Hello everyone this is my first post. It has been thirteen years since my last purchase of my last AV receiver a Denon AVR 4800. Now technology has now caught up with me. I have used up all my HDMI inputs on my TV monitor and now I have four devices that use HDMI two HD DVR'S one Blue-Ray player and one xbox. So it is time for a new AV receiver. They will be connected to Paradigm Studio towers speakers with center channel. I want to be able connect it to my home network, steam music from my NAS, be able to connect ipad, & ipod most important of course good sound quality. Receivers I am looking at the Yamaha RX-A820 and RX-A1020 the Pioneer Elite SC-61 the Onkyo TX-NR717 and the Denon AVR 3313-CI.
