Coincidentally, the AVR market will be 2.8 billion USD in 2028. I doubt the market for DAC’s will be that big.
Currently, sales for AV receivers are said to be around $2.2 billion.
What they don't realize is that this statistic also includes all cheap AV complete systems/home entertainment with amplifiers from LG, Harman Kardon, Sony, Yamaha, Inkel Corporation, Pyle etc., which are sold by the millions.
Take a look at electronics discounters, there are 10-20 of these systems on a "real" AV receiver.
In addition, there are all the very cheap and also pseudo AV receivers from Auna, Pyle, Inkel Corporation and many others, which are sold in some countries for as little as $100 and in unbelievable quantities.
If the type of AV receivers we are talking about here on the forum and in this thread account for 25% of the above sales, then that should be a lot.
