I would wait.
Supply chain will loosen over time, but shipping is still a nightmare for most manufacturers. (I'm uncertain if these are assembled in Canada like their processor or not, but consider a lot of the component parts likely are coming from overseas.)
Yes, Their initial release Of the new gear was buggy and I have not heard anybody indicate that they have been straightened out.
Cost to performance, Anthem is also not usually top of the list. Perhaps Anthem Room Correction is better than Audyssey, but I get pretty good results using the XT32 App and wouldn't use Room Correction as a reason to go all in on a device that isn't fully baked. (Keep in mind, HDMI 2.1 upgrade is still pending for later this year if they are lucky.)
Regardless, this is a bad year to buy electronics. The HDMI thing is still very unsettled, supply is still a challenge, and most of the work on this years devices was finished under the pandemic chaos.
What are you specifically looking for in an AVR or AVP? What do you need in terms of features?
