I've got a Harman Kardon, it kicks serious ass. before you get something else have a look, my mate spent 4k on a denon and it isn't as good as my $1600 HK, instead of having an~20amp tranny for the entire amp rated at high wattage, its got a dedicated speaker tranny that outputs 50amps which is just for the speakers. its rated at 75w rms for all channels but it is amazing, when you crank it you can feel the sounds instead of just hearing them and then having it hurt you're ears when.
