No of course not!
I’ve done some testing and I think the problem is that it’s all on the same table and very close. I tried putting the speakers on the floor and the noise fades a lot. I’ll get some speaker stands tomorrow.
Your laptop deserves a Fraim .
Try moving the phono stage away from the power supply.
I put the speakers on the stands and the thing seems better. But I ask you a question: is it normal that when you turn it on, without playing, regardless of the volume which at minimum or maximum does not change anything, when you put your ear close to the speaker, you hear a very slight hiss? Let me explain better: is it normal to hear that the NOVA is on? Or should it be totally silent as when turned off? If anyone can test it with their NOVA, putting their ear close to the speaker, they’d be doing me a favor. I’m getting paranoid
Hiss is perfectly normal, and is to be expected. Type ‘hiss’ into the search and be amazed.
There’s a Earth normal/floating switch on the back ,have you tried moving that
And not only for the Nova!
Yes, now it’s on normal
This comforts me, what I would like to exclude is a flaw in the Nova. I took it on Wednesday and yesterday I didn’t notice this. With Atom and Star I had a precedent I hadn’t noticed.
I can put my ear right up to the tweeter and there is no hiss whasoever with my Nova. However there is a very slight hum from the unit itself, its mechanical from the transformer and this seems to be the norm with Naim kit…Dont hear it unless i am right by the unit itself.
In the meantime I had reported the matter to the seller, luckily he is a dear friend. Last week he came to my house to check it out for himself. They tried both an Atom and a Star in the shop and they are perfectly silent, unlike my Nova. At this point I’m confused…
Still on guarantee, so you know the next step .
And your friend dealer can let you an Atom or Star during the wait.
Bear in mind that you are more likely to hear hiss if you have more sensitive speakers.
The move has a bigger amp so may produce more hiss? Both my nova and supernait 3 hissed through insensitive atc speakers , it’s all perfectly normal for naim… on the other hand my atc amp is very close to silent.
Today I went to the dealer, I tried to listen to a Naim Atom with speakers like mine and there is a slight hiss coming from the tweeter. Then I went home, listened to mine and here it’s different. Here you can hear a hum coming from the subwoofer, while from the tweater you can hear the same light hiss that I heard in the shop. I have a video taken with an iPhone in front of the subwoofer, if you turn up the volume you should hear the hum, but I can’t upload on forum due the format not allowed.
Just for comparison my Atom is silent with nothing playing. I have returned one previously with a hum coming from the unit itself.
I took my Atom to the dealer. It is silent from them. Then I had the Star I previously had returned and tried it again at home. It’s silent. The Atom is probably more powerful and there is something in the home network that disturbs it. They gave me longer speaker cables, 5 meters long, and the hum subsided but didn’t disappear. Tomorrow I’ll try some ferrite rings on speaker cables. Otherwise I don’t know what to do anymore.
Any update Tony?
So, with the 5 m speaker cables and the ferrite rings it improved, then last week I bought the DC Block from Audiolab and it improved further. The speakers are almost completely silent, just a very slight hiss, but that is normal.
