Is slight hiss normal on Nac 82?

Hello, I recently purchased a NAC 82 with high cap. I was told the unit was recently serviced and has the pots 8 upgrade.

Firstly I am very happy with the sound, it is a very good match with my 250-2. My only complaint is a faint hiss coming out of the speakers. To most this may not even be audible but i am very particular. My listening room is also fairly small so its noticable. I have isolsted the hiss to the nac 82 as there is no change when I switch amps.

My question is, is this normal or can it be fixed? If this is a normal trait of the 82 is there another naim preamp that runs silent? I’d be willing to consider a nac 282 or possibly 252 if there is an improvement and no hiss.

Thanks in advance!

It’s normal and down to the high gain of Naim pre-amps. It shouldn’t be obtrusive though from the listening position, although it will spend somewhat on distance, speaker cabling, acoustics and how tipped up the HF response is on the speakers.

Mute the Nac 82 when you are not listening to music, then you have no hiss in the speakers.

Do you know if this “hiss" carried over to the 282 or was it just on tbe 82?

I’d expect it to be there on the NAC282.
