NAP 135

Posted by: David O'Higgins on 28 August 2001

I have just bought a pair of 1998 135's and I got no sleep last night. This pair has been out of service for a while, so they'll take some time to warm up but I am really enjoying the music.

My question is whether to leave them permanently powered up ? What are the +/- ?

I don't have 135's, just a 160.

However, I switch my power amp off every night but I leave the pre-amp on. The system sounds good immediately when powered on again next day.

Yes, leave them powered up. This is Naim's view too, IIRC its in the manual.

The 135 to my ears takes over a week to really give what it is capable of, and goes through a pretty obvious warm up cycle. When I had a pair of 135s I could tell whether my landlord had been messing with the mains power as they sounded "off" after an outage. Bigger the PSU the more obvious the effect, though by saying that my little Nait 2 is sounding better than ever now its been cooking for a few days.

leave 'em on. You don't unplug yer fridge each night, do you? You'll notice a gradual improvement up until about 2 weeks into it, as a bonus. And then theres the thermal stress of repeated cycling.... leave em on. Just don't forget to mute it when not in use.

Rico - ok, the Kans are sorted, now whatabout the rainforests?

I leave all my gear including the 135s powered up all the time... the electricity consumption is so small that you need not be worried about the cost and you will know that the system is ready to give of its best...mains supply willing.. immediately.

All naim gear is designed to be left on 24 hours a day, every day of the year.

There are only two reasons for switching it off every evening.

1. Cost of electricity.......I suspect that the cost of power consumed by a Naim system is less than that of running your electric tootbrush. In other words, its so small, its unidentifable.

2. Lightening......you have more chance of winning the Lotterey than having your system hit by lightening. Anyway, its covered on insurance.

By switching your system off/on everyday, you are in the ludicrous position of spending thousands on a top notch system and obtaining only some of its sonic benefits in order to save pennies.

Also, according to Naim's service dept, the cost of replacing the on/off switch is more than the cost of electricity saved.

Leave it on all of the time.

I would recommend that you both switch off and unplug your system from the mains during a lightening storm. Your system can fried by a hit on the electricity transmission system (which aren't uncommon), the hi-fi's own power switch is unlikely to insolate this kind of surge. Having said that in Dublin, big lightening storms are few and far between.

Otherwise I agree, leave the 135s on all the time, they sound much better for it.

Everyone

I get the picture ok.

Specifically for Mick. You gave 2 reasons for switching off. Neither of these are why I switch my 160 off. I've never given a thought to how much the electricity costs if leaving it on and I don't worry about lightning strikes either. Now that I think about it I don't know why I switch it off, I've just always switched it off and have never noticed the system sounding worse when I first switch it on next morning. Had I noticed that the system sounded worse I would leave it on all the time as everybody else seems to do. smile
