New Nait 5si owner - questions

Posted by: Frankienfld on 27 January 2016

Bought my first naim component yesterday.   So far utterly enthralled with the sound.  A few questions though:

Is the unit intended to left powered on at all times? I gather this from the location of the switch and the obvious labour on the unit during power up/down.  

When the volume is turned up to 1 or 2 o'clock there is a light audible high frequency buzzing sound. Is this normal? I'm sure some improvements to my AC feed could help this, and in any event this doesn't affect listening levels.

The remote appears useful only as a volume control - you can't switch inputs with it   Am I missing something?

thanks for reading!

Leaving on all the time is fine, and recommended. High frequency buzzing sound at 1 or 2 o'clock, that will be your speakers about to blow their tweeters across the room.

Ha - indeed - of course I mean without playing any music!

Ok.... Good. I'd expect a slight buzz through the speaker at that setting, perfectly normal.

  1. Leave it on, and use MUTE when not listening to music
  2. humming is normal - that's what NAIMs are like. But... if it is too loud, ou may have a geound loop problem
  3. To switch inputs via a remote control:
    1. Press a grey button labeled PRE
    2. Presss no 1 for CD, number 2 for Tuner etc etc.

Hi,

I run a Nait 5 si and have done for two years into Credos.

Two things I would like to point out :

1. There is no Mute button.

2. You should not be getting any hum whatsoever that is coming from the speakers at any volume through any input with nothing playing.

Mine does not hum with the volume full on nor does it hardly HISS unlike the amps of old.

A very quiet amp if you ask me. (in terms of noise)

So, maybe you have an earth problem or badly routed cables?

Thanks Stephen.  There's a mute button on my remote (and magically the remote for my Marantz cd6005 also controls this amp, with no programming). 

Re: The hum, funny enough when I plugged in another analogue component to the Nait, the hum disappeared and now it is dead silent.   Must have been some kind of grounding issue.
