The reliability of a system such as an AVR is calculated by the product of the reliability of each component required for the system to function properly.\nI am admittedly grossly over simplifying this, but if we say that an AVR has a signal path that involves 25 components and the reliability if each component (say lasting 5 years) is 99% we would calculate the system reliability (for that signal path) at 0.99 raised to the 25th power = 0.778, or we would expect 22.2% of AVR's to fail within those 5 years. And that is for just one signal path (keeping it simple)!\nObviously an AVR\/AVP (and especially this one) has more than 25 components that are critical to functioning and some of those components like a piece of wire have nearly 100% reliability (unless failure elsewhere results in an over-current condition, but the other failure already resulted in a system failure).\nHowever, 99% reliability for 5 years is not a given.\nIf we have 50 components (still way shy of your Denon) at 99% we would get 60.5% reliability for the system.\nThis is my effort at explaining why this incredibly complex unit seemed doomed to failure (disproportionate to a more typical AVR\/AVP).\n\n@KEW, your a Engineer? Audio? Electrical? Was just polking fun about the "Sausage" thing ;):p on that other thread. When I was in the oilfield and a Engineer in petroleum would come on deck some had a sense of humor some didn't. Anyways if you still mad or not here's Mud in ya eye!:p;) get it? We had a lot of "Mud" Engineers in the Petroleum industry. Oh and the next time you post up I'm "Worthless" or was it "Useless" look out! I have a bunch of minions that'll follow you for the rest if your days on this Planet!:p;) Have a good one KEW.
