Niagara 5000 Vs Torus RM20 or PS Audio Power Plant 12

After upgrading my power cords, speaker wire, and adding a USB Reclocker, my system has become more highly resolving and I’ve become extremely sensitive to fluctuations in the quality of power.  After midnight, my system becomes insanely revealing, holographic, and unconstrained.  During the day, not so much.  I am wanting my system to sound like it does after midnight, all the time!  

My dealer loaned me their Niagara 5000, along with an older NRG-1000 20A cord to power it.  Remember I’m using a Dragon high current to my amp.

Results - love what it does to bass and overall drive, but compared to that “after midnight” totally unconstrained free-flowing sound with my amp plugged into the wall, with the Niagara 5000 powered by the old NRG-1000 cord, I found the mids and upper frequencies to be constrained.  Not terrible, but not like that glorious sound I get late at night.

I’m thinking / hoping that if I were to power the Niagara 5000 with a Dragon High Current, then maybe the mids and uppers won’t be so constrained?  Any thoughts on this?  The NRG-1000 is a far lower end cord vs the Dragon.

Also wondering how a Torus RM 20 or a PS Audio Power Plant 20 would compare. Not sure if I would be able to demo either of these however…




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. 

@audioquest4life , I recently demoed the Sigma V2 NR and the Omega QR and commented in another thread. I found the Sigma to be slightly harsh in the upper mids, but only noticeable after extended listening. The sigmas were very “detail forward”. However, the Sigma demo had a 20-to-15A adapter as Shunyata didn’t have any 15A demo’s on hand, so I do wonder if that had a negative impact.

The Omega QR surprised me as it had a totally different presentation - buttery smooth, more refined, slightly warm, but still with all the detail.

Ultimately went with Audioquest Dragon HC not because I thought it sounded better (was more energetic/lively than the Omega - not better or worse, just different). But rather, because the Omega came with a yellow plastic tab to try to make the connection with my amplifier tight. It didn’t make a secure connection, and I thought that was a bit cheesy with the yellow tab.

The Dragon on my system is maybe a bit more rock and roll with more energized rhythm and bass, and with more forward but smooth detail (not as bright as the Sigma was). The Omega QR might be better for jazz, etc. But both would be great sounding with any music.

Regarding the conditioning tech in the Omega QR, it is very basic I think. It was not that noticeable at all, and even Shunyata told me a 3X Sigma V2 NR with a Denali conditioner would beat 2 X Omega QR with no conditioner for my source equipment. If you only need mild conditioning maybe it would be fine.


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.
