High Resolution Tube DAC
The Roma 69DC has USB "B" type, DSD 5,6MHz and optical input. 32Bit of resolution give you a fantastic sound stage and beautiful sound reproduction.
Using a ECC88/6DJ8 on the output stage in 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. Paticular attention has been dedicated to the headphone output. Using a high-fidelity driver, we obtained a incredible natural sound performance, the sound stage is simply perfect!
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 component of this unit are run by a multi stage fully regulated power supply.
