Make sure the 828 has Audyssey MultiEQ XT32 and not a lesser variant.
I have done a bit of digging. Apparently, the 828 is not the step up from the 818 for exactly that reason, Tom. The 929 is the upgrade from the 818 as it does have the better Audyssey. So, Bluetooth is the main advantage - so you guys are saying that hooking your Iphones up via Bluetooth does not sound good? To Murph's point, apparently I could control the receiver with an Ipad (if I had one). I am not sure that is worth the additional $200
