NAD has a couple units that have Dirac onboard. Been using a 777 for 4 years or so no issues. I like it and find it to be entirely customizable for my setup. Audiosciencereview panned it….. but I have zero issues with it in real world use. The T778 is its replacement I believe

I had and Arcam AVR360 for 7 or so years as my main AVR and still use to this day to drive my ceiling height channels. No issues. I did find Arcam to be pricey for what you get and dealer/firmware support a little lacking.
