Thank you for the replies.
I think I need a true AV receiver rather than stereo receiver, because it is in my living room and used for TV, also i would prefer one with HDMI input.
The Marantz SR5005 is to expensive, however Onkyo TX-8050 Network Stereo Receiver is 260$ and in the price range. Why is it better than other receivers out there, for example Onkyo TX-NR509 5.1 Channel Network A/V Receiver (239$)? Can 5.1 or 7.1 be used for just 2 speakers? What exactly to look for in specks?
