Well, I guess that depends on how you coach the question!
If we took a poll of "how many would prefer that their AVR be designed to fail after around 10 years?"
I think most everyone would agree that is a travesty!
But if we gave people the option to get a 50% discount by choosing a 10 year AVR (instead of 20), I think almost everyone would prefer to use the money saved to be able to buy an updated unit after the 10 years is up.
Of course, I made up the 50% discount. But it makes a point that we are generally willing to accept it if the price is right! I have no idea how much is saved by using a design life of 10 years. I do believe it would be incredibly difficult to design and manufacture an AVR with any real assurance that it would last 20 years (maybe impossible?)! I bet the best effort at this would cost well over 2X a 10 year unit. I'd guess 15 years might be the average for a modern AVR (with complex processing like Auddysey, Atmos, etc) if they chose not to go with 10 years! They are just very, very complex devices!
I might imagine that Anthem is not quite so far on-board the planned obsolescence train as the bigger players, but that is why I am not willing to afford them. I, personally, consider an AVR (if I will use it as an AVR and not just a stereo receiver) as something I would replace (or re-purpose) every 8-10 years. I guess that makes me an accomplice to your "pure evil"!
Does Bryston make an AVR with their warranty?
