Leave it on?

@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. 

I have a Carver 5X100w amplifier hooked to my Rotel Surround pre-amplifier. I turn on and off the Rotel - it does that with the TV remote, but the carver stays on all the time. Every once in a while I'll turn it off, but for the most part it's always on. This thing is over 30 years old and quiet as a mouse. That is my surround system, not what I listen to music on. My stereo is all tube except the streamer and the Schiit Loki Max - which I never turn off.

right, I am drawing conclusions from the past 50 years. During which the climate on the Planet changed dramatically. The place where I grew up, when I was a kid, 85 degrees was big news and people talked it for a week, is now 100+ for weeks and months. Not once in a while but EVERY SINGLE summer in the last decade getting hotter every year.

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.  

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