Leave it on?

Ok @gano I leave you with your opinions and conclusions. Enjoy your music! 

I keep SS gear on all the time unless on vacation or a storm.  
 

How long will you keep your new gear? 1 to 20 years as I am an audiophile 🤓.  Just don’t know. 
How do you feel about global warming? Really not a thing you know.  Current thinking is coming around to this thought. If you haven’t studied it, wait till you learn that we can’t even measure the Earth’s temperature accurately. Never have, never will. Our instruments, we humans, and our methods are flawed.  Always will be. 
How confident are you leaving other appliances on all day and night? Like my refrigerator? HVAC? Some lights? Water heater? I think you get the point. 
How would you feel if your house burnt down? Not good.  What does this have to do with the topic?  I think interjecting fear on this topic is not helpful. All of our homes have live 120 V outlets and electricity networked throughout the home. Fires do happen and that is certainly a possibility in most any home.   However, suggesting that leaving on a streamer, dac, power conditioner or amplifier  is more likely to cause a fire is really not serious.    
 

@mylogic I understand your point. I suppose life with our technology and conveniences comes with risk.   More risk than life before them some 100-150 years ago? Different risks for sure and obviously less overall.  I just don’t see the added risk of keeping your Class D amplifier on. Class A SS amps don’t all run hot today. Valvet is one example. I would not leave tube gear on 24/7. 

@gano, you are smart enough to realize a hot season, cold snap, or short term trend  is no way to draw long term conclusions…..unless one has an agenda. Brutal cold also kills today. Yes conditions have come together in Europe and that is real and unfortunate.   I am not saying it’s not real or a concern for folks dealing with it.  Don’t think leaving your amp or dac on helps cause either situation. 

For those of you that leave your gear on like dacs, streamers and SS amps I have a tip to try.   Every couple of weeks or so shut them down for 5-10 minutes and then restart. While I don’t understand why, I can say it did something positive to sound quality. A couple of designers I respect told me about this.  

Very true. Amplifiers also benefit sonically in my experience.  

I have a field  coil power supply for my speakers. I do keep it turned off.
