Core Power Technologies


Does anyone know, is Core Power Technologies still around? I was considering purchasing (2) Ec1200’s but don’t want to be in a holding pattern for the next year. Are they or (Mark) still in existence? What’s the lowdown or suggestion of comparable item.

Core Power Technologies is still very much around.  Things are in a transitional period right now. I will be able to share more later.

Thanks,

Dan Wright
I have not used, seen or heard the product.  It is my understanding however, that it has been re-engineered to handle higher current. I do not know about the production or availability status of the new design.

I will share what I know.

There was a Deep Core design and I have spoken with the engineer. There was an issue with a small number of these first units.  It was based on the units being used to deliver more power than they were designed for.

I know that this has been redesigned and tested positively.  I do not know what the production status of these units are, beyond this point.

To my understanding, Deep Core withstanding, there have not been any reliability issues with the Core Power '1800' and '1200' units, correct? I have used the 1800 myself at shows with great success and I was very impressed with the product.

Thank you,

Dan Wright
I have more information about the Deep Core.  There were two initial version released in Beta form and problems were found in both. A third version has been built, tested and proven to work and test well by the contract mfr. that did the initial builds.  Apparently a couple of errors were found and corrected from the initial design. I do not know what there is in inventory as far as production goes, nor do I know the time frame going forward. I personally would not ship this product without thorough vetting of my own.

Thank you for the feedback RE the Balanced Power units, 300, 1200, 1800, etc. It confirms my confidence in this line of products as quite solid and the reviews certainly support this.

Thank you again for the words of support as well as positive feedback about the 1800 products.

Dan Wright
Hi guys, thank you again. I am quite pleased with my experiences as well as the feedback and reviews that have been and are still forthcoming for the Equi=Core products: 300, 1200, 1800.

I know nothing about the power cords. I am not a cable mfr.

I am going to do my best to obtain a V3 Deep Core and do my own testing no matter what.

The Equi=Core products will be in production again. Some things have to be worked out, but the product is excellent and is still very much alive!

Thanks,

Dan Wright
Further discussions with engineering regarding Deep Core have assured me of what the problems were and that they have been addressed. While I don't have full design knowledge of the product, I can easily understand the reason for the failure modes, and am confident that the issues have been resolved. I also now understand the DC blocking and AC filtering design purposes. As for the tune-able feature of the design, I would have to evaluate, listen and measure a unit here to say more. I have great respect for the engineer and engineering involved.

I still hope to get a unit in-hand to personally evaluate. I do not know what production status or date of availability is at this point. I have no control over that at this time.

I will continue to do my very best to keep everyone informed regarding production and availability of products as things progress and I am better able to give concrete answers.

As many of you know, who have worked with myself and my team at ModWright Instruments, customer service and satisfaction are paramount to myself and ModWright's business model.

Thank you,

I have made arrangements to have a current working Deep Core unit sent here for evaluation. The production units will have one minor change that is not present in this unit, but the key issues that matter are all current in this unit. I will be receiving engineering measurements as well as a working unit to evaluate.

Thanks,

Dan Wright
It is my understanding that the current design has been proven to handle 1200W continuous power load. A final change made to a component in the design to better reject heat should allow for up to 1800W continuous power.

Now, audio power is not always constant and there are transient peaks. At the same time, even with a Class A amp, it is VERY unlikely to even draw a constant 1200W of power.

The beta units did have a design flaw that was not caught initially. These issues have been resolved and engineering indicates that rugged testing has proven this to no longer be an issue. 

I am expecting a unit to test and evaluate.

I realize that the product was sold as an input solution for the 1800. It is possible however, that there was miscommunication between marketing and engineering. However, the new design is capable of handling much more power and this may now be a possible combination.

I personally would dedicate the Core Power unit to handle all line level and source components, but NOT the amp. I typically connect my high current amps directly to the wall.

Thanks,

Hi, I believe that we DID do this actually at the show.  At shows, where power is SO BAD, I will do this as long as I know the power conditioner or isolation unit that I am using will be lossless.  In the case of the 1800, I agree that there should be no problem in doing so. We had GREAT sound at that show, with Deadalus speakers, Skogrand Cables and ModWright Electronics!  Truly great sound at that show!

With regards to the Deep Core, I am just hesitant until I test it further, insuring that the Deep Core itself will not current limit and can handle  this.

If the Deep Core can be used in this application, then it should be ideal.  I just can't confirm this until I test a current version of the Deep Core.

Thanks,

Dan
Measurements from engineering with the current Deep Core design show AC noise measurements as folows:

3Vpk-pk incoming noise on AC main.

15mV pk-pk outgoing noise on AC main after Deep Core.

95% reduction in AC mains noise? I would say that is good!

This measurement is JUST AC noise. It has nothing to do with the adjustment feature of the unit.  It also blocks all DC on the AC mains, which is a great feature. This is what can cause transformer hum in systems where other current-heavy loads, such as resistive heating elements, inject DC into the AC mains feeding your audio gear. Tube gear is particularly sensitive to this, as are many SS amp power transformers.

Thanks,

Dan

That I don't have I am afraid. I only have test measurements from engineering for the Deep Core only.

Dan
Once the Deep Core design is solid, I see no reason at all why products could not be produced for 120V and 240V.

Dan
Thank you for that. If I did not believe in Core Power Technologies, I would not be involved at all.  They are great products, and it is time to take things to the next level.

Dan Wright
I am honestly not at liberty to say exactly what the initial design intent was, but I do believe that it was not initially designed to handle 15A (1800W) of power.  It is my understanding that now, the unit has been tested at a steady 1200W load and with a minor change or two, should be able to handle the full 1800W.

As to the design itself, I would have to test it myself and see how it works. My understanding of the design as it stands is that it should work very well as designed. I will have the unit soon to evaluate and I can then make more intelligent contributions here.

It is true that I am always looking to improve products.  I first always want to be sure that a new design works as it was intended as basis of design.  Once that is established, then certainly, if I learn of ways to improve a product down the road, I certainly will.

Thanks,

Dan

I have decided that I will not be purchasing and taking ownership of Core Power Technologies. 

It is a great product and I expect that someone will take this opportunity and do great things with Core Power.

The direction that I am taking with ModWright Instruments and my own business model is such that I do not feel it is a good fit.

I have expressed this to Mark Schifter and withdrew my consideration to purchase Core Power Technologies.

Sincerely,

Dan Wright


In lieu of this decision, while I have not yet received a unit from engineering, I contacted the sender and asked that it either not be sent or we will refuse shipment.  Given this decision, it would not be appropriate for me to inspect a unit. I respect the Intellectual property.

Thank you,

Dan Wright
