We achieved a landmark with the Luminist 30th Anniversary, but we wanted more detail, more dynamics, and more transparency. So we set our 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. We advanced the dielectric for the separate data and power lines. In addition, we 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!

Hi Fi + Review Extract - Nicholas Rigby:

"One of the great criticisms of USB (by the CD and the UPnP streaming communities) is that the sound lacks ‘body’ or ‘weight.’ These people have never heard what the Purist Audio Design 30th Anniversary USB cable can do! The overall sound with this cable is just the right side of ‘dark’ to be full of musical gravitas rather than ‘moody’, and is also powerful, weighty, and monumental when it needs to be. Even when moving from sweeping Sibelius to bouncy Brubeck, the overarching impression is one of detail coupled with solidity of instruments and players."

"Yet, for all this weight and solidity, the Purist cable wants for nothing in terms of soundstage retrieval and detail; and detail across the board, too. The high frequencies had none of that quasi-artificial ‘high-end shimmer’ (which is, in fact, often inaccurate note decay), but instead revealed the nature of the recording right down to the reverb tails on background instruments. Mids had the same accuracy, and bass lines were full and yet tight and taut when needed. In short, this is about as good as it gets! "

"Purist Audio Design’s 30th Anniversary is a year of great maturity and extremely good products, if the USB cable is anything to go by. This is a cable that does all the right things for computer music. Very highly recommended."

The Part Time Audiophile Review:

The problem this stance had to overcome was born of pure experiential data. In short, I tried this cable out on many people. That is, I was pretending to screw around with “something” in the system while swapping only this cable in and out. Over the course of a year, I did this with dozens of people.

Over the course of my “testing”, there were several cables that met with acclaim, but only a very few that folks were able to agree were “the best”. The Diamond Revision 30th Anniversary USB was the best of that group – best improvement to the sound and the easiest to use.

By “improvement”, I mean something like “ease”. That is, there is an easing to the sound when good digital cables are used. Some folks say that this is a lack of edginess, an analog type of smoothing, a removal of something inherent in digital playback that puts your teeth on edge. I don’t necessarily agree – there is nothing lost with the Purist USB. Quite the opposite. Instead, I have that same effect I get with the ZENith server – a sense of relaxation, like the difference between a warmed-up band playing their favorite hits and that same band exploring a brand new tune. Perhaps it’s better to say that it’s as if there’s a fullness to the sound, a wider envelope, more comfort. I tend to call this phenomenon as “organic”, because it puts me in mind of the difference between skin seen with the eye and skin seen under the hand. There’s just something different to being physically and immediately present that photography abstracts you from. I suppose that might mean a timbral fullness, a fuller spectrum of transmission, but I suspect the numbers there would be inconclusive. Instead, I think the closest physical analog I can make is the difference between an amp with a “proper”, fully-spec’d out, well-designed power supply, and one that is “overbuilt”. Border Patrol amps are like this – you can get one of their power amps with the “proper supply”, and that sound will be heaven wrapped in silk. And then, when you’re ready, you can upgrade that “proper supply”, and begin to enjoy those “wait, what just happened” experiences. And then, when you’re ready, you can upgrade the upgrade, and have those “uncontrollable giggling” episodes that may require pharmaceutical intervention to control. Great cables are very much like this. Shouldn’t matter! The first damn wire was “built to spec” and everything else should be unnecessary, a technical gilding of the lily. But the giggle is right there, nonetheless, mockingly reaching out to fondle your goose bumps as you sit there, paralysed, saying “See? I told you so.”

"The Purist Audio Design Diamond Revision 30th Anniversary USB is now my reference."
