"The reason this review is easy, is because the DEEP=CORE works. Starting with the 5u4g rectifier tube, the faint hum was gone. It was replaced by an inky black background. Simple, easily, measurable, and effective. I assumed that replacing the 5u4g with the 5AR4 would likely reduce hum. Instead to my surprise I was greeted once again with an inky back background. No hum, no hiss, just silence. Of course listening to music sounded great, and I felt like bass was cleaner. To have no audible noise from an 8 watt single ended tube amp with 0 feedback using a 104dB efficient headphone is simply unreal and justifies the DEEP=COREs purchase for me."
"Based on the fact that I do not have a dedicated circuit for my audio equipment, and I have appliances that run on the same circuit, the DEEP=CORE is simply a no brainer and a must have for me."
Clement Perry with Stereotimes said:
"The DEEP=CORE 1800 lowers EMI/RFI gremlins quite effectively. Offers the biggest bang for the buck we've tested thus far! "
Here is the latest customer feedback:
Well, it may be the BEST decision I've ever made in my years as an audiophile!! The dynamics, noise floor, realism, and ease of effortless musical flow are unbelievable for an under 1K purchase!!! It's like a new system, and sounds like one costing much more. I am truly blown away at the upgrade! The control on back of the unit to fine tune the sound is amazing unto itself! These products truly deliver, and I am one happy listener right now!! Can not recommend enough! If you're on the fence, just do it!!
Call me amazed at Core Power, and I've never been led down a wrong road yet in all my dealings with Walter either!!!
Thanks so much...Brian.
To clear up any confusion on the differences between Deep=Core and Equi=core:
Equi=Core is a balanced line conditioner. It removes up to 20dB of common mode noise from the line. With lower noise you can hear more low level resolution and inner detail. It also has surge suppression.
The Deep Core 1800 is a multi-function power conditioner that re-defines the category. The Deep Core 1800 is designed to not only provide clean, spur free power but it also allows the user to optimize the power delivery interface via a user adjustment. The optimization of the power delivery interface can significantly affect sound quality as the power company is a major contributor to attributes such as poor noise floor and dynamic range of the system. The Deep Core 1800 can be used with almost any system configuration providing optimized power for both source components and power amplifiers. It will work as a stand alone device, in front of the Equi=Core 1800 or older 1200, 300 etc, or in front of any other power conditioner you may already own. However, it works best when used in front of a quality power conditioner, like the Equi=Core 1800 balanced power conditioner.
In the ToneAudio Dec 2019 review they say:
"Bottom line, it works"
"After trying the Deep Core in a few different system configurations, it unmistakably does reveal more music with no shortcomings. Transients aren’t compromised, and the bottom end is not smeared – another sin that more than one power conditioner has committed during the audition process. Best of all, more musical detail is revealed, without the mid to high range becoming etched, harsh, or overemphasized. This is much harder than it sounds. That’s why most power products ultimately end up being unplugged in favor of the existing devil in the wall socket."

In their December 2019 review Stereotimes summed with:
"Placing the DEEP=CORE 1800 as the front end for power in a variety of configurations, I noted that the signal was indeed enhanced – more palpable, more engaged, with a touch more life to dynamics and cleaner, with a touch of blacker background in quiet areas. These attributes were subtle but apparent."

User feedback on the Deep=Core:
Walter, I want to thank you for the advice on your Deep Core product line.
The Deep Core 1800 has the following major attributes;
- An Input circuit that features a unique DC snubber which stops any DC, constant or transient, imposed upon the power lines from passing through the Deep Core and into the system. DC can saturate the transformers or source components and cause voltage fluctuations.
- After the DC snubber the Deep Core has a complex common mode filter designed to suppress any RF signals that may be riding on the power lines. This RF energy can raise the noise floor and affect the total dynamic range of the system. The EMI filter is implemented with high quality magnetics that will not saturate under high current conditions.
- After the common mode filter a second EMI/RFI filter is implemented that further cleanses the power of unwanted out of band products. This additional filter includes integrated surge suppression to insure that no high voltage transients, such as the voltage from a lightning strike, will pass through the system.
- The last stage of the Deep Core contains the adjustable power delivery interface. This interface changes the relationship between neutral and ground and allows the user to optimize the power delivery to your system. This unique capability allows the power to be optimized for each individual system.
The Deep Core 1800 should be connected in front of your power conditioner as it is the “final” word in preparing your AC for a good power conditioner. Its unique ability to not only fully cleanse AC power sources of both DC, EMI and RFI noise, as well as to match your AC to your individual components, is unique among competing products. It can also be the foundation of a full A/C cleaning system solution.
