What grounding does, and what it does not
Grounding products give noise somewhere to go. They connect to the earth points, unused inputs or chassis of your equipment and draw high frequency noise away to a separate box or termination. This is a signal level treatment, which is why it sits in Hi-Fi Essentials rather than under Power.
Be clear about what it is not. A grounding box is not a mains conditioner, does not filter the incoming supply, and is not a substitute for sorting out a genuine earth loop. If you have audible hum, find the loop first. Grounding products address the noise floor, not faults.
Opinion divides sharply here and we will not pretend otherwise. Listeners who report a difference usually describe a quieter background and more separation between instruments rather than a change in tonal balance, and the effect tends to be more noticeable on systems with several digital components sharing a rack. If you are curious, start with one connection to the component you suspect is noisiest and add from there rather than treating everything at once.

£187.50Ex. VATGamma ground cables use 10-gauge VTX copper conductors to reduce chassis-borne noise and boost performance. When connected to Altaira hubs or GPNR power distributors, they deliver clearer sound and video with improved dynamics, bass, and harmonic detail. Many systems achieve the full benefits of Shunyata grounding with these cables alone. -
£250.00Ex. VATThe Shunyata Research Theta Ground Cable uses heavier 8-gauge VTX™ conductors to lower impedance and improve noise reduction, delivering enhanced silence, dynamics, and timing. Featuring ArNi® wire, OFE C10100 copper, aerospace-grade fluorocarbon dielectrics, and KPIP v2™ processing, it ensures remarkable resolution and lifelike sound. With STIS™ v3 interchangeable terminals for flexibility and durability, upgrading to a Theta Ground Cable provides a powerful step forward in audio system performance.

£1,041.67Ex. VATOmega-X ground cables redefine performance with dual TAPc and CMode modules, 6-gauge VTX-Ag conductors, and an 8-day KPIP v2 treatment. This advanced design dramatically lowers noise, enhances resolution, and uncovers hidden detail. Featuring silver-copper hybrid conductors, fluorocarbon dielectrics, and gold-plated STIS v3 terminals, Omega-X delivers a powerful combination of clarity, dynamics, and realism. For those seeking to experience the full potential of their Altaira grounding hub, Omega-X is the definitive upgrade.

£450.00Ex. VATThe Max T Tuss Kit lets you connect Max T directly to your audio components via RCA, unlocking greater energy, drive, and detail. Including the Max T and two Tuss adapters (Copper and Silver), it reduces EMI and RFI for cleaner, more dynamic sound. Designed for easy integration, it offers a straightforward way to experience Max T’s powerful influence and elevate your listening experience. -
From£40.83Ex. VATThe AudioQuest Black Hole GroundGoody is an RF-dissipating ground wire using direction-controlled 6% silver over Long-Grain Copper conductors and a Carbon RF-Trap to eliminate hum and reduce high-frequency noise in turntable and audio systems. -
From£82.50Ex. VATFeaturing Solid 6% Silver conductors and RF/ND-Tech, ThunderBird GroundGoody can be combined with nearly any analog interconnect cable to create a low-distortion phono cable. -
From£165.83Ex. VATThe AudioQuest Dragon GroundGoody is a premium RF-dissipating ground wire which uses solid silver conductors, direction-controlled geometry, and patented RF/ND-Tech noise cancellation to eliminate hum and interference in turntable and audio systems. -
NEW£216.67Ex. VATThe Entreq Micro Kit Tungsten is a grounding kit comprising a Micro Tungsten ground box and a 1.1m ground cable, offering a cost-effective introduction to Entreq system grounding. Connected to a single source or amplifier, it draws accumulated electrical noise into its tungsten-enhanced mineral mix for a lower noise floor and a cleaner, more natural sound. The cable is available with RCA, XLR, USB, RJ45 or Spade termination to suit the component.

Entreq Macro Kit Tungsten - Ground Box and CableSKU: Entreq Macro Kit Tungsten - Ground Box and Cable
£383.33Ex. VATThe Entreq Macro Box Tungsten Kit is a complete single-component grounding solution for a source or amplifier, now built with Entreq's Tungsten Inside technology. It draws accumulated electrical noise out of the connected component and into its mineral-filled cell, lowering the noise floor for a clearer, more natural sound. The kit includes a hand-finished oak ground box, a 1.1m Eartha cable and an RCA click-on adaptor, ready to use straight away. -

Entreq Macro Kit Tungsten Twin Kit - Ground Boxes and CablesSKU: Entreq Macro Kit Tungsten Twin Kit - Ground Boxes and Cables
£716.67Ex. VATThe Entreq Macro Box Tungsten Twin Kit provides complete negative speaker terminal grounding for a stereo amplifier, using two independent Macro Box Tungsten units, one per channel. Each box drains accumulated electrical noise from its channel into a tungsten-enhanced mineral mix, lowering the noise floor and opening up the soundstage. The kit includes two hand-finished oak ground boxes and two 1.1m Eartha cables, ready to connect. -
NEW£1,833.33Ex. VATThe Entreq Silver Tellus Tungsten is a two-chamber grounding box, the completely redesigned successor to Entreq's best-selling Silver Tellus. Its two separate chambers give four copper binding posts in total, letting analogue and digital sources be grounded independently rather than sharing a single cell. It uses the tungsten and titanium mineral mix from Entreq's Olympus Tungsten range and includes custom aluminium spikes. -
NEW£216.67Ex. VATThe Entreq Max S is a reference point post that screws onto a Corepoint Signal or Corepoint Power unit, or an Entreq ground box, in place of the standard wooden cap. Built from three active materials, silver, tungsten and mu-metal, in a wooden body, it is designed to influence the electromagnetic behaviour at that connection point. Installation is simple: unscrew the existing cap and screw the Max S on in its place.
