How noisy is my line? Audio Prism Noise Sniffer


A friend and audio journalist had this Prism device, and he plugged it into various outlets when I visited him. It gave a clear sense of which outlets were noisy and how effectively his conditioners were helping with noise.

 

He said these were not made any longer. Does anyone know of another tool like this?

It seems like it could save someone with clean power (or a quiet outlet) a lot of money from conditioners/regenerators which would not necessarily help.

@thecarpathian Yes, I'm still very impressed and satisfied with the Ascend ELX towers. They are the equal of a bunch of other speakers I've heard -- to my tastes -- including Wilson, YG, and others. Their synergy with my Quicksilver mono 60s and Pass XA is excellent. I'm still wishing I had kept the Fritz Carbon 7's but that may be a second speaker at some point.

I saw the meter reading and demodulated noise from the meter speaker on a dedicated line running from a very expensive dedicated subpanel.  There was still, somewhat high level of noise, that was substantially reduced by a powerline conditioner.  The system had no audible noise, as such, without conditioning, but the sound did improve with conditioning—particularly with respect to creating a soundstage that seemed to float in space.  The meter being used was an Isotek meter, which is not cheap (about $1,000), but, $100 meters seem to work the same way.
