Well, I've finally upgraded to a true 5.1 surround system. So, in addition to my existing television...

Connections The speakers are connected with speaker wire from Aperion using banana plugs, also from Aperion. Although using the plugs took more time to set up, it seems worth it. It makes for a simpler and cleaner connection from the speakers to the receiver. The sub is connected with subwoofer cable Aperion also provided; it has a single connector on the receiver’s end and is split into right and left connectors at the sub’s end. The TV, PS3 and DVD player are connected via HDMI cables. The DVR/cable box is connected via component video (3 plugs on each end) and analog audio (left & right; 2 plugs on each end). I may upgrade this to an HDMI connection in the near future. * Questions Though I’ve certainly started to enjoy my new surround sound experience (Inception and The Tree of Life were the among the first test titles) I have a few questions. I feel as though the output (volume) from the center speaker and subwoofer are, for my taste, a bit low compared to the other speakers. What are some good ways of adjust the output for just those speakers? While the AVR-1912 receiver sports a built-in Ethernet port, it does not have a Wi-Fi dongle. I would like to somehow add it to my existing Apple Wi-Fi network so I can take advantage of its network-based services (AirPlay, iTunes, etc). I have an Apple iMac desktop computer, which, like other devices in my household (e.g., my printer and my PS3), is connected wirelessly to my cable modem via an AirPort wireless router. I understand that it’s possible to “work around” the receiver’s lack of a Wi-Fi dongle and connect it to a wireless network indirectly. How, exactly, would I do that and have a high-quality, reliable and fast connection for the receiver? Would an HDMI connection substantially improve the picture & sound quality of cable broadcasts and recordings beyond my current connection (see above)? I’ve noticed that I do have surround sound even with my current connection. What HDMI cables would you recommend, considering quality and cost? Generally, I look for high quality but with a reasonable price point. There are times when it would be nice to be able to use two headphones simultaneously, but the receiver has only one headphone jack. Are there any devices that would allow me to connect two or more headphones into the receiver? What else should I know if I do that? * In the Future I still have more improvements I want to make to my home theater system in the future. (Don’t we all? ) Very Near Future Additional HDMI Cables (for my cable DVR, old DVD player and future blu-ray player) Speaker Stands for the two 4B satellite speakers (the speakers need to be higher) Near Future Region-Free Blu-ray Player (another item I’ve been wanting for a long time—I already have several locked-out-of-my-region titles) Maybe within a Year Larger Subwoofer or Second Subwoofer Perhaps Next Year New 60-inch Plasma Screen TV (maybe with 3D) …One can dream, right? * Anyway, those of you who can, please answer my questions above…as I go back to playing around with my new toys.
