I was poking around on the internet for a Denon AVR-3805, and found lots
of them on ebay and ubid, that are refurbished.

Why are their so many refurbished units? Is there a problem with the
AVR-3805, that so many have to be sent back to the factory?

With the Yamaha RX-V1, which had misfiring protective cutoffs. It has become
increasingly common.

These units are so complex, they are prone to design mistakes that require
recalls.
Once recalled and serviced, they are good-as-new, but the manufacturers do
not wish to be threatened by lawsuits alleging misrepresentation of "used"
as "new." IMHO, it's an irrelevant distinction.
