Core Power Technologies

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 the original Deep Core design was supposed to be a front end 1st in line solution plugged directly into the wall, where up to an EQ 1800 could plug into. Many of those who ordered it made their orders with this in mind. After Deep Core V2 blew up Droleg's system and blew out fuses in Ozzy and Lak's, it was found that DC would handle nowhere near an EQ 1800. Please let us know what it's power handling capabilities will be.

@chazzzy007;  Correction chazzzy007 the version II Deep Core blew fuses in ozzy and Lak's system and damaged drloeg's (was either Dac or preamp) and had to go back for repair. BTW the Deep Core at the time the damage occurred in all three was being used to power one or two components it was NOT overloaded and trying to power an entire system (although we tried that also) as others would have you believe. Funny how I was told that there was a team of Marks personal testers that had extensively tested the version I and II Deep Core and it was supposed to be safe to use on an entire system powering a 1200 or 1800!

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.

Dan have you tried plugging your amps directly to an EQ1800?
I have a 5 channel BAT VK-6200 and the results are superb.
The EQ-1800 handles it easily.
