However I am not sure this would be true for their upper end models. I think anyone, no matter how wealthy, would get peeved if they spent money on the most expensive top of the line model and then had to change it after 2-3 years.
Of course this is just all conjecture.
There's little to go wrong with modern AVRs. If treated well, they are likely to last many years.
Not sure how the change in solder has affected AVRs.
Premature failures seem somewhat common with a few brands. Not sure if it's owner abused or not.
Adequate ventilation seems like a good idea, as well as not pushing your receiver to it's limits. The amount of heat in some AVRs is very high. It's possible even with good ventilation some receivers may fail earlier than others due to that factor.
