My opening order has shipped. One 6000, two 2000's and a bunch of Sigma PC's. Very excited to try the full Denali suite with Sigma PC's in my system. SET amps and horns - a good test!

Very awesome Mike! Looking forward to the test.

Mike, I couldn't be happier with my Denali purchase. What began as a audition in my system quickly became a purchase with the 6000T never leaving.

Caelin and his Shunyata Team are top notch. They patiently answer any questions and never try to up-sell their products. In a couple of instances they have worked with my dealer to make sure my auditioning experience is meaningful.

The Shunyata Denali is easily for me the most important ancillary component that I have purchased this year. In fact it has made 100 lb.s Torus AVR 20 redundant. So that goes up on the block soon.

It is amazing to me what clean power does for your system. Not just the power coming out of the wall but what the Denali does to clean up the noise being fed back onto the mains from your other components. Especially digital.

Help me understand why? From the web site, the primary purpose of the Denali is to eliminate noise being generated between components. The signal being fed from one component to another comes after the internal power source (transformer). Since the signals passing from component to component do not go through the Denali, how does it eliminate harmful noises (assuming there are some) being transmitted through the interconnects (which some manufacturers also claim eliminate noises)?

Hi Hiker,

The noise from one component (e.g. digital ones) goes back out its power cord and enters another component (e.g. preamp) through its power cord. The Denali has greater than 60 dB of noise suppression between its Zone 1 and Zone 2 duplex outlets. So by plugging a DAC in the Zone 1 duplex and preamp in the Zone 2 duplex, this noise can be defeated.

Best,
Ken

Here we go again, I guess Denali is in my future... There will be a bunch of Tritons V1 & 2 in the market.

The Tritonv2 and Typhon are still the TOL, but from what I have been reading there might be situations where a Denali works better. Anyway, I am still very, very happy with the sound of my Shunyata gear at this point. My spare change is going to my Magico M3 account.

Apparent noise in electrical current traveling in-and-out of power cables and being exchanged among components is news to me. As is the news that the internal circuitry of quality components is not designed to handle such noise (assuming it exists) and produce a clean signal.

It really isn't much different than noise traveling through the AC lines from a computer or refrigerator compressor.

Heard a Denali powered system with Wilson Yvette, Ayre AX-5 Twenty, dCS Debussy and Transparent cabling over the weekend and I was impressed. Smooth as butter with absolutely zero brightness. Although I wish there were some bass heavy music. Also heard Sabrina with Ayre QX-5 Twenty (amp and pre are Rouge Audio) on Audioquest Niagra 1000 but much prefer Yvette system.

Unlike my audio components, my computer and refrigerator are not connected to a dedicated A/C line using a high-quality wall outlet and Wireworld power cables.

That dedicated AC line is still connected to your main or sub panel. Anything connected to those panels can impact whatever else is runs back to the box. That doesn't mean do nothing. Using dedicated lines and high quality connections as you are help.

It's hard to know where to begin with comments like these and I'm not sure where you are headed with this, so I'll contribute a few facts and step away. Its called alternating current for a reason. Components sit at the front of the electrical chain, not at the end of it. The further away you get from electronics the less well they can "see" noise, electrically speaking, but the radiated EMI and RFI within close proximity to electronics is easily measurable and when it is eliminated or reduced, its easy to hear and see if its a video or med. imaging system.

We have performed these demonstrations live at CES and other shows. We also have a plethora of video's on our You Tube channel that explain in great detail the science behind what we do. Yes, its well understood by any electrical engineer that electronic's with bridge rectifiers and or digital circuitry push back noise energy onto the electrical line. This can create high-frequency noise energy (harmonics) that are 50 times the line frequency.

There is no such thing as a power supply in audio, studio or medical imaging systems that can manage to eliminate that much high frequency noise on their own. We build a series of power cords with small filter-sets built into the IEC to help minimize the noise being kicked back from the power supplies of electronics. If you use a Fluke 43 power analyzer, the noise reducing effect is easily measurable and still, a product like the Denali will improve the perceived noise level in a dramatic way above and beyond any power cord. The power cord is the first step in minimizing noise radiation. We also make shielded power cords and there are hundreds of these that are now deployed in medical systems. Again, to minimize the effects of EMI.

Look, we have nothing to prove here. Our products are used at SkyWalker, Pink Floyd's Astoria Studio and David Gilmour's home studio, Rick Rubin's studios, James Guthrie's Das Boot studio, Sony Japan and countless others that have compared products and who's sole passion is achieving the best performance possible in audio reproduction.

Our products have found their way into Electrophysiology Labs across the country and have literally eliminated noise from these systems to the point that they can no longer measure noise. I know because I went to each of these EP labs and set up our system of shielded power cords and Denali technology-distributors. When the EP Labs were using isolation-transformers to "block" external grid noise (they also block noise coming from electronics and keep it in the system --a two-way brick wall), they had endemic, intractable noise issues that they measured at .5 (their measurement). Switching in Denali technology products (which filter noise from the grid and _from electronics_) lowered noise to .01, which is the limit of their measurement systems ability to measure noise. In addition, the EP Physicians could see the topography of the heart far better, which has lead to better outcomes for patients and easier, quicker procedures. This too is well documented from multiple Physicians and OR's and is on our web.

