Fully balanced design built by discrete analog stages without any OPA and coupling caps in the signal channels.
Non- feedback ACSS analog output stage.
R-core transformers. 
Total of 7-groups dedicated power circuits and more than 38,000UF caps are used to purify the power supply. 
Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. 
80 steps volume level control in both high gain mode and low gain mode. 160-step volume control ensures smooth control of the volume level.
