Touching on some of the points mentioned: as Mike and Doug pointed out, the 3806 is another of the receivers that can set separate crossovers for separate speaker groups; the jury should be in that current Yamaha receivers do fine in most situations at 4 ohms, as tests indicate 4 ohm power in the 150-200 watt range; whether any player, receiver or separate unit does deinterlacing and/or scaling may be meaningless if the deinterlacing/scaling that the HD TV set itself does(it has to)is good enough so that having the processing done instead at some earlier point doesn't result in visible improvement.
