Hi guys, I bought Marantz 6006 to go with my M80. The sound is great, however even if I go nominally loud, the receiver shuts down, the blinking red light means that I am using wrongly rated speakers, which is correct, M80 are 4 ohm and Marantz does not want anything lower than 6.

I really love the sound, better than couple of yamaha and denon I have heard, but unfortunately I can't do with the receiver shutting down.

What would you guys recommend, how is Onkyo NR809? Any other receivers that are 4 ohm stable?

Any advice will be much apreciated.
