The DSD-SR MK2 is specifically made for those enthusiastic audiophiles who search for the most natural and analogue-like digital audio reproduction offered by an all-solid-state DAC design.

It is an all-hand-made boutique, designed and built with the best possible audio quality in mind for its price-range.

Just like the DSD-MR MK2 reference converter, the DSD-SR MK2 is inspired by vinyl sound quality, and it provides a comparable rich and spacious sonic character.

From the quadruple DSD processing rate, to the transformer-coupled Class A output stage, the DSD-SR MK2 offers a high level of technology advancement and refinement.

The DSD-SR MK2 is based on a modular design, allowing a cost-effective future upgradability of any internal stage.
