Shunyata Sigma NR v2 power cord
The new Sigma NR v2 power cord is near the top of the line of the new Reference Series of NR power cords from Shunyata Research.
The new Reference Series power cords have all new VTX-Ag conductors, CopperCONN connectors, and Shunyata's latest NR noise-reduction technology that significantly reduces noise coming from the component's power supply and going back into the power distribution chain to potentially contaminate other componentry. They are primarily designed to be used for powering components in conjunction with a power distributor, but they can also be used to provide NR for components powered directly from the wall's AC receptacle, e.g. monoblocks or amps that are too far from the location of a central power distributor.
I've had the opportunity to beta test the new Sigma NR v2 power cord for the last few weeks prior to its release on April 3, and for the first application, I installed a single power cord to power my Denali 6000/S V2.
From the first moment I turned on the stereo using this power cord, I was...gobsmacked. I've heard some really good power cords in the last 10 years, but in all honesty, I've never heard a single power cord not only bring such a DEGREE of improvement, but also NATURE of improvement, as well.
The new Sigma NR v2 PC brings the type and nature of presentation that I've only experienced from Shunyata devices that have the QR/BB technology. If you've never experienced what a Triton V3, Typhon QR, Denali, etc. brings to the equation, all I can say is that the classic audiophile terminology we've used for the last 40 years simply does not apply any more. Put quite simply, you have to experience it to "get it".
Most of my experiences with great power cords to this point have resulted in a notable reduction in noise, hash, grunge and a concomitant increase in dynamics, slam, ability to scale incredibly quickly without "compression" and resultant improvements in transparency and resolution. Over the years, I've come to the conclusion that power cords are the most important cables in a high-end system for this reason, and, along with the power distributor, should be the first key purchases of a stereo system to provide clean, quiet, and un-restricted power rather than the final "tweak" of a stereo system. You don't build a superb house on a weak foundation, you build it on the best foundation you can for sound (no pun intended) engineering reasons, and the power distribution of a high-end audio system is no different.
But coming back to the Sigma NR v2....
The first time I head this power cord it was immediately apparent that all the adjectives used in audio reviews for this type of product don't apply. The performance and qualities this power cord brings require a new vocabulary as as well as a new perspective because the nature of the presentation is so fundamentally changed.
If there was just one word I was limited to for describing what the Shunyata NR v2 brings its...Verisimilitude.
Def: Verisimilitude – the appearance of being true or real.
There is realness and authencity that this power cord brings that, quite simply, I've never experienced before. Yes, its got all those audiophile adjectives I've referenced above: notable reduction in noise, hash, grunge and a concomitant increase in dynamics, slam, ability to scale incredibly quickly...yadda, yadda. Yep, its got all that stuff in spades.
But, it has other, more compelling attributes, as well. The Sigma NR v2 provides a very 3D-like simulacrum of the musical presentation that is the most holographic, dimensional, pin-point precise I've experienced. While its sounds amazing on all types of content, on full-scale classical symphonic music, you can really hear what the Sigma NR v2 can do.
Listening to Pepe Romero's classical guitar on Rodrigo's Concerto de Aranjuez by Romero and the Academy of St Martin in the Fields, you can hear the thickness of the spruce top of Romero's guitar. Moreover, you can clearly hear the individual notes, and the subtlety of the notes he is playing completely clearly and fully resolved even with the complexity and scale the full orchestra is going flat-out during a very dynamic passage. You can actually "zero in" with your hearing to every single instrument in the orchestra, and hear what that specific musician is playing within the context of the symphony overall. Normally, during these types of passages, these small and "intricate" details get lost against the background of the entire symphony playing en-masse. Not with the Sigma NR v2.
The Sigma NR v2 provides a type of "resolution" that quite simply, I've not experienced before. The orchestra can swing incredibly quickly and forcefully from soft to loud and you can still pointpoint and hear "into" each individual musician or instrumental voice. On Midnight Blue, I can hear the secondary reflection of Kenny Burrell's guitar, which is miked on the left, splay off the far right wall in the recording studio, for example.
The imaging is also notably improved as well, each musician or instrument being more focused, "palpable'..there's more "meat on the bones" of each instrument, more texture, more timbral accuracy and timbral nuance.
I could go on and on, but to conclude, there is so much more focus, ambiance, rightness to the presentation that it moves from clean, fast and technical (there's all that, those audiophile attributes, to be sure, but much more) to such a natural and "organic" quality that it sounds as if you are in the room with the musicians as they create the music that instant. Analogies again fail here but if I had to make them its like going from an Apple iTunes track to listening to the recording's orignal master tapes set up by Alan Yoshida and played back on a world-class Studer reel-to-reel tape deck. Or like looking at a JPEG from a good APS-C camera to a 16-bit TIFF file from a 100 megapixel Fuji GFX100 medium-format camera in Capture One Pro 20.
Really extraordinary.

