Jim Aud from Purist Audio Design states:

Hello, I’m Jim Aud with Purist Audio Design. We’ve been manufactoring cables since 1986. We’re introducing 3 new products here, at the Munich Audio Show. The first product that we’re introducing is a brand new USB cable: the 30th anniversary Diamond revision. What’s unique about it? New connectors, metallurgy. Also, it has a special twist and new cosmetics. We’ve done comparisons with other products… cable! The second product that we’re introducing is a new AC box. It’s a six outlet, has passive filtering inside. It uses Ferox AC Tube which is either tuned to 50 or 60 cycles. It has inside aligning which blocks out RF/EMI and vibrations. The third product is for people with like Mac computers. It’s a USB C to A cable. So, for people having problems to get optimal music. It contains high quality silver wire to give you quality sound. Thank you for listening to me.

Diamond Revision 30th anniversary USB cable

Purist Audio Design has achieved a landmark with the Luminist 30th Anniversary. But they wanted more detail, more dynamics, and more transparency. So they set their engineers to work, and they dialed it up to 11! We greatly improved the passive filtering on the power conductors by using a specially tuned, hand-wound toroid. Purist advanced the dielectric for the separate data and power lines. In addition, they added sonically superior USB connectors with beautifully gold-plated housings. The sound of the Diamond Revision 30th Anniversary is breathtaking, with wonderful inner detail, amazing dynamics, and a beautiful transparency. The Diamond Revision 30th will truly bring out the music in your high resolution computer audio system!

AC Power Extension

Purist Audio Design is proud to introduce an improved AC Power Extension. This smaller unit is now available in 3 duplex (for U.S. style plugs) or 6 schuko (for European style plugs). The chassis is completely redesigned with a special aluminum alloy. We’ve added increased dampening for the chassis that limits mechanical vibration. Purist uses proprietary passive filtering to protect the sound and not interfere with it (as with some active filtering technologies). In addition, resonator tubes are utilized and these are tuned to a frequency of 50 or 60 Hz depending on country. They help to passively filter out noises generated by electricity that is flowing through the outlet and does not limit voltage or current. Yet, it eliminates noise frequencies that are beyond these cycles. The internal wiring is the same technology used in our upper line power cords. Our engineers also carefully selected, and matched Furutech Outlets and an IEC Inlet that would meet our high specifications as well as the demanding audiophile’s needs. The Purist Audio Design AC Power Extension delivers optimum performance for your prized audio system!

USB C to USB A adapter

Have a device with only USB-C ports? Purist Audio Design’s USB line now includes a USB-C to A adapter. All USB cable adapters are specifically designed for computer audio applications. Purist Audio Design builds by hand from the ground up, with low impedance and hi-quality, custom shielding. From your home server to your mobile listening station, Purist Audio Design connects you to the music and has for over 30 years.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
