The Audeze presets on Roon are based on the legacy version of Audeze Reveal (just better because you’re using Roon’s superior DSP and have an additional linear filter). Audeze has moved on to their new version, which is called Reveal+ and is no longer free. And since it says on their website that the Audeze Reveal Legacy is supported for “2018 and older models” of Audeze headphones, I’d have to guess that Audeze would rather not mess with the Legacy version anymore and focus on the new version. See: https://www.audeze.com/products/reveal
I’m sure Audeze would wanna work on it as long as it gives them enough new Reveal+ sales. Personally, I’m willing to purchase a Audeze Reveal+ license if it will be fully supported with Roon, but I can’t speak for everyone.
