Leave it on?

@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. 

 wait till you learn that we can’t even measure the Earth’s temperature accurately

maybe unlivable and deadly hot in Europe right now is not accurate for you, but counting the number of dead is a precise number

@grannyring ”conveniences come with risks”

I note your points, thank you. No offence intended.

@gano The Hots

l just came back from Lanzarote and it was hotter in England. Most Americans think of England being rain and green fields. Parts of the UK are officially becoming drought areas.

People are flying out to Continental Europe seeking the heat and Sun. The mind boggles. It’s turning into an upside down World

I use SS gear and I leave it on 24/7, because I listen daily. Simply sounds better to me after a long burn in (no pun intended). Never had a failure in 60 years for leaving ss gear on. In fact, I keep an FM station playing 24/7, through the system, except when I listen to something else. Enjoy! MrD.