Would you say that Alpha NR V2 is roughly performance equivalent to the superseded Sigma NR?

So Alpha NR v2 would be the preferred choice over Sigma NR, and cheaper too?

Re: Shunyata Sigma NR v2 power cord
i have a sigma NR v2 in on demo, powering an everest (also on demo). while the system does some things *very* well, i fell the top end is rolled off, and i'm losing some detail / air on upper octave harmonics.
is this the effect of the NR in the wrong spot? i know Shunyata rec's the XC series for its power distributors, but the dealer only had NR on hand.
thanks for any input.Jays CD3Mk 2 transport + stillpoint ultra 6s

Re: Shunyata Sigma NR v2 power cord
So, I own a Niagara 7000 power conditioner. Which I like very much.
I was thinking of getting a Sigma V2 NR to power it. But now I wonder if the Sigma XC would be the better choice.
Any help for my decision would be appreciated.

Re: Shunyata Sigma NR v2 power cord
the cord from the wall to the distributor is the most important cable in your system. you cannot go wrong using the same mfg for the cable as the distributor (i tried diff brand cords into the everest; they didn't work as well as the sigma NR, which was still the wrong cord )

Re: Shunyata Sigma NR v2 power cord
Ultimately it's your choice. I've had different power distributors during the years. Furutech and Shunyata are the household names here.
I would probably get a Sigma XC regardless off the power distributor manufacturer. If you later come around to the Denali or Everest you have everything setup perfectly for your system transition. (Shunyata uses C19 IEC's though so other manufacturers might need an adapter unless you are custom ordering it with C15 IEC).

Re: Shunyata Sigma NR v2 power cord
Crion,
Yes I think I will center on getting the Shunyata Sigma XC. I may someday trial a Everest so it would be good to have.
Now to rob a bank...

Re: Shunyata Sigma NR v2 power cord
Try a Firebird HC.
The added silver in Firebird will be an improvement over Hurricane HC.
Sigma XC uses the new conductor with silver in it.
Probably compares better to Firebird
I'm not a fan of mixing and matching brands.
If you have a Niagara stick with AQ.
But, if you have plans to change to a Shunyata distributor in the future.
Then consider a Sigma XC.

Re: Shunyata Sigma NR v2 power cord
ozzy, if youre sticking w the niagra, find a way to demo the dragon. i've one in at present and it is awesome. (using it to power a custom-built distribution box). quiet, extended, and dynamic AF.

Re: Shunyata Sigma NR v2 power cord
My entire system uses Shunyata power cables so I’m a big fan of this company. I recommended the AQ Dragon since it is a stellar cable and the conditioner is an AQ. And, yes, the Dragon is pricey but it’s exceptional.
If replacing the AQ N 7000 was a consideration, Shunyata Everest with Sigma 2 XC or Omega would be my choice._______________

Re: Shunyata Sigma NR v2 power cord
strangely i'm demoing both the sigma XC and the dragon. after the swap, i'd offer the following:
dragon is more dynamic, better air. sigma slightly warmer with blacker backgrounds but at the expense of being slightly closed in up top.
if i was listening to shit digital, sigma would be preferred.
if everything upstream is up to snuff, dragon.
if cost was the same, i'd go dragon. if its $4k difference to you is a personal matter
(i'm listening to sigma XC with grateful dead @ 1970 live disc, its a wonderful cord from the wall, and with none of the reservations i had about the NR version, which was poorly suited for this application.)Jays CD3Mk 2 transport + stillpoint ultra 6s

no adapter. using a custom box, the closest equivalent is the $1200 furutech GTO-D2.

