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.
The Ground Controls provide an effective sink for high frequency noise, which is absorbed
and converted to heat, resulting in a reduction of noise in your audio components. Their
methods of doing so borrow technology from the aerospace and telecoms industries,
combining proprietary materials in an ultra-precise internal construction. Considerable
attention has equally been given to the GC cables and connectors in order to maximize the
absorption of high frequency noise.
CAD’s Ground Controls can be connected to any audio component that has an unused input
or output connection. Whether a DAC, streamer, computer, CD Player, NAS, router, phono
stage, preamplifier, amplifier, etc – if it has a spare input or output connector (RCA, XLR,
spade, USB or Ethernet) then you can plug in the Ground Controls whose sleek, hyperminimalist
design will fit discreetly into your system.
Like the GC1, the GC3 can also be connected to mains earth, the results of which can be
breathtaking. While the GC1 has two connectors – allowing you to hook up two components,
to use both connectors for a single component or to daisy chain more than one GC1 to a
single component – the GC3 sports six, allowing multiple components to form a common
‘star’ earth connection.
An obvious upgrade
“The benefits are more obvious than you might think,” says Berry, who enjoys nothing more
than watching jaws drop at the audible difference in sound quality. “You’ll certainly hear a
difference,” he ventures, “but the degree of difference will depend on how you use the Ground
Controls in your system.” Experience has shown that the best results are often achieved by
connecting a Ground Control to the noisiest device in your system – typically a digital
component. But the possibilities are many and varied, which is why Berry actively encourages
experimentation.
The impact can be a significant drop in the noise floor, which means that every element of the
musical performance can reveal so much more. Expect liberated dynamics and a sharpening
of pace, rhythm and timing. The soundstage becomes both wider and deeper, with a natural
sense of presence. Toning is more truthful, such that voices and instruments become more
distinct and authentic. And of course the background silence is that much more silent,
enabling far greater separation, clarity, colour and texture.
