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.

Pretty sure I don't need a sniffer to know that line power is dirty.  The power on the grid in my neighborhood is about 4% THD.  The output of my regenerator is .1% THD.

@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.
