Something can always go wrong no matter the brand. The receiver, any receiver, has no clue what ohm the speakers are. It is the resistance to the load of the receiver, the lower the ohm rating the less resistance.

If I were to spend that kind of money on a unit and it couldn't run a 4 ohm load I'd return it for a refund.
