In the Sept 2020 Equi=Core 1800MK2 review in Positive Feedback said:
"So how does the performance of the Equi=Core stack up?
To be frank, it is a giant killer." "Making the switch to the Equi=Core removed that noise, and this alone left me quiet satisfied. As I listened to the system with the Equi=Core I also noticed a slightly more relaxed top end and more bass definition from my amplifier. I have found that tube amplifiers in particular really loved the Equi=Core 1800 MK2."

"When I compared the Equi=Core to my PS Audio Power Plant P12 I found that the systems sounded incredibly similar, however, the PS Audio Power Plant P12 actually caused more transformer hum in my tube amplifiers. When you consider that the retail price of the P12 is double the cost of the Equi=Core, and that the P12 is only a 10 amp unit, it paints the Equi=Core’s value proposition in an incredibly good light, and makes it easy to recommend."

The new Equi=Core 1800 MK3 is a full 15 amp, 1800 watt, balanced line
conditioner. It replaces the 1800 MK2 that received many exceptional reviews. It includes our new Wide Band transformer that works to a much lower frequency to remove more noise than the original units.

It supports 12 products thru its standard six $60.00 custom gold plated copper  Duplex A/C receptacles. It also offers surge protection in addition to sonics that typically sell for $3000-$5000.00 from the competition. This new MK3 unit also includes electrostatic shielding to eliminate AC noise without the downsides of normal filtering.

All units use series wiring and upgraded internal wire over the original 1800. The new MK3 is 17" wide to accommodate its standard 6 copper duplexes.

 In the 2017 Tone Audio review on the MK2 they said:

"I could wax poetic about this track and that, but a power product either does what it is supposed to or it doesn’t. The Equi=Core 1200 and 1800 conditioners deliver the goods and offer outstanding value for the price asked. They are all made by hand in the Core Power factory in Colorado. And for those seeking additional value, they’ve got an awfully good “premium” power cord that can be bundled for only $99. The Shunyata Venom used to be my budget go to power cord, but this one easily takes it’s place. Even if you think you have “clean power,” you’ll be surprised at what one of these do for the overall sound quality of your system. It’s about a 10-minute demo. Plug it in, listen to your three favorite tracks, then take it out and repeat. This is an easy one, folks. So what are you waiting for? Give them a call (770-667-5633), they love to chat with their customers."

What is Balanced Power?

In much the same way that balanced audio lines can eliminate hum, electromagnetic interference (EMI), and noise, the use of balanced AC power lines in sensitive audio, video, or computer installations can make an enormous difference in system noise and signal integrity. But power distribution in North America, unfortunately, is not balanced. The distribution standards currently in use were derived from practices established over a century ago, when electric power use was limited to lighting and motors —long before any AC noise sensitive applications existed. The emphasis then was on convenience (from the power utilities — standpoint) and safety, but not noise cancellation

Balanced power is not a new design or approach in power conditioning, however up till now its been very expensive because only small group of manufacturer’s specialize in selling Balanced Power. It’s a rather simple concept; in your home, the AC wall socket that you normally use has three conductors: hot, neutral, and ground. Normally, if you measure the hot to ground you should get 120 volts, and if you measure the neutral to ground you should get 0 volts, but more often than you would imagine this is not what happens, i.e., hot vs. ground might be far less than 120 volts, and neutral vs. ground might be far more than 2 or 3 volts. These offsets produce common mode AC line noise that becomes audible in your audio system.

In a balanced AC circuit, hot vs. ground, and neutral vs. ground will both read 60 volts. In other words, the hot and neutral conductors are both at 60 volts. Since these voltages are of opposite polarity though, and given that most interference in a typical AC line is common between the two lines, the noise in the lines is eliminated when the two lines are added together. This is effectively known as Common Mode Rejection (CMR).
