The Rockna Wavedream DAC is a flagship software-defined digital-to-analog converter built on an FPGA-based digital engine, allowing the device hardware and algorithms to evolve via firmware updates. At its core is the Femtovox clock system, synthesizing the master clock directly at the DAC input to achieve an ultra-low jitter of 300 femtoseconds and 1 ppb accuracy. Featuring 58 DSP blocks executing custom Parks-McClellan 16x upsampling filters, discrete sign-magnitude R2R ladder DAC modules (RD-0 for Signature, RD-1 for Edition), a fully discrete Class-A JFET/bipolar analog output stage, and a 20-stage linear power supply driven by three custom transformers, the Wavedream delivers unmatched transparency, low noise, and organic sound reproduction.

With a commitment to developing and manufacturing audio products that create sophisticated, enjoyable and inspiring music reproduction, Rockna Audio was founded in 1999. The Romanian company is constantly evolving and motivated by its passion for technology, which is reflected in original products made entirely in-house, in their own laboratories, with internal structures built from scratch, so to speak, avoiding standard solutions as much as possible.
