AudioQuest Black Hole Groundgoody Ground Cable - 0.75 Meter

AudioQuest Black Hole GroundGoody Fights Hum Without Acting as an Antenna

A turntable ground wire carries no audio signal at all. It connects a turntable or tonearm's chassis ground to a phono preamplifier's ground point, draining away hum a signal cable alone can't stop. A premium ground wire differs from a plain strand of wire in conductor quality and how well it dissipates radio-frequency noise.

AudioQuest built Black Hole GroundGoody to solve a problem with plain ground wires: unlike a simple strip of wire, which can act as a radio-frequency antenna, Black Hole prevents hum while efficiently dissipating radio-frequency noise instead of picking more of it up.

6% Silver Over Long-Grain Copper

AudioQuest says Black Hole GroundGoody uses premium conductor materials, 6% Silver over Long-Grain Copper, controlled for direction and cold-welded to Direct-Silver-Plated #10 size spade lugs at each end, the same termination approach used across AudioQuest's cable lines.

A Carbon RF-Trap for Extra Noise-Dissipation

Black Hole GroundGoody employs a Carbon RF-Trap made of conductive PVC, AudioQuest says, to aid its RF-Noise-Dissipation beyond what the conductor and spade lugs handle alone, so it does not act as an antenna the way a plain strip of wire can.

The Connectors, Explained

Black Hole GroundGoody terminates in a #10 size Direct-Silver-Plated spade lug at each end, sized to fit the ground posts common on most turntables and phono preamplifiers you're likely to own.

What Reviewers Are Saying

One independent reviewer at audiosciencereview.com wrote of AudioQuest's GroundGoody line, “I can objectively report that the Audioquest GroundGoody does a great job as a grounding cable and I have no audible hum.”

Who Is This Ground Wire Best For?

• Your turntable or tonearm still hums even with a signal cable connected — a dedicated ground wire like Black Hole is what actually addresses chassis hum, not the signal cable
• Your current ground wire is a plain strip of wire with no shielding of its own — Black Hole's Carbon RF-Trap is built specifically to avoid the antenna effect a plain wire can create
• Your turntable or phono stage has a spade-lug ground post — Black Hole's #10 size Direct-Silver-Plated spade lugs are sized to fit that post directly
• You want AudioQuest's direction-controlled conductor construction on a ground wire, not just a signal cable — that same approach carries over to Black Hole
• Your budget calls for AudioQuest's step-up ground wire instead — AudioQuest ThunderBird GroundGoody carries a more elaborate noise-dissipation construction at a higher price

How Does It Connect to Your System?

Connect one spade lug to your turntable or tonearm's chassis ground post, and the other spade lug to your phono preamplifier's ground terminal, alongside your regular signal cable connection.

Then power up the system as usual. Other and longer lengths available. Call for prices.

Pairs Well With

A ground wire is one link in the vinyl playback chain. It usually joins these categories.

• Turntables — the source of the signal or ground point this cable connects to
• Phono Preamplifiers — the usual destination at the other end of this cable
• Phono Cartridges — the cartridge is what actually generates the signal this cable carries
• Stereo Amplifiers — many integrated amps include a built-in phono stage of their own

Frequently Asked Questions

Do I still need a signal cable if I have this ground wire?

Yes. A ground wire carries no audio signal at all; it only drains away hum between your turntable's chassis and your phono stage's ground point. You need both a signal cable and a ground wire for a complete connection.

What does the Carbon RF-Trap do?

AudioQuest says it aids Black Hole's RF-Noise-Dissipation using conductive PVC, on top of the noise-control the 6% Silver over Long-Grain Copper conductor already provides.

Will this fit my turntable's ground post?

Black Hole terminates in a #10 size spade lug at each end, the size commonly used on turntable and phono preamplifier ground posts; check your gear's actual ground post size before ordering if you're unsure.

Is there a step up?

AudioQuest ThunderBird GroundGoody is the step up, adding AudioQuest's RF/ND-Tech noise-dissipation on top of Black Hole's construction.
