EIZZ XLR DC Input Jack

Posted by Duster on February 14, 2017 at 12:39:48:

I've been wanting to upgrade the Neutrik male XLR DC input jack of my Aragon 18K MkII preamplifier unit for quite some time now, especially after finding a product that should have been developed and marketed by Xhadow, since the design concept is theirs, but taken up by a high-quality Asian manufacturer. I read years ago that Xhadow intended to offer high-performance XLR jacks to mate with their SOTA XLR connectors, but that simply never happened.

EIZZ is a Chinese manufacturer I find to produce word-class audiophile connectors, and the cost of their products reflect the quality-level since they aren't cheap, although not particularly expensive. Definitely a high-value line of products, if not competitive with western brands at similar price points. The most attractive aspect of the EIZZ XLR jack is the massive Teflon dielectric, not unlike the massive Teflon dielectric of the Xhadow XLR connectors, which not only provides a low dielectric constant material as an electrical insulator, but also good vibration control properties vs. inferior plastics. The important conductive benefit of the design is a tellurium copper base metal contact vs. a mundane brass contact, which tends to be of very notable sonic benefit, to my ear.

In this case, the EIZZ XLR jack will be used as a DC umbilical jack between an Aragon IPS outboard power supply unit and an Aragon 18K MkII preamplifier unit. The DIY DC umbilical for the preamplifier is terminated with a female Xhadow Precision XLR connector, with improved performance vs. a gold Neutrik XLR plug. However, the Xhadow XLR has been connected to a mundane Neutrik XLR jack with questionable sound quality from the get-go. Upgrading the stock Neutrik jack with an EIZZ XLR jack should be an interesting upgrade to evaluate.
