Those monitor audio Silver 8 will drop down to pretty low impedance in some areas of the bass/midbass. If you wanted a different receiver, try to get the biggest heaviest receiver possible. Maybe used if it's in your price range, like a used Yamaha RX-A3060 or something. Denon has large receivers as well.
Ultimately, you might be better getting a dedicated amp with a big power supply to drive those Monitor Audio. It's going to perform much better than any receiver. Maybe Emotiva if your budget is low. Or look into an Odysse Audio amp.
