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.

lp2cd, thanks for the explanation I have read up on the Furman IT Reference 20i. and will have to revisit the Equitech. I started researching the Equitech the another night but never finished. How much noise or humming does the transformer produce in either of your power conditioners? Noise is the problem I’ve been running up against with the isolation transformer type power conditioners. If I could find a quiet one I’d be much more inclined to go that route.

I too was put off by not infrequent reports of transformer hum in several models, including Equitech and Torus, who are another industry staple.  I was able to try out (with full return privileges) a Furman IT Ref 15, and it was completely quiet, but didn't do anything noticeable for my sound.  The problem is that until you install product X in *your* room with *your" mains electrical supply, you can't 100% forecast what it will do, or not do.

Audiogon just trashed my lengthy reply, and I'm not redoing it. Sorry. In short, both units are completely silent both in operation and the effect on the system. VERY worth it.

Since everyone is making recommendations I will too.
To begin with, I would get $130 Furman surge protector/ kind of conditioner and listen for a few months while trying to figure out what is not quite right if anything. Then tell us what happened and we would try to advise. There is absolutely no need to begin with fancy and very expensive units, whatever they are.
Mike, I might just have saved you thousands of dollars. On the other hand, saving too much on speaker cables would be a wrong thing to do. Cables for your set up should be both high resolution and slightly on the warm side of neutral, to be schematic. That's not easy to accomplish and should cost. Power cord for the amp is another matter but again - not $200 piece of junk.

Twoleft ears, yes the proof is in the pudding. Whatever I get it may or may not work or buzz, or do my laundry for me. I’ll hane to find out the old fashioned way and return the item if need be. I know they’ll stick me with the return shipping so I’ll have to make a good a choice as I can right out of the gate.

Lp2cd, sorry your post disappeared. I would have liked to have read it. I’ve had a few of mine go up in smoke too. A number of times Audiogon said my posts had not taken, but there they were when I checked. You never know. But you say both the Audioquest and Shunyata are are silent, so that’s encouraging. I’ve had two reports of the Audioquest Niagara 5000 buzzing, but none of the Shunyata making any noise, which is swaying me in that direction, I’ve a couple more models to research more now though. Thanks anyway for the short version.

Inna, nothing to do with this post, but I am going to get the Audioquest Rockets 88’s speaker cables that Magico recommended. I tied my brain in a knot trying to figure cabling out, and finally figured second guessing Magico on a subject I did not fully comprehend after hours and hours of studying, was a mistake.

I am going to approximate wiring by connecting my 20amp dedicated circuit’s 12awg Romex with a hospital grade 20amp C19 plug (I think that’s the correct number) to plug directly into the power conditioner. The power cord that came with amp will have to do until I get some other non-audio projects completed. Hopefully the power conditioner will clean up the signal so much, fancy power cords from it to the amp, cd player or turntable will be unnecessary. Only the interconnect from the CD player to the amp remains unaccounted for at present.

I am going to get a $4000 or thereabouts power conditioner, so I feel I’ve given my system a good shot at functioning up to it’s capacity. Also I want to feel that I have not cheaped out, which inevitably costs you more in the end. Once I get all my other non-audio projects completed, I may revisit my stereo system for tweaks and a turntable balanced supply device. Thanks again for your help, consideration and ideas.I actually have followed some, and you are responsible for my getting the Luxman amp. If you ever come over you can autograph it for me.
