[Twin JFET | 2 Transistors per Channel] JFET has high input impedance and rich and mellow sound like the vacuum tube. And the S17 Pro's Twin JFET is more than that - same temperature rises, same performances and stable mid-point voltage. It is 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 7.5W. It can drive all kinds of headphones and IEMs with ease.
[Class-A, 2 Levels of Current/Gain] 50mA/100mA per transistor; each channel has 2 pairs of transistors in parallel, so the quiescent current of each channel is as high as 100mA/200mA. 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 7.5W 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. High control precision, great channel balance, wide soundstage, accurate positioning. | The components are high-quality and carefully selected, such as the electrolytic capacitors, the ceramic capacitors, the organic thin-film capacitors, the communication-grade PCB, etc. Everything is aimed at good sound.
[2 Colors to Present Current Level/Temperature | Overheat Protection | 3-Dimensional Cooler Structure] 100mA mode is a high current Class A operation mode, similar to the GT mode in a racing car. There will be a slow temperature rise. (If the headphone impedance is low, it can lead to a faster temperature rise.) When the device temperature reaches 69°C, due to overheat protection, the S17 Pro will auto switch to 50mA Class A current mode which still maintains very good sound quality.
Powerful and Rich-Sounding | Aesthetic Tuning The S17 Pro uses the 50W 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 19200μF capacitor array. They together make the S17 Pro so powerful and rich-sounding. | The tuning is based on real instrument sounds and music pieces referencing, leading to the signature that is natural and full of musicality.
