APL Hifi DSD-MR

The DSD-MR MK2 is our top-line Digital to Analog converter, specifically made for the most enthusiastic audiophiles who prefer analogue-like sound, comparable to state-of-the-art vinyl and respectable reel-to-reel machines.

It is an all-hand-made boutique, designed and built with the best possible audio quality in mind, cost-no-object.

Inspired by pure analog sound quality, the DSD-MR MK2 pleases with a very natural sonic character that is truly unique.

From the DSD512 processing rate to the differential transformer-coupled Class-A tube output stage, the DSD-MR proves technology and refinement of the highest level.

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