APL Hi-Fi DSD-S : 

ON DEMO AT THE SHOP - The DSD-S is APL Hi-Fi's mid-line Digital to Analog converter, specifically made for those enthusiastic audiophiles who search for a no compromise 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-M reference converter, the DSD-S is inspired by vinyl sound quality, and it provides a comparable rich and spacious sonic character.
The DSD-S represents the culmination of our 25 years digital and analog design experience, as well as component selection knowledge.
From the double DSD processing rate, to the MOSFET Class A output stage, the DSD-S offers a high level of technology advancement and refinement.

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