The Okyno 806 is a good choice as long as you give it room to breath but unless you realy need it's upscaling abilities due to legacy equipment you may want to save some money with the Denon. Rather than the Denon AVR-3808CI try looking at the Denon 2809CI(new 2008-2009) or even save some more with the 2808CI (2007-2008) as it is heavly discounted right now. Both have the same guts basicly just a small diff in wattage 110 vs 115 a few more HDMI inputs and a newer GPU. All of the above I have seen and heard running 4ohm 86db and up speakers with no problem. They are all rated for it and have bridging capabilities,the Denon 2809 even on the surrounds along with multi zone if you would rather.
