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.

From what I have read, the EQUI=CORE products would appear to be good, and I know Mark was working on a 240Vac version for me and others on this voltage. Mark was also supposed to be modifying a Deep Core to do the same. Obviously there is a bit of work to do to make the product work firstly in the local market.

Thanks to Dan for keeping the information flowing. I hope Mark will do the same.

I have my Prima Luna Dialogue Premium HP plugged in my EC 1800. I would say I've had the same experience as luvrockin above when compared to plugged directly into the wall. It is also much quieter than the Shunyata it replaced.

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

As I previously stated ALL of my gear goes through the 1800 including the Lyngdorf2170 integrated amp.
One massive improvement I did notice is how well the 1800 cleans up our poor local power which prior to this was subject to random clicks and pops.
I cannot swear to it that the Lyngdorf sounds better through the 1800 but it certainly does not sound worse and now I never have any unwanted odd electrical artifacts from the mains.

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
