Using a ECC88/6DJ8 on the output stage as differential amplifier for a perfect matching with the Dac’s output (Asahi Kasei AK4495S ), obtaining a very low output impedance and extremely large bandwidth.
To back this up the design has an over size shielded power transformer for reduce the interference. An array high grade metalized polipropilene capacitors controlling the audio signal circuits. The all important components of this unit are run by a multi stage fully regulated power supply. Paticular attention has been dedicated to the headphone output.
