I've read the audioholics review, but from reports on other forums I don't think the 4ohm dip is much to worry about, and any decent receiver can handle these speakers, remember they are also very efficient and don't need much power to play loud, I would not let power be a major consideration.
There are some nice deals to be had on ac4l.com for receivers, most of them are last years models though, so not sure about HDCP 2.2 support.
Your setup looks great, the only suggestion I have is to use a P163 placed vertically as center channel, it is much cheaper and will be better sonically but may not look as nice.
