Humming and hissing supernait3

Hi-Fi Corner
1

Hi all, I just have two minor issues left on my supernait3.

When picking up something from the ground I noticed the tweeter of my floorstander was hissing only to be heard when your ear is next to the speaker. Only thing I connected to the SN3 is a Nait streamer and 2 optical cables from other devices. Hissing stays the same if I turn the volume up. It does not affect the music because that sounds great. Is this normal and if not solvable?

Second issue I will address in another topic.

Thanks for the help.

Yes, the hiss is perfectly normal and nothing whatsoever to be concerned about.

3

Completely normal transistor noise for naim as less components in output stage ie no relays

Thanks guys, then I will leave the hiss for what it is. Regards.

Hi, just to be sure I understand because my native language is not English. You mean that Naim uses as less components as possible in the output stage and this causes the hiss?

Yes- no muting relays . Most amps will make some noise to varying degrees

If the op has a hiss through his speakers when the amplifier is not muted, how would the lack of a muting relay cause the hiss? Just wondering.

8

The muting relays would be on the output? So no relay = hiss

I just checked and indeed when muted the hiss is gone. Glad that this causes no damage to the amp. I am just not used to this, have had many good amps but never experienced a hiss before.

Is there a chance you haven’t noticed before?

Check out some other systems when you can get an ear close enough, I think it’s quite common.

I agree. Never had an amp before that has no power of button. My Cambridge audio that I owned automatically shut down along with the streamer.
