Suboptimal gain structure FTW. Somebody has some pro audio experience and a good mentor. I had both and the two key lessons I learned about signal chain were grounding (hum) and gain structure (noise and headroom). And both are seriously ignored in most hifi systems. If either are problematic in your system, the fix is to properly set your system up, not shop for new pieces that happen to match your system needs.
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.

Interesting post for me. I just added two Parasound A21+ amplifiers to my system and am having the same hiss at close proximity to the speakers (2-3 inches) with no source material playing. When I installed the amps I didn't have any sound coming through from my sources and no hiss either. Spent two or three hours trying to figure out what I did wrong, As a last resort I turned the pre's volume all the way up and got a faint signal, so I turned the gain up on the amplifiers channels to give me reasonable volume. I've never had amps with adjustable gain before and it would never occur to me that turning it up too much might have started the hiss. I have some headroom for the levels that I listen at, so I will try turning the gain down a little and see what happens. BTW - I had been using Holmz #2 suggestion. It works. Thanks - Jim S. |
