I have the same AVR… never had an issue with Dirac except it fails if I have my sub turned up too high. I’m really curious what’s causing yours to fail

Decware or Wellington if you’re not willing to wait… shrooms

Speakers and amp… buy a tube amp if you have high efficiency speakers

For everyone curious about what that looks like: https://share.icloud.com/photos/088snagFWAtHFBWnz8MhLl63A

I see La Scala in my future
