ASUS Essence 3
DESIGN HIGHLIGHTS
Hardware highlights
Power management
• Independent L/R Power Supply
With perfectly balanced L/R power supply, this minimizes power outage and ripples, hence reducing cross talk.
• High-fidelity Low Dropout Regulator (LDO) Regulation
Using the highly regarded (TI TPS 7A4700 and 7A3301), the power source is regulated twice to reduce heat energy
and ensure stable power.
• Hyper/Super Grounding 2oz Copper PCB Board
Unprecedented choice of material with 2oz Copper conducted 4-layer PCB board for regulating heat and energy
source.
• Robust Capacitor
WIMA FKP2 capacitor serves as a stable water reservoir for stabilizing power source, hence reducing ripples.
• Toroidal transformer
Specially designed Silicon-strip toroidal transformer to reduce hysteresis loss and prevent easy worn-out.
Signal management
• 4-Layer Hyper grounding
4 layer PCB board with extra 2oz. copper for separating Digital and Analog signals on different grounds and heat
source. Not only are the analog and digital signals on different layers, it is sandwiched in between multiple ground
layers to further prevent signal interferences.
• Perfect Isolation
Separate analog and digital signals boards (2 main boards + power board) with no cross-over layout. Even at
areas where analog meets digital signals, this area is enclosed with the shortest signal travel distance to prevent
interferences.
• Asynchronous data transfer
A PC uses a different clock system from Essence 3 and hence a buffer will monitor the data speed such that when the
PC clock is firing too fast, this is regulated and the data transfer feed is adjusted to slow down. This greatly improves
the precision of digital audio and provides more detail with less listening fatigue.
• TCXO Clock Source
Clock generators are susceptive to heat/temperature changes, which can impact the stability of audio source. Hence
with a pure-gold module acting as a clock source (normally used in GPS), this would minimize jitter and support more
stable local clock signals.
• Total Ground Isolation with 40-pin digital parallel cable
The 40-pin cable is dedicated for high-speed digital data signal transfer. Voltage changes are volatile and signal
crosstalk can increase with digital signals. To prevent this, a 40-pin parallel cable is used. All the middle paths are used
as ground ensuring a total separation and minimizing any possibility of interferences.
• High Channel Separation: 20-pin analog parallel cable for Headphone
The middle paths of the 20-pin analog parallel cable is also used for ground, and hence the left and right channels
separation would be 6 times more than the normal 3.5mm cable for headphone, perfectly balanced with super low cross
talk.
• Custom Resistor with high temperature and heat tolerance
0.1% tolerance and high tolerance for temperature changes with +/-0.5ppm/Celsius with ultra-low noise and better
stability.
• DC Servo to reducing DC biasing:
The DC servo design helps to reduce decoupling and this helps to extend bass performance with richer and deeper
sounds. The 6 Op-amps for DC servo also helps to reduce DC biasing, which causes jitter.
