The ACSS (Audio-gd Current Signal System) technology employed in C-2C Headphone amplifier . Previously, this technology was used only in very high-end gears of famous manufacturers. BPM-7110 module is composed of all discrete transistors; it adopts a current working style which guarantees ultra low distortion. This special technique and circuit counteract the non-linearity caused by transistor. The output signal depends entirely on the resistors in the module. The resistors used in our BPM7110 module are the expensive and accurate Israel VISHEY resistors imported from USA. This module sells for over 60,000 yen in Japan. When BPM-7110 with current technology is adopted to make headphone amplifier, the voltage gain and the volume can be synchronously adjusted. Therefore, a high SNR and a low distortion are achieved. Even with a slightly higher gain, there is no overload distortion in effective output range. 
          This circuit has exceptionally high sound restoration ability.  You can input XLR balanced signal or RCA unbalanced signal. No matter what kind of signal is input, it has the ability to transfer it to current signal and amplify it.
          The output stage is also elaborately designed. By applying cascode circuit which is combined by bi-polar transistor and FET transistor, this board not only achieves a better linearity, but also improves the driving force to a higher level than that with pure field effect transistor. Therefore, the sound delivery is more lively and enchanting.

        To achieve a better effect, C-2C also employs the complex parallel stabilized voltage supply to get a purer power supply, so that better sound quality is guaranteed. 

         C-2C uses all aluminum chassis (Black). Dimensions: width 250mm, height 75mm and depth 290mm. Panel thicknesses 8mm.

        The balanced XLR input sockets of C-2 are both expensive Neutrik products. Other sockets include RCA socket of CMC, etc. It is soldered with WBT silver solder.
