APL Hifi DSD-AR

The DSD-AR is the new most affordable junior member of our digital products family. Just like its bigger brothers, the DSD-AR is specifically made for those enthusiastic audiophiles who search for a 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.

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

The DSD-AR offers a unique sound quality which is in line with our “house sound”. We are certain that many audiophiles will fall in love with it, especially given the price-performance ratio.

Digital Processing
