Fully balanced design built by discrete analog stages without any
OPA or coupling caps in the signal channels.
Non- feedback ACSS analog output stage .
Uses three R-core transformers (135W total), separate power supplies
for the digital components, right and left channels.
More than 50,000uf audio grade NOVER capacitors are used to ensure
ample and smooth power supply.
A total of 9 groups class A PSU's are used to purify the power
supply. To achieve a high S/N ratio, the control circuit is powered with
Uses high-grade parts and exactly matched transistors.
Four channel 99 steps digitally controlled relay-based volume
control avoids channel imbalance and improves sound quality.
