Warmup
Posted by: ursus262 on 09 June 2016
I was wondering what people's opinions are about switching off our naim systems when not needed and how long they need to warm up again.
We switch off our entire system at bedtime and before going out to save energy. How long does it take, do you think, for the system to properly warm up again?

Noooooooo...
The search facility will throw up more posts on this than you have time to read.
Leave it on.

Warmup time? A few hours to a few days, depending on what kit and what environmental conditions exist. So chances are you've never heard the full capability of your system, Dave.
Have you worked out how much you're saving in energy costs... and does it exceed the repair cost associated with the probability of component failure brought about by continued power cycling, intangible though they may seem?
I suggest you re-evaluate your reasons for choosing Naim in the first place... if they were to do with residual £values, carry on as you are, but if they were to do with sound quality you should revisit your energy strategy... I did... mine's on now and I'm not listening to it ![]()

Mine only gets switched off when there is a thunder storm or when I go away on holiday

I've heard say you should move your kit OUTSIDE during a thunderstorm in case lightening strikes the house and everything INSIDE gets fried. Luckily we don't have that many lightening strikes on the Wirral (near Liverpool), so I usually risk it and leave it all indoors when it thunders.
ursus262,
You should tell us what system you've got. I don't think warm up time for Naim gear is necessarily patent across the board. On the other hand, on-off cycles may be a more important consideration for any Naim gear.
I think the consensus on this forum is to leave your gear on all the time.

Same which seems to be the same on the forum
Leave it on, if you want to save energy listen in the dark.
I switch mine off for lightning storms and longer holidays. Takes about half day to get back to normal performance I think. First hour or so is very obviously 'off' to my ears.

Crikey! I've been doing it wrong all these years

Ok, I've decided. I'm going to keep it on 24/7. Just got to work on my partner to allow that. Wish me luck!
You'll just have to turn the heating down and wear a woolly jumper, though it can get a bit nippy in Todmorden.

You reckon?!
Water! It's the water we worry about! ![]()

Easy - tell your partner Naim is not designed to be switched off on regular basis. It will fail if you keep switching it off. If you have any of the streamers or CD players, back your point up by eloquently stating - that is why the power switch is at the back - it's for emergency only, not for regular use.
That should so the trick ![]()
Yeah, right lol ![]()
In summary: Leave your kit ON ALL THE TIME.
Change your savings strategy:
- Listen to music in the dark
- Use woolly clothing and turn off the heating in winter
- Be naked in summer and turn off the air conditioning
- Take the shower with your partner
- Eliminate sugar (also good for your health)
If you saved more than before buy upgrades for your Naim kit or buy more music. Enjoy.

Finally - a definite guide as to why Naim gear must be left on.
And.....return to answer 1.

Hi Roger,
you think component failure may 'be associated turning it off once a day? I turn off my Superuniti at night and turn it on when I wake up, when I get home from job at 6 pm should be ready. But if this can cause damage then I think about it.
What say Naim engineers about it?

The premise is that capacitor failure generally occurs at start-up and that successive on-off cycles increase the likelihood of failure. I think that most all engineers, not just Naim's, would agree.
low current devices pre amps .cdp etc leave on. power amps switch off is the most common sense approach for the safety of devices

Is it really? That's a new one....
Joerand, this is my experience too, however the capacitor's effective series resistance (ESR) tends to increase over time of use, and increased ESR reduces the capacitors efficiency and increases the power dissipated within the capacitor thereby increasing heating. This then tends to hasten the aging and ultimate failure of a capacitor.
Better quality capacitors tend to have published lower and more stable with respect to time ESR.
FWIW I leave my audio equipment, especially my amps, switched on, and initiate a power down / power up every month or so or when I am away for more than a few days.

What happens when a capacitor fails, poor quality sound or there is no sound?

I'm in Haydock and we had a thunderstorm this very day, sadly by the time I had turned my kit off and got it outside the damned thing had moved on. Tempted to just leave it outside in case it come back over night
