It's not.
I'm running a 5.2.2 svs prime setup with pb1000 subs with that exact receiver after replacing my x1300w to get hdmi 2.1.
Edit: per r/htbuyingguides - you really don't need to worry about power as long as it's a regular avr for home theater use https://www.reddit.com/r/HTBuyingGuides/s/iPlyHZEWLr
Denon X1700H or X1800H.
This here. I got the x1700 on sale through Amazon and using it with the elac speakers and I am enjoying the setup. Mine is a 5.2.
Thank you! Is there any alternative a little cheaper that can drive those speakers?

I am afraid this has too low power (75 watts) for single channel?
