I am curious if Doug Goldberg was part of the team or involved in the design of the Deep Core. It seems amazing that something simple like the Deep Core would have been designed so poorly given his background. Below is Marks post in October 2016 and a link to who Doug is.

Lastly tonight… I am pleased to share with you that my long-time and very dear friend Doug Goldberg has stepped up with two new designs that are going to change EVERYTHING we know about the Power Product Segment of our industry – just as some of his designs changed everything in the digital world back when we owned Audio Alchemy.
Doug is The Real Deal – he has worked on our nation’s BEST Fighter Jets where power is a very big deal. Doug’s first new product is Deep Core – and we expect that Deep Core will be available in 4 to 5 weeks. The design is in house and it blows me away. This is a very important product for our company and to be candid, Deep Core will work with every other Power Product and cable I’m aware of at this moment.
In Doug’s words –
The Deep Core is a multi-function power conditioner that re-defines the category. The Deep Core 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 prime power source is a major contributor to attributes such as the noise floor and dynamic range of the system. The Deep Core can be used with almost any system configuration providing optimized power for both source components and power amplifiers. Deep Core has the following major attributes;
· Input circuit 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 of 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 ensure 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 allows the user to optimize the power delivery to his or her system. This unique capability allows the Deep Core’s performance to be optimized for each individual user case.
Please note that we surely do want to tell you more about this “Adjustable Power Delivery Interface” and later we surely will. For now, we are only saying that this adjustment makes differences that will startle. Like our Balanced Power EQUI=CORE models, this topology is rooted directly in science. No hocus-pocus. A full and complete suite of measurements will be published in November for Deep Core and of course… the perfect companion product is our AC Balanced Power Source --- EQUI=CORE. They make beautiful music together. As this product is IEC in – and Hubbell Duplex Out – your existing power cords are welcome and will perform like you have never heard them. It’s going to be fun.
All 15 of those of you that paid and waited for EQUI=CORE 1200 or 1800 you will be given very special factory coupon to use if you find yourself interested in Deep Core. Continuing to say how sorry I am.
Thanks again – and my apologies for this ultra-long message