Re: Shunyata Sigma NR v2 power cord
Two days ago my Sigma NR V2 arrived. I have had time to do a quiet listening on both the DAC and the Amplifier and although in both positions it produces a clear improvement over the V1, I have finally decided to stay in the DAC. I'm not going to try to explain the improvements because Puma and SC Audiophile have already done much better than I can. I can only say that I will inevitably have to go (little by little) replacing my V1s with V2s. Just a request to Caelin, please a little slower the upgrades (I'll be ruined) we are all already turning years and at certain ages overwork is not good for health. Rest, take your work easy .........

Re: Shunyata Sigma NR v2 power cord
Regarding the next device to receive a V2 was the Preamplifier, I have the following problem. My Preamplifier is an Audio Research that has a C19 connector, if I change the Preamplifier, later on, almost certainly the new one will come with a C15 connector, then I would have to sell the C19 cable with its corresponding loss of money and I don't like the idea.
Regarding the Melco S-100 / Pink Faun, this morning I decided to do the test, after it had been working the 500 hours that they told me I needed the Ultra OCXO, to be at 100%.
First I connected my old EtherREGEN to the current for 1 hour to warm it up and while I have been doing a critical listening with the Melco of two works: The 1812 in the version of Reiner and CSO and the Prelude number 22 of the OP 28 of Chopin by Claudio Arrau. After switching to the ER, the 1812 sounds good, but …… in a non-comparable way, drier and more gritty, with “harder” highs and less orchestral density. The passage to Chopin has been even more illuminating; the two pianos are simply not comparable. with ER it's fine but, friend, with Melco / Pink Faun the piano has a presence, a body, a much better color.
I have always said that ER is a great buy for its value and the Melco / Pink Faun, having to pay the OCXO plus the installation labor, much less advantageous. Now if we talk about absolute musical value, they are simply not comparable.Francisco

Re: Shunyata Sigma NR v2 power cord
The nice thing about the ER though is that you can easily upgrade it with ext_clock, Sigma V2 CGC cable and Farad PSU. Arguably it will be in a different pricecategory then but you can do it in steps..

Re: Shunyata Sigma NR v2 power cord
I have grounded ER with an Entreq Olympus (Silver and top of the range) and I don't like the result. I have had ER connected with Farad, I sold it when his replacement Paul Hynes SR7 arrived and with this PH I have done the test today. Unless an external Clock totally changes the sound of the ER, they are two different devices.

Re: Shunyata Sigma NR v2 power cord
We are comparing apples to kiwis here. Shunyata Sigma V2 CGC is almost 3 times the surface area of the Entreq Olympus GND cable and also have that mix of core Ag outer Cu that we know works well and sustains the benefits of both and also the KPIP process which further elevates the SQ.
In my system going from the early CGS10 (10ga OFC without KPIP) to the Sigma v2 CGC was significant even though I didn’t plan on it.
Ext_clock OCXO with an Alpha v2 Clock 75ohm cable was also a large step.
So yes, I don’t think you’ve heard the full potential of the ER yet.

Re: Shunyata Sigma NR v2 power cord
I received the Shunyata XC demo today to use with my Audioquest Niagara 7000.
First impression, compared to my reference power cord it has slightly different (more pronounced) treble and mids the bass is a little subdued. Soundstage is about the same. Not the huge impressive difference I heard with the V2 Sigma interconnects.
I'm going to continue to play familiar tracks for the next several days before re-inserting my reference.

Re: Shunyata Sigma NR v2 power cord
In my experience, Shunyata power cords take about 4-5 hours of continuous play to really open up. Which is really very short time. Out of the box, they do sound.... let’s just say average. It’s astonishing just how much they improve in such a short period of time. Of course, this is just my opinion, my experience, at least with NR and XC and EF v1 and v2

Re: Shunyata Sigma NR v2 power cord
Puma Cat, thyname,
Thanks for the comments. I have 20 days for audition so I will play them for awhile. After 2 days of playing them about 5 hours each day they are better. Still not impressed with bass definition.

Re: Shunyata Sigma NR v2 power cord
I would agree. I'd estimate that they do the majority of their settling within the first 5-6 hours, continue to their almost fully settled state in 48 hours, especially if they've just been purchased and have arrived from shipping via the logistics company. They'll be fully settled within a week. From what I've been able to determine, the "settling response" is like a negative log curve function as shown,

I upgraded the power supply on my Gigafoil v4 to a Weiss PSU 102. It’s very nice step up. But with the new model, you’re looking at $2000 before even investing in a SOTA linear power supply.
