Details

APL Hi-Fi DSD-MR : 

The DSD-Master Reference is our top-line Digital to Analog converter, specifically made for the most enthusiastic audiophiles who prefer true analog sound, comparable to state of the art vinyl.
It is an all-hand-made boutique, designed and built with the best possible audio quality in mind, cost-no-object.
Inspired by reference vinyl sound quality, the DSD-MR pleases with a very natural sonic character that is truly unique.
It represents the culmination of our 25 years digital and analog design experience, as well as component selection knowledge.
From the quadruple DSD processing rate, to the differential Class-A tube output stage, the DSD-MR proves technology and refinement of the highest level.

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

Features
