The Roma 69DC has USB "B" type, DSD 5,6MHz, and optical input. 32Bit of resolution gives you a fantastic sound stage and beautiful sound reproduction.

Using an 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. Particular attention has been dedicated to the headphone output. Using a high-fidelity driver, we obtained an incredibly natural sound performance, the sound stage is simply perfect!

To back this up the design has an over size shielded power transformer to reduce the interference. An array high grade metalized polypropylene capacitors controlling the audio signal circuits. The all-important component of this unit are run by a multi-stage fully regulated power supply.
