A virtual earth the size of a cigar that screws or plugs straight onto the component. Ten terminations, one per socket type.
100V (Japanese voltage) — for JP-spec gear or step-down use. The essential Crystal tap: three grounded outlets, one ungrounded, and the full M.I.S. chassis treatment at the friendliest price.
100V (Japanese voltage) — for JP-spec gear or step-down use. Three grounded outlets plus a link port, built on the Crystal chassis: the expansion brick of the family.
100V (Japanese voltage) — for JP-spec gear or step-down use. Six grounded outlets plus a spare ungrounded one, in the Crystal series' damped chassis. The big-system tap.
100V (Japanese voltage) — for JP-spec gear or step-down use. Two grounded outlets plus a link port, under one proper power switch, in the Crystal series' vibration-damped chassis.
The classic KOJO virtual earth: an 8-layer dissimilar-metal stack that gives a component a proper local ground. Two leads included.
100V (Japanese voltage) — for JP-spec gear or step-down use. Surge protection plus a redesigned normal-mode noise filter that cleans the line without starving the music.
100V (Japanese voltage) — for JP-spec gear or step-down use. The Crystal 6.1's six outlets plus a real power switch: one flick takes the whole system down.
100V (Japanese voltage) — for JP-spec gear or step-down use. One inlet in, digital and analogue lines out, separately filtered: the tap that makes system power hygiene a habit.
The G-spec stick virtual earth: roughly double the standard Ep's conductor area in the same pocket format.
100V (Japanese voltage) — for JP-spec gear or step-down use. If your transformer hums, DC on the mains is the usual suspect. The H1P detects it and blocks it, with a lamp to prove it.
100V (Japanese voltage) — for JP-spec gear or step-down use. A soft-start tap that tames inrush current: gentler power-up for valve amps and vintage gear that deserves a long life.
KOJO's biggest box-type virtual earth: fine-blasted 8-layer plates plus six etched-foil capacitors for 68 times the Crystal E's area.
A virtual earth the size of a wall plug with the conductor area of a soccer field. Plugs into a spare outlet, works on the whole system.
100V (Japanese voltage) — for JP-spec gear or step-down use. KOJO's 35th-anniversary hi-end tap: four outlets, virtual-earth option socket, and a chassis built like lab equipment. 50 units worldwide.
100V (Japanese voltage) — for JP-spec gear or step-down use. The Aray's regenerator circuit at 580VA and a friendlier price, without giving up the family transparency.
100V (Japanese voltage) — for JP-spec gear or step-down use. The six-outlet anniversary tap to the Platinum4's four: same limited Jtune build, more sockets for a full system.
100V (Japanese voltage) — for JP-spec gear or step-down use. The long-running flagship regenerator: 1,000VA of rebuilt, noise-free AC that made reviewers reach for superlatives.
100V (Japanese voltage) — for JP-spec gear or step-down use. A regenerator-type clean power supply that keeps the energy your music had before the wall got involved.
100V (Japanese voltage) — for JP-spec gear or step-down use. Hand-matched IGBTs, torque-managed assembly and a 1,200VA output: the Aray taken as far as KOJO's craftsmen can take it.
100V (Japanese voltage) — for JP-spec gear or step-down use. KOJO's 35th-anniversary conditioner: virtual-earth tech, split direct/filter lines and surge protection in one wild box.
100V (Japanese voltage) — for JP-spec gear or step-down use. KOJO's flagship: a 2,500VA hybrid of regenerator speed and transformer heft, built to order like its namesake sword.
