LOL you are totally right.

My dad has a Sony receiver that he bought right when got back from Vietnam... around 1969 or 1970, and it works perfectly. It can also play ear-bleedingly loud, even though its rated for only 10 WPC i think. It sounds much better than his Sony receiver that is only a couple years old (and is being replaced with the AVR230 today )

Also, he has a Sony CD changer that he bought in the mid 90s right as CDs began to become mainstream, and it has had 0 issues. Same can be said for his tape deck which is about 25 years old. I've noticed that his older electronics tend to weigh a lot more too, i guess they were just built more ruggedly.
