“Passive earth or grounding systems are fast gaining traction in audio, but few can muster quite the same gavitas – or, for that matter, gravitational pull – as the top ground Control Refrence (GC-R) model from Computer Audio Design,” says Hi-Fi Plus in its special annual awards issue.
Computer Audio Design (CAD)’s system grounding unit – the Ground Control – clearly shows how fundamental your grounding arrangements can be to hearing what your system is truly capable of. Stereophile’s Michael Fremer and Jim Austin discover this for themselves, as the magazine releases its 2020 Product of the Year Awards.

In July, Hi-Fi Plus published a glowing review of Computer Audio Design’s Ground Control Reference (GC-R) system grounding unit. In the August issue, its creator, Scott Berry, answers questions about the impact of high frequency noise on audio systems and why addressing it can make such an audible difference.
Reviewer Roy Gregory isn’t known to mince his words, so if the claims of a hi-fi accessory are to be put to the test, you can count on him to tell the snake oil from the real deal. So how about Computer Audio Design’s GC-R system grounding unit? “I am saying that optimizing your grounding arrangements is fundamental to hearing what your system is capable of – and getting the benefit you’ve already paid for,” writes Gregory in the July issue of Hi-Fi Plus. “You should hear the GC-R in action. It’s musical benefits are kind of hard to ignore.” Continue reading “A huge step up”: Hi-Fi Plus reviews Computer Audio Design’s GC-R system grounding unit
“The most engaging to-die-for sound I’ve had the pleasure of hearing for some time,” says reviewer Jason Kennedy of the Computer Audio Design CAT (or Computer Audio Transport). “The CAT is obviously a superb digital source and one of the finest I’ve yet encountered… you want to use it all the time because it’s so quiet and revealing.”
“Beyond optimising for characteristic impedance, there would seem to be little point in making fancy USB cables… so how can a 1.1m USB cable costing £600 possibly offer any improvement?” wonders Andrew Harrison in the latest issue of Hi-Fi Critic as he makes a start on reviewing Computer Audio Design’s (CAD) USB Cables I & II. Some serious listening and a few hundred words later, Harrison is firmly convinced. “The improvements were clear as day.” Continue reading “Computer Audio Design re-invents the USB cable” – and Hi-Fi Critic is seriously impressed with the sonic results
It’s that time of year again folks… when hi-fi’s greatest hitters from around the globe flock to the world’s largest audio exhibition. Yes music lovers, High End Munich 2018 is almost upon us. So, just before I get packing, here are some of the highlights I’ll be heading for.
In the world of analogue audio, there’s little doubt that a system’s sonic performance can be markedly constrained or improved by the quality of its various cables. But when it comes to digital audio, could there be even more to play for? Computer Audio Design’s (CAD) Scott Berry believes so, and has been putting his ideas to the test for some time before bringing two exceptional new USB interconnects to market.
“For years, one of the best-kept secrets in hi-fi has been that the single most cost-effective upgrade you can make to any system (regardless of price or ambition) is to provide it with a dedicated AC supply equipped with a parallel, clean ground,” writes Gregory. “That might seem like a bold statement,” he acknowledges, “but consider the issues for a moment and the logic is unassailable.” Indeed it is, when we consider that the AC supply is basically the raw material from which our systems are striving to recreate the musical performance, while at the same time providing the sink down which all unwanted electrical noise is supposed to drain. “Which leads us directly to the crucial question of noise floor….”
