Has anyone tried these stunning new CPT power cord?

   Considering the many, many brands of power cords I've tried in my very well accomplished high-end system, I have never been so impacted by these Core Power Technology power cords. Within a very short period(15-20) minutes my system literally came alive. Soundstage opened wider and deeper. The background became dead silent, space between instruments and stage members were more focused and everything sounded cleaner and musical than ever. My highs had a glorious crispness and symbols shimmered. Midrange through my 2" horn became more dynamic and punchy. My 15" bass driver tightened and dug low with great control. My Rel G1 which is a fabulous sub on its own but with a CPT 150 on it is another story. Running high pass from my sub to my Audiozen Noah amplifier, music depth is just stunning. Lower end bass is authoritative and clean with solid grip and impact. 
   My experience with these power cords is truly magical. The scary part of the above is I only have one 150 on my sub and one 300 from my wall to my 6 outlet bar. I still need 3 more to complete my system. I could just imagine the level after that...In closing, I cannot emphasize enough to try one of these in your system. I CANNOT and WIIL NOT take these out as they are that good. But hold your jaw, cuz what you've been listening to will just become real after Core Power Technologies. 

Cheers....and let the tapping begin.......

Robert,
500 hours will easily break in the HF CT-1E power cord. I doubt if you would even need 500 hours, more like 350 hours, but for your testing purposes 500 hours would be a very fair comparison. My only suggestion would be to make sure once the power cord is in place, don’t move it or jostle it.
What compoient is the power cord going to power?

Hopefully you are aware that comparing HFC products to other products is very difficult and frustrating because of the lingering effects of magnetic conduction, and the slow restart up of magnetic conduction.
This forces the listener to rely upon their memory of the HFC verses a direct comparison A vs B vs C etc.

In other words after the HF CT-1E power cord is burned in, evaluate it.
Take the HF CT-1E out of the system for a week so that the magnetic conduction effect is gone (using a non HFC power cord during the interim period is fine as long as your not doing any evaluations) and then compare the other power cords.
In my opinion if you don’t do this your test results will not be accurate.

Thank you both for your suggestions and we will definitely use 500 hours as a minimum for the burn in time, just to be fair to both manufactures. We have also found that moving cables can have a negative effect and even unplugging a cable causes a difference in the soundstage. Our thoughts are to test the HF cable first and than plug in the CPT and wait 30 minutes before listening to the CPT cable. Ideally we like to let a cable settle for 24 hours but this would not be practical for this comparison.

In my system the CPT has a dramatic effect on my Lumin, so I will swap out cables on my Lumin.

Robert, unfortunately the way you describe your listening audition is not going to be accurate and the listeners are going to hear the lingering effects of the HF CT-1 power cord (magnetic conduction). That's why it's so difficult to do a comparison to HFC products.
Just telling it like it is for those readers that are unaware.

Hi lak,

So are you saying there is no way to do a fair comparison test with HF cables? We have only tested 300 plus different cable models, not brands but cable models. I think we can figure out how to do this comparison properly. We understand that no test is perfect but testing cables is not super complicated. Ideally we would like 24 hours between moving a cable and listening to a cable but that will not be possible and neither is it with most cables that are reviewed in a comparison test. There will be 6 open minded people at the listening session and we are all very experienced when it comes to evaluating cables. Some times it just comes downs to different flavors, sometimes it comes down to where each cable has their own strengths/weakness and other times there is just a clear all around winner.

Cheers,

lak..during my/our recent testing I noticed  no significant musical change during my changing my CT-1 in and out during the testing. maybe minor..but none that would significantly throw off the sonic signature of the cable during the test..Just saying..
