Complete full DC, and complete, fully balanced amplifier with no negative feedback, made possible by our innovative technology.
exceptionally high in transparency, low in colouration
TBC-Zero has achieved a truly natural sound.
Eradication of sound deterioration factors
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 non-feedback amplifier. This results in no group delay from DC to 500kHz 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
