The CAD Audio USB Cables

The CAD Audio USB Cables are optimised specifically for audio use in conjunction with a USB Digital to Analogue Converter.

Compared to purely analogue devices (e.g. turntables), digital audio source components produce more high frequency “noise” (EMI/RFI). This is generated within CPUs, chipsets, switch mode power supplies and regulators and so on. Also the basic USB carrier frequency can be in the 200 MHz to 400MHz frequency range. Digital audio interconnects have a range of issues that are significantly different from analogue audio interconnects. During listening tests we found that when we reduced the amount of this “noise” from reaching the Digital to Analogue Converter (DAC), sound quality dramatically improved in our opinion.

Less noise, more music: Computer Audio Design (CAD) introduces new GC3 Ground Control, three times the size of the original GC1

The new GC3 is built on identical principles but, as the name suggests, is three times the size.

CAD’s GC1 and GC3 Ground Controls are specifically designed to target high frequency noise on signal ground and mains earth, substantially reducing noise from the very high kHz range up to over 10 GHz.

Computer Audio Design is a small London based company with a quest to get the best possible sound out of digital audio. Designer Scott Berry is a hair shirt sporting purist, a state of affairs made explicit by his 1543 MkII DAC which has only one input and one pair of outputs (USB and RCA respectively), the mains cable is a heavyweight, inflexible affair that is captive – you cannot disconnect it from the DAC – and the case is made entirely out of acrylic. As a result the CAD is among the most natural, effortless sounding digital to analogue converters on the planet. But that’s not enough for Scott, he realises that the enemy of high resolution is noise, not the cars driving by outside but noise coming from the mains and from other audio components. He’s right, the less noise there is floating around a system the quieter the background to the sound and the more you can hear, it’s what differentiates the great from the good in all forms of electronics.

Over the past 10+ years the amount of high frequency noise on our Mains power has increased dramatically due to the use of computers, routers, modems, wifi, switch mode power supplies, etc. The high frequency noise that is generated within our audio systems has also increased: DACs, Servers, Computers, NAS drives, Routers, WiFi, etc. are all connected directly to our audio systems.
