Consumer audio is a choice- we can life without it. The electronics industry classifies AV and other entertainment as 'lifestyle' but audio systems that need to continue operating during a fire, like a PA that announces where exits and safe places are during a storm, fire, attack, etc are called 'life safety'. In those systems, the specs call for the amplifiers to continue operating up to and including the point of destruction. Lifestyle vs life safety are real categories in the electronics industry- among others, alarm and video surveillance systems, medical monitors, various detectors and anything else that will keep people safe are in the latter group.\n\nThere is no requirement that an AV system operate at its maximum for a long time, other than maybe what a user demands. The FTC or any other government agency don't require it, but some manufacturers still use long term application in their specs because system designers want to know what to expect. Most people don't operate their system at maximum and anyone who does, needs to make sure the SPL isn't so high that it will damage their hearing if they want to hold a conversation in their later years. .\n\n\nI see where you are coming from, however this gear is now a substantial hunk of change. The big issue as I see it, is this parameter more directly than you think speaks to reliability. If a unit is under stress, which with current specs, they will be. Then it points to short life. Too many receivers fail, and now with the increase in complexity costs have risen, but probably not as much as they should have. Reliability of receivers is not good enough, and few are happy with four ohm loads, which actually most loads are. So they are getting less and less fit for purpose. Failure of units north of 2K is a definite life style problem. This is also compounded by the fact that I understand you seldom get prompt, convenient and courteous service in the event of failure. Too often service is not even available under the excuse parts are not available, because the production run of critical ICs was not large enough.\n\nThis is another reason I'm so keen on active speakers, as the amps are driving one speaker frequency band, and there is none of this power sharing and sleight of hand. This is one of a number of reasons why failure in car audio systems is so rare, even though the operating environment is harsh. Car speaker systems I would point out, have been active for some time.\n\nSo I would encourage members to pony up the funds up front and go the pre\/pro route, with external amps, and as time passes encourage more and more to purchase active speakers. Then you can build life time systems and save a lot of money in the long run. We have huge denial here on how bad a bargain a receiver actually is.
