This machine is referenced from the classic famous machine MARK LEVINSON mark pre-stage line JC-2. This machine circuit is full symmetrical field effect tube FET input, the voltage level reaches 20MA-25MA class A output, the field effect tube model is Toshiba K170BL/J74BL, this The sound of the phone is mellow and listenable, delicate and crystal clear. It is not comparable to OPA627 637. The balance is very good. It is very close to the style of the tube amplifier. The cost performance is very high. Because it is a flat symmetrical structure, you can not use input and output capacitors.
The line of this machine adds a current output stage on the original basis, which can output a larger current, suitable for use with any fever amplifier, and even can be used as an amp!
This machine has an overall layout according to the modern fever concept. Each channel is independently powered.
Specific parameters:
Frequency response: 20HZ-45KHZ
Input sensitivity: 200MV
Signal to noise ratio: 103DB
Size: width 330X height 62X depth 308mm
Weight: 4.2KG
Note: There are 8 golden German ROE capacitors in the picture, which sound is very good. However, because this capacitor has been discontinued, they are disassembly from the used board. but they works in good performance.
