The benifit of the seperate amp is the power supply.Usually a seperate amp will have a more robust power supply than a reciever will.This means when you get the urge to really get to cranking up you music you will not run the risk of clipping the amp ie running out of power.As far as connecting the preamp and amp all you do is connect the pre to the amp using a pair of interconnects.The H/K is a pretty sweet unit if you are looking to keep the costs down.There is certainly nothing wrong with it.
