 3 receivers compare to each other? Which is the preferred model and will give me the best performance with the most reliability? All opinions are appreciated.
