 Premium Quality Components

The components used in the DA100 Signature are true high-end audiophile grade.  
Premium chipsets include the digital receiver,  24 bit / 192 kHz upsampling chip and 
the digital-to-analog converter, with 120 dB dynamic range. 
Superior quality audio playback is further guaranteed by the use of premium quality 
passive components throughout,  including WIMA polypropylene capacitors and 1% 
tolerance resistors.  Enhanced longevity is made possible by specially-selected 
gold-plated RCA connectors and low-noise switches. 
All internal parts exceed industrial standards.  Look carefully inside the DA100 
Signature and you will easily discover why this unit sounds so amazing. 

Oversized Power Supply

A generous power supply is the heart of every great-sounding audio component.  The 
DA100 Signature's power supply is specially designed, with a 25 VA custom-made 
Toroidal power transformer providing an ample supply of energy for digital and 
analog circuitry in the DA100 Signature.  The voltage regulation circuit has very low 
output impedance (20 m

Ω

@10 Khz).  Extremely stable voltages combined with 

instantaneous current delivery mean ultra-low residual noise in the Signature's output. 
This translates to silent sonic backgrounds and lifelike musical details.

You can easily change supply voltage by selecting the proper one with 
the slide switch,  located on upper left-hand corner on the main pcb.  From 100~120 V 
to 220~240 V / 50~60 Hz,  you can use DA100 Signature anywhere in the world.

Analog Output Stage

Fully Class A push-pull throughout, the analog output stage of the DA100 Signature is 
a current-based amplifier design,  for virtual immunity to electrical noise induced by 
adjacent circuitry.  This results in extremely high signal-to-noise and dynamic range 
specifications,  among the best in the world.  Voltage conversion takes place in the 
final stages of the circuit for maximum sonic transparency.
