equipment switched on

For god's sake don't mention gas!  Your liable to blow us all to kingdom come.

Mind you I know who is full of it! 

Hi Wat.

I am sure somebody here can run the system on bio gas/ hot air & bad breath !  ATB Peter

But it's so wasteful.

Have you leaned nothing?

And speaking of waste, who in their right mind would buy HiFi components which are not locally built and distributed. I do. I'm such a saint.

Just to bring some objective engineering principles to the discussion, the increased stress and premature aging through power cycling is proportional to the amount of activation energy and the degree of temperature change between inactive and quiescent states.

Some of the equations and principles i have found nicely summarised here in this white paper.

In short the more large and powerful the device and the warmer it gets in normal operation the more damaging in terms of premature aging power cycling becomes.

I keep telling my wife this.  But does she listen!

Chaps - life's too short. Switch it off, leave it on. Do whatever works for you, your lifestyle or your values and just enjoy the music.

i'm very depressed.

apparently cows (and other livestock) make a not insignificant contribution to Green House Gases (GHG).

Why am i depressed?

Well, from now on, i shall have to stop buying cows milk --and while i am at it , also stop eating lamb.

How sad... :-(

Lucky i have a Naim system to cheer me up and it is sounding bloody good right now...

enjoy

LOL James!

That was page 1, quite near the top.

Do try to keep up.

I think I may be starting to loose the plot so just to try and summarise where we are:

Sound quality issues:

1. If I leave my Naim equipment powered-up 24/7 it will sound better, or,

2. If I only power-up my Naim equipment just prior to use it won't sound as good, or

3. Either option doesn't make any difference to the sound quality.

Electrical issues:

1. Leaving my Naim equipment switched-on 24/7 will waste energy.

2. If I leave my Naim equipment powered-up it's life expectancy will be extended.

3. It's safer to switch-off electrical equipment when not in use.

Please feel free to comment if I've missed something or got it wrong.

And stay from motor vehicles, air and sea travel, don't walk in the street, avoid all exhaust fumes and any kind of alcohol. Don't stand up from a seated position without a safety harness. All meat is off the menu and whatever you do, avoid climbing or descending staircases. If your bowels are a bit stuck, for god's sake don't strain. But do buy lottery tickets.

There is no right or wrong answer. Although I can see why you would think otherwise.

Following the manufacturer's recommendations seems sensible. At least to me.

Ah yes. Great minds etc. 

Aw Jesus Harry,

This is exactly what Swami Pete has been banging on about ever since he was Pjl2 (or whatever?). Please don't encourage him, or George. Even Richard can't persude them to steer a sensible course wrt to switching Naim kit on/off.

Peter, George,

The sound quality difference between "24/7" v "straight from 1xday old cold" is like day v night, despite George's assertion to the contrary. The power used to keep the kit "on-song" ready and waiting to go is part of the "useful" energy use, not waste.

If you don't have a job or other activities in your life, OK, you could schedule swith-on at 16:00 for a listening session scheduled for 20:00 (say) then power down at 20:30 when its time for beddy-byes. But, if like one or two on this forum, you have a busy schedule that precludes an effective warm-up period, 24/7 is not waste and is the way to go with Naim.

IMHO of course.

Cheers

Don

Dear Don,

You were correct in stating "IMHO," but spoiled it with a strike through. You don't suppose that I'd run my two excellent Naim boxes and then cripple them for the lack of continuous power if it made any significant difference. And as it makes so little difference, then to consume power by not turning off would therefore be wasteful.

IMHO, of course

Simple logic, which I did state earlier.

As for jobs and so on, whatever does that have to do with the debate? I get in from work at five-ish as I live suitably close to my work and so the commute is not long, and listen to an hour of "PM at Five PM" on Radio Four, and then sometimes the Six O'clock News, and sometimes right through to the Archers. Music usually starts after 7 pm in any case, by which time I am fully ready for the pleasure it can afford once tea is out of the way ....

I used to leave the machine on for the 10 pm News on Radio Four, but have taken to using the Tivoli for this. Usually the Naim and ESLs go off at this time, unless there is some good broadcast on Radio Three for example. Or I am watching a DVD ...

ATB from George

For safety's sake in the UK it’s best not to switch off when not using the audio.

Most plug sockets tend to be very low down near the skirting board and can be a bit awkward to reach when stretching out behind the racks, would be easy to put your back out or slip a disc or slip up [on that allusive slippery CD disc left carelessly lying on the floor] and back your head on the wall. Think of all the time off work this would cause, lost wages and trips to the chiropractor for expensive treatment, and not to mention the embarrassment of explaining the bandages on ones head to neighbours work colleagues etc.

Be safe and sound at the ready by leaving it on 24/7 I say : )

Quite a lot...............

I leave for work at 07:15 and get back at c.20:00, in bed by 23:00 most nights.

Doesn't leave enough time for the kit to warm up in the evening, so it stays on 24/7 to sound at its best.

"weekends" (usually Tues & Wed in my case), i'm out playing golf or fell walking, so again, not much chance to get the kit properly warmed up. So it srays on 24/7

Cheers

Don

Dear Don,

I have considered that I should get a good clock to start the machines ready for use when I used to work unsocial hours. Because I have a reasonable commute, I leave the house at either ten past seven or ten past eight as a rule, though sometimes it is earlier. We try to manage the day so the end is shortly before five pm.

The kind of high quality clock-timer that starts industrial boilers and so forth.

Perhaps you could consider such an addition?

ATB from George

I power down my second system sometimes 

Me, all the time, as it's the only bloody way to get the Qute to see the rest of the network, after 24 hrs connected it gets 'bored' with being connected and craves the company of an IT specialist 

So I'm the one generating excess heat 

Dear George,

I think you should run that one past Peter, first.

Remote switching sounds totally unsafe to me.....power surges in an unoccupied property.......OmG.

Cheers

Don
