D/A Converter Rockna Audio Wavedream DAC Reference Standard Silver
Description
The Rockna Wavedream Reference is a flagship digital-to-analog converter and network renderer, utilizing a custom software-defined architecture powered by an AMD/ZYNQ SoC and four discrete FPGAs. It avoids off-the-shelf DAC chips, opting for proprietary discrete hybrid ladder (R2R) modules in a symmetrical, fully balanced layout. Featuring an ASRC-free digital PLL clock topology, custom Parks-McClellan 16x upsampling filters, and a hybrid ultra-low-noise power supply with over 90,000 µF of capacitance, it delivers extreme signal integrity. Its discrete Class-A JFET/bipolar analog output stage yields a highly transparent, natural, and musically coherent soundstage.

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.
