I have not posted here for some time.  However, I came cross a new cable design that may be of interest to the digital community, which is my main focus.


Background: I have horrible electrical power in part due to the tech neighborhood I live in (high concentration Nike and Intel Exec) and the switch power supplies in my house played havoc on my system. I installed a Torus 75a isolation transformer and ran dedicated lines. Tore the darn house apart in the process. The wife was pissed. I have dedicated lines to each Amp, Pre, and source components feed off a Audience Adept Response TSSD 12. I replaced my au24sx power cable with the ZL5000 to a Neutrik adapter. The improvement was not subtle, particularly in the detail of music presentation. I had more spatial clarity and hear level of detail in my music that was not there before. ZL cables are welded. Once they can do this process to a Neutrik I will replace the cable without an adaptor.

These cables across the product line have done a tremendous job at removing RF pollution which I still struggles with despite the isolation transformer, LED lighting and Dimer switches. Between my rack and amps, in the corner is a gas stove. The fan when clicking on and off would create a pop in my speakers. More so with the 99 dB effeciency. The pop was loud. Even tried at the advice of Steve Nugent at Empirical, place a capacitor between the hot and neutral of the motor ac plug to no effect. These cables silenced this. Only if I place my ear to the speaker I can hear a faint pop. It is effectively gone a 1' from the speaker, vs being significantly annoying. 

From another customer that posted on Audioshark: "Not only did the system get quieter with the power cable but the bass is more taut and textured. Sense of space is better. I'm also hearing micro details that I've never heard before on well known albums, even when previously played with higher priced components in former systems. Overall, one of the better upgrades I have done $ for $. "

Kang Su Park who is the lead designer and owner of Allnic Audio developed a cable company, ZL Technologies.


After much dialog with David Beetles and Kang Su, my conclusion is that ZL5000 vs ZL 3000 cables are identical except for the gauge of the wire. The rule is for low current demand use the smaller gauge ZL3000. However, this rule in my estimation has been debunked. High current linear power supplies for source components is essential to reduce jitter and meet the demands for optimal signal presentation. I challenged both of them to a comparison and another person who also has replaced his cabling across all his systems with ZL. They had an eye opening moment. The consumer who I modeled my system from in 2012. Sold off all his ZL3000 for the 5000 series. The cable is much stiffer but manageable. My wife is more OCD than I am. She re-laid my cables maintaining my one rule that signal cables are above power cords. While stiff, it is doable.

I personally have had a very long journey in the cable world with some good investments and some horrible ones. These cables are worth your attention. While this review stated great benefit with one cable. This becomes vastly understated when you replace all the cables in your system. The more I purchased the deeper the discount I was offered by David Beetles of Hammertone.

I have one to offer to try if interested, but Hammertone offers a no risk purchase - just return in a resealable condition. 

Additional lengths are of nominal costs. 33' unbalanced cable was custom made and fortunately not sold on a per meter basis, unlike Antipodes Reference. These cables are better and selling a 5 meter cable (maximal length by Antipodes) has proved difficult.

I strongly recommend auditioning them. The power cables are fantastic. I will trial some speaker cables in the coming months.
