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.

Mike, you are about to spend $4000 on you don’t know what. It is unknown how it will work in your set up, by itself and in comparison with other devices. And it doesn’t stabilize voltage.
I just felt that I had to warn you.

By the way, I never read any review of anything that would tell the whole story.
Another point, since it's important to you, absolutely any company can disappear at any moment, don't count on any service long term.

PS audio Power Plant 15 Hands Down. Helps remove THD Total Harmonic Distortion. I owned a Niagara 5000 for about 90 days thought it was over hyped. You cannot trust most reviewers they don’t get paid to write negative reviews.

For example a reviewer that states  that an Audioquest HDMI cable that cost $2,500 is much better than an Audioquest HDMI cable that cost $400 both 3.5 M

additionally people that drink the cool aid and say that that can hear a difference between two very high end Audioquest speaker cables a $5,000 cable and a $7,000 cable

Mike, I have recently done an extended test of 3 power conditioners side-by-side. They consisted of the Niagara 5000, Denali 6000 and the Ansuz power conditioners. As you mentioned, I did experience a hum in the Niagara 5000, which I found disturbing. While it did improve dynamics and bass extension, to  me it seemed to veil the music a bit. The Denali was more transparent and did not seem to cloud the presentation as much as the Niagara. Ultimately, I chose the Ansuz line as it presented the cleanest, most transparent sound. It is worth mentioning that I use a Hegel SS amp and my speakers are fairly efficient at 93db. I started with the entry level Ansuz X series conditioner and an Alum power cord from my outlet and an X cable from the conditioner to my amp. The Ansuz line seems to perform best when you use their cables. I started with the entry level as I wanted to limit my investment and live with it long term to ensure that I was on the right path. I have been using it now for a few months and very pleased. I can see myself upgrading to their higher end models in the future. I hope this was helpful.

I started a "Do I need a Conditioner" thread a while back and looked into all the suggestions.  Decided on Equitech balanced power transformer. Had used older Shunyata and PS Power Plant. Equitech is much better. Shunyata cleaned it up but sucked some of the life out of it. PS could only run the front end and didn't make much of a difference that I could tell. I think maybe Niagra 7000 is also balanced power, not sure. Of the two I would take the AudioQuest. But do yourself a favor and check out Equitech. It is money well spent. Makes the rest of your system sound like it cost twice as much.
