[Twin JFET | 2 Pairs of Transistors per Channel] JFET has high input impedance and rich sound. The S17 Pro EVO’s Twin JFET is more than that - same temperature rises, same performances and stable mid-point voltage. It’s the ideal input transistor of a headphone amp. | The final output stage uses 2 pairs of output transistors in parallel. The whole device has as many as 16 output transistors. Max output is as high as 7.5 W. It can drive all kinds of headphones and IEMs with ease
[Class-A, 2 Levels of Current/Gain] 50 mA/100 mA per transistor; each channel has 2 pairs of transistors in parallel, so the quiescent current of each channel is as high as 100 mA/200 mA. The sound of a class-A amp is mellow, warm and smooth; 2 gain levels: the low gain takes advantage of the class-A amp’s feature that the transistors are always working in the linear area to drive the lEMs well and properly, while the high gain is as high as 7.5 W and thus can drive headphones well with big power
[R2R Electronic Volume Chip | Rigorous HiFi Component Selection] Uses the R2R electronic volume chip from JRC and the dedicated op-amps to build the 4-way balanced R2R volume control.

When the device temperature reaches 69 °C, due to overheat protection, the S17 Pro will auto switch to 50 mA Class A current mode which still maintains very good sound quality
Powerful and Rich-Sounding | Aesthetic Tuning The S17 Pro uses the 50 W low-ripple toroidal transformer and dual-power design. Digital control and analog are independent from each other, so the analog part can be free from interference. What’s more, it has the 19200 μF capacitor array.
