Leave an amp "on" permanetly

I guess how I was raised, taught me to turn things off when not in use. I do keep my cable box and/ or pre on, all the time.---I also think my CJ350 (ss), uses more juice than a 100 wt. bulb??--When I ran tubes (16 el34's) you know that was off when not in use.

Not sure I agree with "on" permanently. Most hi end hi-fi stuff will be tubes or SS amps that run mainly in Class A operationn.....these naturally run very hot and waste huge amounts of energy and besides, tubes have a limited life span...why would you want to shorten it further?

Today's New York Times has an article on how much energy is used by electronics devices that are left on vs. putting to sleep or turning off. Even if you choose to leave your audio components on 24/7, you may want to look at your practices with computer monitors, cpus, dvrs, and cable boxes. Here is the link:

When I bought my Kell, the tech lad at the factory said not to leave it on all the time. Of course try not to turn it on & off three or four times a day. 24 hours to stabalize sounds a bit exorbitant to me. I turn mine on, put on some tunes, do the dishes, feed the fish, do some chores, etc. With all the racket I am making who can tell the difference in sound quality? By the time I am done, she is ready & willing to do what she does best and post toasty at that.

Purely from an environmental standpoint, I would not leave my equipment on. I actually turn off the power strip to prevent the device from using stand-by power when it is supposedly off. I have a geology degree so I'm very familiar with the irreparable harm that we are doing to our planet. People who don't take such things into consideration are completely insensitive to the plight of future generations.
