Anyone compare Ayre Codex to QB-9 Twenty?

Not sure if the QB-9 Twenty would be worthwhile upgrade over the Codex or not. Many said the Codex beat the original QB-9.

Thanks,

I got the QB-9 around 2015 and upgraded around 2020. Well worth it. The QB-9 20 gets use every day as a part of my headphone system.
