Anyone using MM7055 with 4 ohm Speakers?

Just curious if anyone is using a Marantz mm7055 with 4 ohm speakers and having success with the amp. I talked to Marantz support and they did tell me that the amp would eventually blow if I ran anything with 4 ohms off this thing. :(

I am running monitor audio rx8s which are 4 ohms, gxc150 at 8 ohm, and rx1 which are 6 ohm.

Thanks in advance for any advice.
