Discrete Amplifier Module for DX240 Green
iBasso unveils with the AMP8 MK2 a discrete amplifier module that can be installed on the iBasso DX240 Digital Audio Player (DAP). Its architecture uses discrete components rather than AOPs, in order to provide high output voltage and current, while maintaining a low output impedance and offering excellent measurements
The AMP8 MK2 has a voltage variation of ±8V, improving the dynamics and the headroom for a particularly precise and musical reproduction. Bipolar transistors are used and matched to ensure excellent linearity. The transistors used in the buffer stage have an output current of 2000mA, allowing the amplifier to accompany both sensitive headphones and high impedance headphones. We also find high quality ERO capacitors participating in the high quality of sound restitution of the AMP8 MK2.
Finally, the AMP8 MK2 offers a double output. Indeed, it has a balanced output on 4.4mm jack and an unbalanced output on 3.5mm jack, allowing it to adapt to all listening devices.
