When it comes to hi-fi accessories, it pays to make smart choices. There are certain products, painstakingly developed by highly skilled audio engineers, which have the potential to transform the sound of your system so dramatically that you’d be forgiven for wondering if it’s the same system. US magazine The Absolute Sound singles out several such inventions in its 2024 Buyer’s Guide.

“The sound of silence”: The Absolute Sound reviews Computer Audio Design’s GC1.1 and GC-R Reference Ground Control
“For over a decade my mantra has been to get grounded,” writes Jacob Heilbrunn in US audio magazine The Absolute Sound’s October issue. Heilbrunn has gone to far greater lengths that most to lower the noise floor in his audio system, seeking to reduce the ground resistance to as close to zero ohms as possible. So in reviewing Computer Audio Design’s (CAD) Ground Control units, could there be any further ‘ground to gain’?
“CAD drops the noise”: The Ear reviews Computer Audio Design’s USB II-R cable & filter
Computer Audio Design (CAD) was one of the first companies to see USB as the best solution for streaming hi-res audio, and company founder Scott Berry is still at the leading edge of the technology, developing ground-breaking ways to tackle unwanted noise and optimize audio performance. Jason Kennedy puts his latest duo of inventions to the test.
“Less noise, more music”: The Ear reviews CAD’s GC1.1 Ground Control
Computer Audio Design’s (CAD) Scott Berry believes that dealing with high frequency noise on the signal ground plane is critical to allowing sound systems to reach their performance potential. The sonic difference made by CAD’s GC1.1 Ground Control unit clearly proves Berry’s point, as Chris Baillie reports in The Ear.

“Kryptonite for noise”: Roy Gregory discovers the sonic powers of CAD’s USB Control
Computer Audio Design’s USB Control is a small device that works on both redundant USB inputs and service ports. It’s “about the size of (and could easily be mistaken for) a USB dongle” and is “about as discrete as an audio tweak can get,” writes Gregory. “But don’t let its diminutive dimensions or understated appearance fool you. This thing is kryptonite for the spurious noise generated by USB circuitry.”

Computer Audio Design shows Hi-Fi Plus the new CAD Computer Audio Transport
Computer Audio Design’s Computer Audio Transport (CAT) “has a degree of poise that is very rare in any form of audio source,” says Hi-Fi Plus. “It combines precision with naturalness of timbre and tone that makes acoustic sounds so real it’s uncanny. The noise floor is so low that everything you play reveals fine details that were previously masked or unclear.”

Computer Audio Design’s USB II-R USB cable “must be heard to be believed” says Hi-Fi Plus
There’s a common assumption that digital audio sent over a USB cable is bit-perfect, writes Andrew Harrison, leading to “a naïve way of viewing the value of specialised USB wiring.” The reality, however, is that “unlike the protocols used for transferring file system data, the USB audio standard has no robust error checking and correction.” Which is why a digital audio system has much to gain from advancements such as CAD’s USB II-R USB cable.
Computer Audio Design’s new USB Control: the simple, affordable solution to high frequency noise
PRESS RELEASE: Reducing unwanted high frequency noise in a hi-fi system audibly improves the system’s sound quality. Computer Audio Design (CAD) has pioneered a portfolio of highly effective solutions to the problem, and now adds the new USB Control – which also happens to be the company’s most compact and affordable solution yet.
Computer Audio Design replaces ground-breaking USB I & II Cables with new USB II-R Cable & USB Filter
PRESS RELEASE: It is widely accepted that analogue cables can have a significant impact on the sound quality of an audio system. Computer Audio Design has long believed that digital cabling has at least the same impact. The company’s unique – and astonishingly effective – digital interconnects continue to prove their point, and are now further enhanced for an even more audible impact.
Computer Audio Design’s Ground Control GC1.1: “once you hook it up, I doubt very much you’ll want to remove it” says Roy Gregory
Audio reviewer Roy Gregory was an early adopter of Computer Audio Design’s Ground Control units, designed to improve system performance by tackling high frequency noise on the signal ground plane. In a recent review he asks, “What does the new, updated and improved GC1.1 bring to the party?” Continue reading Computer Audio Design’s Ground Control GC1.1: “once you hook it up, I doubt very much you’ll want to remove it” says Roy Gregory
