D/A Converter Rockna Audio Wavedream DAC Reference Signature Silver
Description
The Rockna Wavedream Reference Signature elevates the core Reference digital platform to the absolute pinnacle of performance, featuring enhanced R2R ladder DAC modules (RD-0 MK2) and an upgraded, fine-tuned discrete Class-A analog stage. Driven by an AMD/ZYNQ SoC with four dedicated FPGAs and an ASRC-free Digital-PLL Femtovox clock system, the Signature version achieves a staggering 139 dB dynamic range and a higher output capability (up to 7V RMS via XLR). It provides unmatched control over micro-details, ultra-low distortion (-102 dB THD), a dead-quiet noise floor, and an impeccably holographic, organic presentation.

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.
