In the first review of our new USBe Perfect in they summed with:

"The Core Power Technologies USBe Perfect is a revelation. The improvements are absolute. This is not snake oil audio fans, never have I heard such a noticeable improvement in an electronic add-on device. What is happening inside the screw-sealed metal container is a positive auditory experience.  The semantic terms of what the USBe Perfect does may sound cliche: removing the veil, peeling away the layers, removing the film, washing away the haze. All of the above apply and for good reason, it truly makes the music sound cleaner, clearer, more natural. Not only is this diminutive wonder not leaving my system, but I’m planning on buying a second for my other system, the USBe Perfect is absolutely worth every penny! "

Here is a dealers feedback who bought our power Diamond and Diamond Xtreme power cords:
Walter, I have been in this hobby since 1970 and a
dealer for certain products since the late 1990's. I have had many different power cords with great results, but I never thought I could get the performance that are offered by your cords at the prices you offer. I feel they are equal to cords costing at least 5 or more times. I have not had the opportunity to try all that is out there and could not afford some even at dealer pricing. I have done preliminary listening with all of your cords in my system and I am utterly amazed. I do not know how you do it, but I am a believer. At this point I do not need to go to any other cords. Cannot wait to hear what the Equi=Core and Deep=Core will offer. I will talk to my customers and local audio friends.
