Unless you’re running fiber from your ‘box’ to ps audio streamer, you’re still susceptible to noise. In your setup, your router is a potential source of noise. Are you using a wall wart (another source of noise) or linear power supply to power the router? As suggested by @antigrunge2, use a network isolator ahead of PS Audio. Listen, access and share your thoughts.
the question of changing ethernet cables
Hi everyone, I am also new to the site and I have followed many conversations learning much. I have ethernet cables running from the router to the streamer (PS Audio). However, I have a fiberglass cable running from the street input to my main box. That should mean from what I have followed here that I am not bringing any noise into the system from outside. I too, have thought about changing the internal cables and/or employing an isolator of sorts. However, in my case, I am not sure that I need to. Any suggestions would be welcome.

“I have just the amp and preamp on I have a very slight hiss” I suspect that white noise / hiss your hearing is coming from router. Without knowing every single component in your system, we can only speculate. I used to own a tube amp that produced a very faint hiss, I could easily hear it when I am near my tweeter but otherwise inaudible few feet away. As you said, hiss is already there when you turn on amp/pre. The noise is further amplified when you turn on streamer. I would look at each and every step in your signal chain i.e. interconnects, speakers cables including LAN cable. Before you drive yourself crazy and spend more money, do you know if your electronics are supposed to be dead quiet? Contact the manufacturer or read other users feedback. Are you using a power conditioner in your system? The most common reasons for hiss is poor grounding or gain stage in your preamp. It could be also from poor wiring or EMI/RFI in your environment. |
