Reliabilty, Keeping Equipment Powered on or off?

I've previously noted that leaving things on even at the suggestion of amp designers is the domain of wasteful boneheads who, as an example of wasteful boneheadedness (!), might also leave their cars running at all times to insure proper engine lubrication without that pesky "start up" stress, and leave refrigerator doors open to obviate door hinge wear, etc. I've since completely changed my stance on this issue (although I turn my rig off so I don't have to think about it blowing up when I'm not listening to it) as the rampant wasteful tendencies of people have irretrievably set our demise in motion, so you might as well waste whatever energy you can. After all, your audio playback standards can make you happier, and will help assuage any stress from, for example, an area of African farm land the size of Alaska recently being rendered unusable from rising sea water contamination. Who cares? Get yer Mahler on and you can let the kids worry about all the other stuff...  

My REL subs are always on, but the standby power is so low as to be insignificant. The rest of my gear warms up (tube amp) and sounds great. The "right answer" is to turn everything off since the benefits described by ANY manufacturer are minimal, but, as I noted earlier, people have lost the climate change battle as India and China ramp up thousands of coal plants, overpopulation driven by ignorance is likely to remain unchecked, and audiophiles deserve to have as much fun as possible. They just do.

Uh…just had to leave town for 3 days due to unexpected family thing and uh…left everything on including my tube amp. Man...
