Niagara 5000 Vs Torus RM20 or PS Audio Power Plant 12

@nyev,

Yes, but those are technical measurements with some being out of the range of human hearing. Although measurable distortion readings, these readings may not be audible. I believe that if anyone has noticeable power fluctuations which impact the audio component negatively that power regeneration is a must, no matter the manufacturer. I agree bout the fan noise on the PS12…Get a used P10 or opt for the new P15 or  P20 f you want to go the PS audio route with no fan noise. 

To reduce AC distortion on the main lines use the Environmental Potential EP2050 surge, spike and line noise eliminator. This is an industrial originated product used in commercial industry, hospitals, server farms, large manufacturing facilities…it elIminates nasty line noise which degrade sensitive electronics over time. It’s about 1k. Your electrician can easily install into the electrical panel if you have two 120 volts slots free next to each other.

Agree with you on all points. Adding to the discussion regarding our ears and listening impressions with various devices. I bought a 1/2 dozen of Shunyata Sigma NR 2 power cables for my system. Well, too much is too much. I used Neotech hi-fi pure silver power cables on my amps. They are plugged into a PS20. Well, the Shunyata did not seem to have the life or zest that the Neotechs have when plugged to into my McIntosh MC2301s. I tried direct in wall and into the PS20, the connection to the PS20 always seemed better to me regardless of which cable I m using. The sigmas are on my field coil power supplies now. But, I might experiment with the Omegas with QRB technology which is supposed to eliminate the need for any conditioning. 
 

When I plugged the Neotechs back into the amps, I had that aha, there you are moment, the sound I was missing when I was using the Sigmas on the amps was back. So, I have discovered that as you said, our ears can become objective. 

@nyev,

Thanks for that feedback. Yes, that plastic adapter to make the plugs have a firm fit with the equipment sure looks and feels very, well, low grade and out of character for such an exotic power cable. You have now piqued my interest on your impressions of the Audioquest Dragon HC compared to the both the Omega and Sigma. My sentiments with regards to PCs sounding different, but good at the same time, is like creating an Italian spaghetti sauce at different restaurants. Most of the time the sauce is good, but definitely different tasting. Sometimes you do get some really bad tasting sauce, the same as experiencing bad PC synergy with one’s own system. At the end of the day, we are all trying to make our own special Italian sauce to our liking. Heading over to your other posts. Thanks for the information.
