Awesome and catchy heading


VTL
VTL, Vacuum Tube Logic, builds valve amplifiers, preamplifiers and phono stages by hand in Chino, California. The lineage reaches back to the recording studio, to the playback amplifiers designed in 1980 by recording and film engineer David Manley. Since 1987 every component has left the same Californian workshop, and the name has become a byword for high-powered valve amplification.
From the control room
David Manley’s first designs had a single task: to give recording engineers the truth, session after session, without faltering. That discipline became the foundation of VTL. Production for home listening began in Britain in 1983, and the international press took notice. A visit to the Consumer Electronics Show in Chicago in 1986 carried the designs to America, and by 1987 the workshop had settled in Chino, California.

From Wotan to Lohengrin
From 1993, under Luke Manley, VTL pared the range to the high end and made power a defining trait. The Wotan MB-1250 of 1995 delivered 1,250 watts, among the most powerful valve amplifiers in continuous production. The Reference models that followed, the TL7.5 preamplifier, the Siegfried monoblocks and the S-400 stereo amplifier, pair valve audio circuits with precision-regulated power supplies and microprocessor control.
Automatic biasing of every valve holds the Reference amplifiers at their optimum without manual adjustment. The Lohengrin Reference monoblock, introduced in 2025, refines the formula: eight 6550 or KT88 output valves deliver 400 watts in tetrode or 200 watts in triode, switchable, with zero global negative feedback, multi-layered fault sensing, an adjustable damping factor and a response just 1dB down at 100kHz.
The current range spans sixteen models, from the IT-85 integrated amplifier to the Siegfried Series II and Lohengrin Reference monoblocks, with four line preamplifiers and two phono stages alongside. Every one is built by hand in Chino. Cadence Distribution represents VTL in the UK and Ireland.
