TEQ-Zero/EX
Complete full DC, complete fully balanced, CR type phono equalizer amplifier with no negative feedback, made possible by our innovative technology
exceptionally high in transparency, low in colouration
TEQ-Zero has achieved a truly natural sound.
 
Product Features

Eradication of sound deterioration factors
Complete full DC, complete fully balanced, CR type phono equalizer amplifier with no negative feedback
TEQ-Zero can faithfully reproduce wide dynamic range and high resolution of analogue discs without colouration.
No emitter resistors
Revolutionary circuit technology that guarantees stable operation without any emitter resistors*
Specially developed duplex temperature compensation Meticulously tested and matched transistors


Newly developed differential DC servo circuit
The circuit with a flat response from DC to high frequencies assures a stable operation of the zero-feedback amplifier. This results in no group delay from DC to 100kHz and high coherency.

Large-capacity power circuit
Specially developed hand-wound flat-coil transformers with EI core that have very low magnetic flux density

Ideal chassis design and component composition

Painstaking arrangement of components and wiring for the elimination of noise and vibration
