Is it ok to use the mains outlet switch?

Are you aware of the power-on, power-off sequencing? If not, you can find it here:

Also, when powering down for an electrical storm or for longer term (i.e., vacation) the gear must be unplugged from the mains to be protected from a power surge.

Hi Joe, many thanks for the link and the great advice. I am following the power up / power down sequence and will definitely unplug from the mains when away. I am just wondering if it is ok to use the mains outlet switch (on the wall) to power up / down each naim unit. It is just more convenient than having to reach at the back of the naim unit to find the switch. Just want to make sure this is will not cause any problem or (worse) damage.

Many thanks

According to the manual:

"Source components and power supplies should be switched on before the power amplifiers. Always switch amplifiers off and wait a minute before connecting or disconnecting any leads. Always use the power switch on the product rather than a mains outlet switch."

Not what you wanted to hear, but I presume Naim say this for a reason.

The 200's switch is on the front.  There is no switch on the back. Am I missing something?

The switch of the 200 is on the front but it is currently placed behind big table and other pieces of furniture so it is difficult to reach. The Naim Dac V1 next to it has the switch at the back. I would ideally like to be able to leave them there and use the mains outlet switch instead. 

Cheers

Many thanks for the heads up. It looks like I will have to rearrange furniture :-(. 

I guess there must be a reason for this guideline by Naim.

The amp should always be switched on last, after all the other units, and switched off first - this way you avoid any pops from other equipment being switched on being amplified through the speakers.  I suppose if you're adamant to use the socket switch you could use a double switched socket - have the amp on one switch and everything else on the other.  You will need to remember which is which though, otherwise....  And if the fuses in the equipment keep blowing then you may know the reason behind Naim's recommendation.

But then, of course, Naim kit likes being left switched on all the time, so I guess you won't be switching on and off very often.  Or you could do like I do with the main music room system; I leave everything powered up barring the power amp. Half an hour or so before I want to sit down and listen to some music, I switch on the power amp.

Probably better to re-arrange the furniture...

Many thanks Richard. Much appreciated advice :-)

Now THAT'S an interesting suggestion Richard.  Ever since my house was struck by lightning and my amp and speakers were nuked some years ago I have been very uncomfortable with the Naim advice to leave the system powered up.  So I have been switching everything off and then trying to switch on ahead of time to at least get everything warmed up.  Just switching off the power amp seems brilliantly obvious now you suggest it.  Why didn't I think of that before?  Duh!

Your other gear is at least as likely to be damaged by lightning as a power amp. Anything connected to a phone line or aerial is at greater risk, as these are exposed to lightning, so servers, streamers, tuners and TVs are vulnerable.

Possibly because you don't understand the difference between switching off gear and disconnecting your system from the mains or other electric conduit.

Forbarry, as Joe implies in his post above, just switching off at the mains outlet is unlikely to protect you from a lightning strike - you need to ensure everything is physically unplugged - including any aerial connections.  And that's before we even consider induction effects...

Any reason you don't leave the amp powered up too Richard?

Yes Steve.  We tend to get quite a few power outs here in the country - usually just short ones.  Our mains comes in from the main road via the old three phase exposed copper cables and runs right along the edge of a wood.  When the wind blows, the tree branches act on the cables like a fork to spaghetti and the lights in our house flicker away until the inevitable happens.  Anyway, I switch off the power amp just to ensure that should the worst happen then I won't find the drivers from my SL2s spat across the room.  It's unlikely but better safe than sorry...