I have also been asked to consult on the build out of new EP labs in Minneapolis, Louisville, and Pennsylvania and a new Neuroscience center in Minneapolis, not because we make cool boxes, but because we know electrical systems and how to set them up better than anybody in the business. I can talk with these engineers, electricians and Physicians because I have worked with a genius in this field for 17 years. I'm no EE, I'm just a guy but I know a thing or two. I do all the travel to the studios, hospitals, reviewers and trade shows and I see and hear the results of quality electrical set up, Denali and power cords firsthand.

I don't think you know enough about us to stand back and judge anything we manufacture unless you look into things a bit further. Caelin is a former NSA scientist and developed low level signal acquisition systems for the military. He is also a Master electrician, as are his two sisters, his father and his brother.

Power cords are an extension of the primary winding in the power supplies of electronics--not the last six feet of miles of wire. A well designed power cord keeps the high frequency noise generated by electronics from radiating back into the power supply and minimizes the noise radiation from affecting other electronics. They are not intended to be a panacea, just an added protection from near-field EMI and RFI.

I refuse to get into an argument and I certainly don't need to vet the work we've done. Do some home work, watch some of the many video's that explain our technologies and science. Then call me and ask your questions, I'd be happy to answer. Playing this out on forums strikes me as something more than just seeking information. Not saying its disingenuous, but it is also not a well informed opinion.

If you do have intellectual curiosity, I'd be happy to answer your questions personally. I don't have the time to spend arguing points that have already been well explained on our web and many other places. Power cords, whether shielded or filtered are very well understood compared to 20 years ago and we have played a role in explaining and measuring exactly why they could play an important role in audio and medical systems.

You could start with these two video's.

The first in a simple noise test involving Denali: https://www.youtube.com/watch?v=Z6f1kwyZbM8

the second is an ASCC test that demonstrates why a "better than stock" power cord has a dramatic advantage in delivering peak-current (the most important aspect of performance for all analog output electronics because this element affects timing and dynamics in sound)

I don't disagree. But this assumes that there is noise in the line and that if there is noise in the line it is not being handled by the power cables (a claim put forth by Wireworld) and the components. The main premise of the Shunyata Denali is not the elimination of noise coming from the grid but rather the elimination of noise, i.e., "high-frequency", being generated by the inter-connected components themselves. It seems to me that this is an issue worth discussing with the manufacturers of your components. I own a McIntosh MC452 amp and an Accuphase P-6100 amp and both manufacturers recommend connecting them directly into the wall socket.

[Mike]

Grant - thank you very much for responding.

Hiker - get yourself an Entech Line Noise Analyzer (same one in the video). They can be bought on eBay for under $100. You will be shocked to hear the noise on your line. By all accounts, the Denali is a tremendous group of products and lowers the noise by a significant amount. The improvements to sound with clean power is bigger, in my opinion, than a cable or even a component change in many cases. Just because you don't think it's there; doesn't mean it isn't.

Measure to verify.

I just did some evaluation of the Denali 2000T in my system. In my system it was an improvement.

I tried 4 different pairs of power cables between my amps and the Denali. The differences between them were MUCH more apparent with the Denali.

I believe in power conditioning and power cords as a smart investment. I started with low end shunyata then standardized on all things audience including their upgrades. Then moved Cardas Clear Beyond and JENA Labs new sequoia. Now have inserted Isotek Super Titan. Each time the graduation pays off. Less grain, more spaciousness, better microdynamics, more tangible foundation, etc. I think all these companies make great gear especially as you climb the summit (one area of audio where I have not yet experienced law of diminishing returns). I have heard the Denali is a game changer. Based on medical/hospital application of clean power/noise reduction, it sounds like a new level performance is tied to Denali. Appears it may be more than a halo product - eager to hear more about the new technology and standards that went into it.

has anyone compared the results of putting a furutech flux 50 inline on amp direct to 20 amp circuit vs feeding amp thru a denali. i currently use shunyata mpc12A for components with alpha hc to dedicated 20 amp and amp running direct to 20 amp. thx.

I have three dedicated lines with top end Furutech outlets on each one, and a Shunyata Cyclops v1. on my ARC REF 75 amp. Just for fun, I picked up an Entech niose detector, feeling fairly sure (perhaps a bit smugly) that I would find minimal issues. Was I ever surprised! Not only was there AC iine noise, I was also picking up a radio station on my dedicated lines. The Cyclops reduced the AC noise by 70% according to the Entech. The question is not do I have noise in my electrical circuit, but how much of a problem is it? I think I may see a Denali in my future...
