LESS HD8 Single End HEADPHONE AMP.

Portable full discrete single end amplifier

Introduce:
Less HD8 full discrete single end amplifier suitable for portable Hi-End user,design base on the sounds natural,and hi dynamic .
HD8 is base on Marantz classic HDAM circuit to modify ,increase all the transter idle current and output power,and push the circuit working on class A operation,make the output voltage more stable,
Line amp first step using Hi-End twins JFET 2SK389BL,keep the high quality preformance.
HD8 output stage using Marantz SA3 Mirror Buffer amplifier,2SB139/140 is the power output transter ,they workong on class A operation too.
