Hi all! Brand new to the forum! I currently have a 5.1 Onkyo system that's about 10 years old, so I am looking to upgrade to something a little newer. My current setup: [*]42" Samsung HDTV [*]Onkyo 5.1 Receiver (generic 5.1 receiver) [*]Klipsch center, main and surround speaker [*]PS3 [*]Roku [*]Cable Box [*]Klipsch subwoofer [/list] I like the sound of the speakers and all my products in the setup, but I am looking to run all HDMI cables to the receiver, out to the HDTV. My current receiver has no HDMI input/outputs, and I am looking to somewhat future-proof the setup a bit. So my requirements for a new receiver.... [*]HDMI ports (I assume I need one with passthrough - do I need 4k enabled passthrough?) [*]Optical and coaxial audo inputs [*]7.1 channels (if possible, and worth it) [/list] My budget is a bit modest, however. I am trying to keep it under or around $400-$500 total for the receiver. Any and all ideas are appreciated and welcome! Thanks in advance for any help!
