If you want th best for what you are willing to spend, it really seems like the next big update will be to HDMI spec in the 2020 release cycle... so maybe if you can play the long game and wait 2 years, you get the discounted price starting Summer 2021 for something that then should easily (*knocks on wood) cover several years of upcoming releases.
I have accepted this as my path... new HDMI protocol as well as stabilization to the multi-channel receiver market. *fingers crossed
It will, of course, not be this simple. However, in my mind: I will be able to get a 16-channel AVR with a seven channel, fully assignable amp, Dirac Live with Bass Management Module, and a Rootbeer Lollipop. All for $1995, MSRP. Marked down to $1249 the following summer!
