Speaker static/hiss?

I’m noticing a static/hissing sound from my speakers on all inputs and when the volume is all the way down. You really have to put your ears right up on the tweeter to even hear it. It’s not noticeable at all when the volume is tuned up just about 5-10%.

 

But I’d like to see if this is something I can rid myself of. 
 

‘’I’ve got two dedicated 20amp outlets with two Audioquest 20amp outlets. All of the source gear is plugged into a Furman SPR-20.
 

Not sure what else I could do.

Likely your amp.

A Discussion About Idle Hiss – Upscale Audio

Turn the gain down on your A21. The knobs are on the back.

I thought about the gain knob. I’ll give it a shot. 
 

any recommendations for the setting to get it right?

It's just circuit noise. Try the gain controls and whole you're at it, try the ground lift switch. Give it 5 mins to let it settle.

Hiss is not solved with a ground.


You need to

  1. Use a lower noise amp, or
  2. Avoid being on all fours with the ear up to the speaker.

I would choose #2.
