Video: noise floor and tweeter hiss, what do you think?

Thanks for the link to the article @russ69 

My speakers are 94dB sensitivity. Combined with 49dB gain may very well be responsible for the hiss.

I do us a Puritan mains filter and good cabling, so I do not suspect the problem lies there.

Hello Robert! I have a Nagra Classic pre, a Essence amp, high sensitivity speakers and I have hiss too :).

Of course I have more hiss if I turn on the 12db gais switch of the Nagra XD.

Did you fix your hiss?

thanks!!!

Hiss is normal and fine ! it's the signal to noise ratio!  that number is a better indicator if one is worried and  if nothing is reaching the chair your golden.

@ramon74 turns out there’s nothing to fix. I can’t hear it at the listening position so it’s not an issue. It’s normal, even in ultra high-end equipment. 

Thank you, 😁
