Has anyone tried puritan 1512 or anything else from them and compared against Niagara/power plant? The power plant line is obviously a common love here, but just checking some other options while im at it. Niagra appeals to me because it also has pretty high current capacity and I wasnt sure if anyone had actualy compared them.

I’d like to hear about that comparison as well. That and also the Deep Core + Equi Core combo from Underwood HiFi.

According to Puritan, the PSM1512 is just two PSM156’s in one enclosure. I know that @Christof uses the PSM156 and has experience with the PowerPlant 3, so maybe he could share his thoughts on the two.

Yeah I have the 156 and the powerplant 3. They sound similar to me, they both brought some extra air and smoothness to the treble but I didn’t do much of a comparison, that was just my quick impression after plugging them in.
The power conditioner / regenerator for me is more about the features and ease of use then the sonic performance I get from it. I like that the 156 doesn’t have much of a power limit on it, you’re basically capped at whatever wattage the outlet can provide, while the pp3 does I think 300W continuous at most with short spikes above that I believe. I was hitting the capacity of the pp3 so I had to be careful about what I powered on.
I’m not a fan of how the pp3 works. In my system, it runs hot, and takes up a lot of space. The 156, is small and runs cool. I can stick the 156 under my rack and not worry about it getting too hot. I like the idea of regeneration instead of conditioning but I didn’t really notice anything different about the sound when I was listening. But like I said, I didn’t put much effort into comparing the too.
I’m hoping to sell my pp3 if you’re interested. I will be keeping the 156 though and might try their ground master accessory too.

Directly out of wall:
- average just under 1000 mV p-p
- max 1150 mV p-p
Out of Furman 15PF high output socket:
- average 50mV p-p
- max 60 mV p-p

Any stations coming through?

unfortunately not. Damn power is too clean

I feel like we should all test our power like you did. From the wall, and from conditioners.

@Draaly would you be willing to send your meter on a tour? I think this would be a fun experiment.

im sending this out to a few friends, but im more than happy to just send it on a tour so more people dont need to buy one.

I’m really curious to see how a Powerplant will perform.

Maybe create a thread for a tour (if you’re willing)?

I’d love to take part in the tour.
I have a PowerPlant 3, Core Power Deep Core 1800/Equi Core 1000 and Zero Surge 8R15W-I (which focuses on surge protection, but I think it has light conditioning).
It’s hard to do subjective comparisons between power conditioners because it takes so long to unplug and plug in everything, but the Core Power seems to be at least a good as the PowerPlant. It would be good to back that up (or not) with measurements.

Do you happen to know what the Deep Core and Equi Core do individually and then how they work together? And how they compare to a more traditional style conditioner like a Puritan PSM156? Not a lot of talk about them in the wild.

I summarized the details from this and this.
The Equi Core uses a balanced isolation transformer to split the incoming AC into two out of phase legs (-60 volts and +60 volts), establishes a new ground at exactly 0 volts and recreates the 120 volt signal. The process of recombining the legs apparently reduces noise.
For balanced power conditioning to be effective, the equipment you plug into the conditioner should employ a transformer based power supply, so something that uses a switching power supply may not benefit. Balanced power conditioners are also susceptible to DC current on the AC power line.
To combat the above problem, the Deep Core is basically a DC filter that sits in front of the Equi Core.

Sounds interesting, thanks for the summary!

I had to copy you and ordered the same meter 
Out of my wall direct I get around 150mV
With the iFi Power Station plugged in I get <40mV
According to the guide for the meter, anything <50mV is considered “low noise”
So far no radio stations
I need to do more testing at different times of the day
