AVR's will be tough from any supplier.

Why?

Well, several things. Last year, Sound United (parent of Denon/Marantz) announced they were buying Onkyo. Onkyo includes Integra, Pioneer, Pioneer Elite and Teac. Deal fell through for some reason, but not until Onkyo had adjusted production of products down, assuming that Sound United would take over that aspect at a specified time.

The deal fell through, and Onkyo + others did not have enough stuff coming in. Then Chinese New Year/Covid hits. So all of a sudden more demand then anticipated for other brands, and parts availability is tough.

So AVR's will be difficult from most brands as a result. Best advice: get paid for product and order immediately. Let customer know of time issues at time of proposal.
