Yamaha HTR-5790 7.1 Channels Receiver

I recently bought this product from ebay... After months of dreams of a kick@$$ system while I was in Iraq and reviewing epinions on many others, I decided this is the one that would work for me... I had upgraded from a 5.1, which I loved, that I had for over a year... and after acquiring much deserved money from the deployment, I decided bigger and better... I haven't played around with it much or read the manual, so I guess I have myself to blame on certain difficulties on how it fully functions and use it to the best of its capabilities... But it is freakin awesome!!! The highlight of my day after playing soldier is to come home and just be surrounded by its amazing surround sound... hehe, I said surround twice... well it deserves it... I play a lot of video games, mostly shooting games and rpg's, and trust me when I say sometimes it feels like I'm back in Iraq... "Surround" is the key term here... I'm happy...
