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.

That I think is easy to measure with a simple device. Each piece of equipment will react differently to voltage fluctuations, and of course it will also depend on the degree of fluctuations. My turntable doesn't have much tolerance for it, nor does my integrated amp. The tape deck doesn't care much unless it is totally out of control.
Your amps power supply should be quite good. But it is not Lamm amps that Whart has, those power supplies probably cost more that your entire integrated. That's why he abandoned even best conditioners of the time.

Whart, thanks for replying. I didn't realize it was a fairly new development that power conditioners can fully power amps without current limiting  I think there are plenty of people around who've been plugging their amps into the wall, rather than the power conditioner to this day, judging from how frequently that topic comes up.

Both Shunyata, and especially Audioquest , address in their literature they don't limit current to amplifiers. Audioquest advertises their Niagara models have a substantial power reserve for transient peaks, if I'm saying that correctly. It's interesting to know it wasn't always that way.

Inna what kind of device do you use to measure that. I saw something being used on a Shunyata youtube video that played out loud the line distortion, and provided a measurement.

Mike, I don't exactly have to measure it, I use PS Audio regenerator and it shows me voltage in real time.
People often plug directly into the wall their power amps with robust power supplies. Your Luxman integrated is three components in one box - phono stage, preamp and stereo amp.
By the way, think of a power cord as an extension of power supply not as an extension of wall wiring, this is a more correct view.

It isn’t a new concept at all. For example, Tice was doing this with the Power Block/Titan combo decades ago.

Sometimes, the biggest problem with current limiting rests not with the power conditioner or isolation transformer, but with the electric utility itself.

I own the Audioquest Niagara 7000. It stabilized my voltage, cleaner up
my noise problems and provided endless power for my amps which are quite power hungry. It is probably the best single purchase I have made.
It  also is a fine power surge protection system. But the real beauty is in the change you will experience in the sound coming from your system.
I would call it pristine compared to a wall plug in my area.
