Davie6, welcome and congrats on your order, as I'm sure you are aware the M80's are 4ohm speakers, not sure of your model HK so I can't presume it will drive them.
Most of the mid end Denons, Yamahas and other name brands should have no issues driving the 80's. If you need to purchase a new reciever find one that has the bells and whistles you need. If you can give us a price range I'm sure you will get many suggestions.
