The CAD Ground Controls Less noise. More Music.

“Now that I’ve lived with the CAD [Ground Controls] for another couple of months, I can render my verdict : I can’t live without it. After listening for weeks, I pulled it out of my system, listened for a few minutes, put it all back immediately, then wrote a check” – Michael Fremer, Analog Corner, Stereophile

There was considerably more detail on offer and in that respect the upgrade was of a similar level to an upgrade of a streamer, DAC, preamp or other key component. But more importantly, it all just sounded much more musical, and has encouraged me to spend more time listening. Paul G, London, UK
I hooked the GC1 Ground Control up to the Melco server via the ground post and WOW, did it smooth and clean the sound up.  Just an amazing improvement in the overall quality of sound.  I’m amazed by how the stereo sounds with the GC1…Simply fantastic!!  Frank Goldfarb – Owner of Cane Creek Audio, North Carolina, USA

I just wanted to tell you about an interesting revelation I had during my last recording with Ilonka Kolthof on piccolo flute and Raloh van Raat on piano. I was really afraid of the piccolo, being such an extremely high-pitched instrument, getting super sharp and brittle, especially with my very broadband microphones. But it really wasn’t, which surprised me greatly. I then unplugged the CAD GC1 and oh my, what a difference! Of course, I had already experienced the difference the GC units can make, but I was floored by the sheer difference between having it plugged in vs not. It was incredible. My assistant engineer, who’s worked for Channel Classics and Pentatone Classics as well, said he never heard anything like it and also wants to purchase a unit.  Brendon Heinst – Recording & Mastering engineer, https://trptk.com

The GC1 Ground Control received the Recommended Product Award from Net Audio Magazine in Japan:

“I connected the GC1 to a RCA coaxial digital input of my SACD player to see how it would work. The result was an outstanding change in sound quality, noise was reduced, more details were heard, especially in reproducing weak notes. I haven’t experienced such a significant noise reduction with any other audio accessory in the past.”  Net Audio Magazine, Japan (translated from Japanese)

“Connected the GC1 to the SPDIF on my CD player, it’s so good it’s overwhelming!  Totally transformed my system.”  Alester Kells, Designer at Quadraspire audio racks

“The difference the Ground Controls make is so profound in my system – a system that already has a fully realized, dedicated AC supply and two parallel clean grounds – that they have become indispensable.”   HiFi+ Magazine

“I’m loving it – tunes are so much easier to follow and bass is so much more detailed; timing is incredible. Everything hangs together in a much more coherent fashion; every aspect of the performance is improved. The system is starting to take on some of the dynamics of real music.  Really shocking. In summary, all I can say is ‘wow’!!”   Evan S. – Massachusetts, USA

“I have one GC1 for a test in our home, I must say it is like the Holy Grail for me!  I have been looking for this solution for thirty years! And now I have found it! Remarkable, I nearly can’t believe it.”   Rickard S. – Stockholm, Sweden

“I have wired up the GC3 Ground Control and all I can say is Holy ****!”  Nick S. – Hong Kong

“WOW the improvement was astonishing.  If I had not heard it I would never have believed the improvement this little box can make” Philip – United Kingdom

“If I’m honest, I get slightly cold feet with stuff like this, as I’m not exactly wealthy and I start to try to justify spending $$$$ on a small black box? ( I’d never even try justifying it to my wife ! ) Then I listen to what it does and there’s just no getting away from it.” Stuart – United Kingdom

Features

• The new cable uses a conductor that is manufactured entirely to our specification in one location. Previously, we processed metal in several stages using a variety of small UK manufacturers.
• The purity and level of oxygen of the conductor material is significantly improved over what we used in our previous Ground Control cables.
• The new conductor goes through a substantially different annealing process.
• The new conductor is 35% larger in diameter.
• We are still using a black cotton outer braid on the cable, but it is heavier and of a larger diameter.
• The new cable is now 1.5 meters long – about 8 cm longer than the previous.
• All 4mm banana connectors that plug into the Ground Controls have a gray heat shrink while the opposite end has remained black.
• All connectors besides the spade are the same as the previous cable.
• We now offer an HDMI connector.
