Modern and vintage harmonize design

The design motive from the classic gramophone. Horn type tweeter, retro speaker grill design and the amplifier with vintage vacuum tube. This design gives you the special and retro romantic feelings and bring it back to today’s life.

Customized hybrid vacuum tube

VACUUM TUBE Customized hybrid vacuum tube

The quality of LANCHIYA® customized vacuum tubes for the new hybrid amplifiers is the same as what the military industrial enterprise requests. We take the advantage of the even harmonics to enhance the dynamic range and the frequency response of the sound. The tubes can make the sound mellow and charming. The life of the tubes is about 50,000 hours.

Advanced DSP sound technology E.A.I bass technology

EAI / iEAI Advanced DSP sound technology E.A.I bass technology

LANCHIYA®EAI™ (Electronics&Acoustics Integration) chip module to make the electronics, speaker drivers and housing structure match each other perfectly so that the whole speaker system can perform at its best status and produce the best sound.  With the help of DSP to correct the input signal in a nondestructive way , the whole speaker system can perform beyond its physical limitation.    

Experience our audio technology taken to new heights with E.A.I & Digital Sound Processing (DSP) Fine-tuned for perfection maximum power generated from its two 0.8” silk dome tweeters, two 2 ¼” active wide frequency response speaker driver units.

Advanced 2nd generation T.B.B Sound technology

TAIKO BASS BOOSTER™ (Invention patent) 

TAIKO Bass Booster™ is a low frequency multiplication technology which is painstakingly invented by LANCHIYA®'s R&D team after seven years' reseach and study. It's a revolutionary and innovative new technology of electro acoustics,which combines LANCHIYA®'s patent technology of double resonators and EAI™(Electronics Acoustics Integration System) It can multiply the power of low frequency in a small speaker housing. Even the volume is very small, it still can make the speaker produce the clear, powerful and elastic bass. This technology reflects LANCHIYA®'s persevering spirit of  pursueing the Hi-Fi sound quality.


The tweeter used to reach to 15-20kHz. But Lanchiya R&D team is willing to make it reach up to 28kHz with their 36 years experience. The advanced silk dome tweeter which imported from Japan will be used for the amplifier. The perfect tweeter can be presented based on the perfect match by the tubes and the amplifier.

Minimum diffraction horn type tweeter for natural sound reproduction. We take the advantage of the horn type structure to enhance high frequency up to 28KHz. Make the sound levels and the sound field more clear. The horn type tweeter can reproduce high frequency with more fidelity and decrease the sound diffraction.


3Way 3Speaker design and professional cross-over network design

two 0.8” silk dome tweeters, two 2 ¼” active wide frequency response speaker driver units, two 2 ¼” active bass frequency response speaker driver units with professional cross-over network design

Headphone amplifier 

Built-in High performance vacuum tube headphone amplifier

The headphone amplifier can drive the headphone impedances from 32Ω to 600Ω by the advanced automatic impedance matching system. Its power is 7W. It can support all of the audio formats by the high performance of the hardware decoder. It’s compatible with DSD256, DSD128 and DSD64. Including PCM 32bit 384kHz. The vacuum tubes are used for adjusting the sound. The external sound output and the internal decode input can be freely switched.

Intuitional user control interface

A rotating knob for functional control ( OFF- Bluetooth-AUX-Phono-PC USB) and a rotating knob for volume control. Aluminium control switches for the sound effect function and the headphone amplifier select.It is about the useful and intuitional user control interface design.
