TiGLON TMB-DR20E Virtual Grounded Audio Board

The TiGLON TMB-DR20E represents a masterful convergence of mechanical isolation and electromagnetic conditioning, elevating the listening experience from mere high-fidelity reproduction to profound acoustic realism. Meticulously engineered in Japan, this dual-function platform addresses the dual adversaries of high-end audio performance: structural micro-vibrations and insidious ground-plane noise. By nesting a highly purified magnesium shield within an acoustic sandwich of premium Russian birch and high-density timber, the TMB-DR20E behaves as both a sophisticated energy sink and an artificial earth reservoir. When integrated via its bespoke D-REN grounding architecture, the board strips away the microscopic electronic haze that compromises low-level detail, yielding a remarkably dark, holographic background from which the organic texture, spatial architecture, and dynamic authority of the music can fully emerge.

The TMB-DR20E is a 3-hybrid structure audio board with virtual grounding, made from the same high-grade Russian birch used in the flagship “magnesia” audio rack.

The TMB-DR20E retains the basic structure of the previous model TMB-10E, but the purity of the magnesium plate material has been further improved to enhance vibration absorption and improve sound quality. It has a three-layer hybrid structure with a top layer of high-grade Russian birch, a middle layer of the purest magnesium plate, and a bottom layer of high-density MDF.

As a technology to further improve the sound quality, we propose virtual grounding using the included magnesium shielded ground wire.
The conductor (DF-OFC) and insulator (Super Clear Isolator) used in the flagship TPL-2000RX line cable are adopted, and the outer sheath is constructed with the tuning spacer “D-REN pro” technology to further improve the vibration control effect of the wire itself. D-REN Earth, the ultimate grounding wire, was created by applying the H.S.E treatment treatment, which has become one of our representative technologies. By connecting this “D-REN Earth” between pure magnesium and the equipment used, an unprecedented sense of silence and a realistic sense of stage will spread before your eyes.
The TMB-DR20E is a product that enables two effects in one unit: tuning board and virtual earth.

About

Tiglon is a Japanese high-end audio manufacturer specializing in cables and accessories for the audiophile market. Founded by Kentaro Okino, the company's reputation is built on its innovative and patented use of magnesium, a material chosen for its superior ability to suppress vibrations and shield against electromagnetic interference (EMI).

Tiglon's philosophy is centered on the pursuit of "unknown sound" by creating accessories that reveal the natural texture and emotion of music. The company believes that by focusing on material science and vibration control, it can create products that bring "emotion and fun" to the audio experience. This is achieved by protecting the signal from external noise and interference, creating a quiet background that allows musical details to emerge naturally.

Key Innovations include: Magnesium shielding technology utilizes a patented magnesium foil to protect the cables. This material effectively absorbs vibrations and blocks EMI/RFI interference, without producing the metallic "ringing" found in copper or aluminum. The Hyper Saturated Energizer (HSE) treatment, developed in partnership with European and Asian engineers, applies programmed electrical currents to the conductor to enhance its crystal structure. This process shortens the break-in period and improves clarity, depth, and tonal balance. The D-REN sheath, initially designed for "D-REN Pro" tuning spacers, reduces micro-vibrations and static electricity, enhancing overall audio quality.
