D/A Converter Rockna Audio Wavelight DAC Silver
Description
The Rockna Wavelight DAC is a high-performance software-defined digital-to-analog converter engineered to deliver discrete R2R ladder precision paired with organic, analog musicality. Built upon a Xilinx 7-series FPGA running custom-written VHDL code, it synthesizes all core digital processing and ladder-control functions within programmable silicon. This architecture allows the internal hardware topology to evolve via firmware updates, providing obsolescence protection and continuous sound enhancements. Serving as a versatile front-end, the Wavelight DAC combines custom digital filter designs, a discrete resistor network topology, and Rockna's high-performance digital standards in a timeless, solid-milled chassis.

Rockna Audio
The Romanian company Rockna Audio was founded in 1999 with the aim of creating products for sophisticated, enjoyable and inspiring music reproduction. Its founder and chief designer, Nicolae Jitariu – who has also applied his experience in digital audio to developments for brands such as Goldmund, PS Audio and MSB – builds his products from scratch using his own designs. All products are developed exclusively in-house and in the company’s own laboratories, without resorting to standard, off-the-shelf designs.
At the heart of Rockna’s converters lies the company’s own architecture of a discrete R2R converter controlled by an FPGA circuit, which, instead of conventional D/A chips, delivers a natural, full and detailed sound with support for both PCM and DSD up to DSD512. The portfolio is complemented by network players, preamplifiers with D/A converters and music servers. Rockna is the choice for audiophiles who expect analogue naturalness from a digital source and modern streaming without compromise.
