Power Conditioners: Audioquest Niagara 5000 or Shunyata Denali 6000S


I’ve been trying to decide which of these two power conditioners might make a better purchase. Do any of you own either, have chosen one over the other, or better yet, gotten to A/B them? I’ve found some, but not a lot, of information online comparing the two. So I thought I’d ask if any of you might know something more.

They both come in at $4000 retail which is my budgetary limit. The Niagara is active, the Denali passive. Some threads compare the Denal a little less favorably to the twice as expensive Audioquest Niagara 7000, for what that’s worth. I heard that the Audioquest Niagara 5000 may hum or buzz under some cirumstances. Anybody have that issue? I’ll probably never get a chance to demo them out here in the hinterlands so I’m hanging on your every word before I drop another wad of cash on one or the other.

There is also an Audio Magic conditioner at the same $4000 price point, but I didn’t quite understand it’s function in comparison to the other two. I’ll have to reread that product description.Someone else recommended a Richard Gray model that confusingly turned out to be a giant-sized surge protector.

Anyway I’d appreciate if any of you have any input on this somewhat obscure topic of power conditioners. I’m looking at one of these two power conditioners as opposed to a regenerator, or pure isolation transformer, or other type of line conditioner. If it’s of any import my equipment is a VPI Classic 2 SE turntable with an Ortofon 2M Black moving magnet cartridge, a Marantz SA8005 CD player, a Luxman 507uX Mark II integrated amp, and Magico A3 speakers all to be on a dedicated line and plugged into the conditioner. I am not interested in purchasing used.

Thanks for any input or advice. I hope someone out there knows something about these two.

Cleeds I’ll take a look at the NEC. I’ve got an older copy. If not, I’ll use a 20 amp, 12awg hospital grade power cord having the C19 plug. I was thinking of being lazy and doing that anyway.

P.S. I looked it up online. At first glance It appears you have to put the Romex in conduit if it’s exposed. Since that would still be odd with the plug exposed. I’ll go with the 12AWG stranded hospital grade power cord instead. That should be about the same difference.

Now I’ll have to go back and put some conduit over an exposed length of Romex connected to my furnace, which did pass inspection years ago. That’s where I took the idea from. I certainly don’t want any code violations that would give my insurance company an excuse to not pay off a claim if the worst was to happen. Thanks cleeds fot the good advice.

Hi Skyscraper,

In a week I should be able to provide a more informed comparison that may be of some interest to you on the Shunyata v. Audioquest issue, but right now I have in house both an Audioquest Denali 5000 and the latest Shunyata Triton v3, which I am comparing to my current Purepower 3000+.  

As of this time, I have not had enough time to give thoughts on the Shunyata, but I was not impressed by the Audioquest.  Like pretty much every serial filtering conditioner I have tried, it presents a mixed bag of audio qualities.  In my system, it constrained the soundstage, bringing everything forward towards the plane of the speakers, and produced a more pronounced lower midrange.  If one's system is laid back, it may provide the sense of more excitement or jump factor, but I found it fatiguing. 

Caveat 1 - I only use power conditioners on front end components, not amps
Caveat 2 - my default power setup is pretty good, with all dedicated AC lines wired with Cardas in wall cable and Oyaide R-0 outlets, with an Eritech 10ft chemical grounding rod surrounded in bentonite clay.






Rzado, to be sure I’m not misreading you, you’re meaning the Audioquest Niagara 5000 aren’t you. I think you got a typo in there. I’m interested in how the two compare when you finished demoing both in your system. That’s good information on the Audioquest you’ve provided. Keep us posted. You’ve done a more thorough job wiring than anybody else I’ve run across. Must have been a fair amount of work.  I’ll be watching for your next post. Thanks,

Mike
@skyscraper, here are some thoughts on running romex or other rather simple cable directly from your breaker box to your conditioner vs running a high end purpse designed audio power cable from a wall socket to your conditioner.  From a current perspective, direct connection would be great.  From the perspective of any EMF around that cable that might interfere with other cables in the vicinity, perhaps not the best solution.  

Same goes (especially) for using budget power cables from a conditioner to your gear.  Why I hear you saying.  You just spent $4,000 to tidy up your power, so now its all good, right?  Yes and no, and the reason is that a power conditioner cleans up the power from the street, but can’t protect your low voltage/current signals in cables like IC’s and speaker cables from exposure to field effects from nearby high current power cables, even if the power running through those power cables is very “clean”.

As @inna says, good conditioning and good power (and other) cables work together, removing noise and reducing signal and field interactions, especially in crowded spaces near the back of each piece of gear or where low and high current wires come close to each other, cross, or heaven forbid, run in parallel.  Sorry to say its all potentially important.  

Best way to determine if it’s important enough for you to make additional investments is to try different power and other cables in your system once you select a conditioner.  Try the cable company lending library for a low cost way to trh before you buy.

I find that the better my gear gets, the bigger the benefits I hear from good power and other cabling. But frankly, good cables can make some even modest gear sound surprisingly better and good.

The better all your other cables are, the more likely your romex idea is to generate more potential benefits than penalties.
