You're looking at two sources, but that's hardly the 'whole industry'. In order to say "supply has recovered", it has to happen everywhere and that hasn't happened. I just looked at the site of an electronics distributor that's part of a larger corporation that has been buying regional distributors, checking for AVR availability- they carry Denon, Marantz, Sony & Yamaha, showing 10, 7, 2 and 8 models, respectively. When I checked all four brands, most branches show 'Call for availability'- they have 13 locations that serve literally thousands of dealers. I didn't check with the parent company's website but I looked on another distributor's site that serves a smaller group of dealers and they have almost nothing in stock from Denon or Yamaha.
The supply shortage isn't over, by any stretch of the imagination.
