I agree, I don't see much reason to upgrade. The current lineup can pass through 4k, dolby vision, etc, so there is nothing new on the market necessitating the need for an upgrade. You might hold off though, last summer they had a 20% off sale, for trading in an old AVR. Crutchfield honored it, but didn't require sending your old one in. Maybe they have another similar sale sometime.
