The bluetooth&wifi option actually sounds pretty damn neat. But my top priority is quality being outputted into the sub/amp. they are all between 1000-1250euro, x4000, x4100w, SR7008, and it's a present so, I could swing whichever, you know?
So far I'm more inclined to go with the x4100w, the bluetooth&wifi would make things very easy... Like, when my parents guests arrive they could just hook up to it via wifi and play their music or whatever.
Thanks for the advice guys. I'll wait a few more days to see if maybe somebody had the chance to compare the receivers(though, I highly doubt it, but then again, who knows) - and then if things stand as they are I'll go with the x4100w
