NCx252MP to leave on 24/7 or not?

[nonsubscriber]

I am guessing there is no 100% answer on this just opinions.

Vendor says for maximum lifespan the amps should be powered down when not in use. I always thought the opposite to be true re: heat/cool/power inrush factors. BTW these are quite warm to the touch when not in use.

Opinions welcome, thanks!

Definitely turn off when not in use. Heat is the chief enemy of the longevity of electronic components.

Absolutely do not leave it running. I burned one out this way after a little over a year (honestly, I did not realize there was also a mains switch in the back of mine - it was in a cabinet) and they are unrepairable! Sounds great but yeah. Trying to figure out my next move.

Definitely switch it off (not standby) and also disconnect it from the power grid.

Normal amplifier temperatures (35-45°C) are not a problem; amplifiers from the 80s and 90s prove this, as they still function perfectly after 30 years even at internal temperatures of 45-50°C.

However, the high switching frequencies of switched-mode power supplies and Class D amplifiers cause capacitors to age much faster. In contrast to conventional amplifiers and transformer power supplies, operating time can also influence the lifespan. The devices should be used regularly and not left switched off for weeks or even months.

I try to use 12v trigger wherever / whenever I can. You could also use it with a smart switch so let's say you turn off your preamp , amp will auto shut off. Hard AC cycling is not a big issue with modern amps.

When was frequent switching on and off ever a problem, except for the switch?

I was thinking more about hot restarts and shutdown behavior like speaker thump when older amps powered back on via switch.

Transients have always been - and will always be - a problem for some electronic components, like heat is a problem for some others.
But since chem caps are still the weakest point of these electronics, better switch off than keep on. Not to mention the disputable idea of consuming energy for nothing.

Assuming 20W idle, 24/7 on is 175 kWh per year, and 70kg CO² over here. That's disregarding producing and shipping the new device that you'd need a few years earlier.

Not nothing. Wasteful for convenience, or rather: laziness. You builders usually include trigger for a reason.

If you have to turn it completely off and physically disconnect it from the grid you shouldn't have wasted money buying it.
