It's more about general mass market consumption I think. Those of us into this stuff will usually buy appropriately I think. Those that lightly research or don't understand how to put things together (like an avr/amp with appropriate speakers to drive to the levels needed). My oldest avr is from 2004 but still around and put to some use here and there. My next oldest is from 2007 (the avr itself, I bought it a couple years ago for my workshop system),then 2011, then 2012. All in use in various systems mind you, some purchased for expansion of capabilities as well as additional rooms. I did have a Pioneer fail in the middle there. Are they the most durable units these days what with the problems hdmi/video can bring on outside basic audio functions? Surely not, but they still are good tools for the jobs I need them for. I do have some separates, but they're 2ch...it just didn't seem to make sense to go into the av area like I did with a full on pre-pro/amp and I think I made the right decision myself.
