AQUA La Voce S3
DAC converter
The new S3 Discrete | La Voce to the next level.
Designed to provide absolute modularity, the Voce S3 is a pure R2R ladder: FPGA-based DAC with no digital filter. It has a sign-magnitude ladder converter.
The absence of digital filtering means that there is no processing of the input signal. The original digital samples are translated into the reproduced sound, preserving the transient shape and avoiding any sound.
In this way, we also avoid the problem of "intersample overs" that is vital for faithful reproduction, considering the current practices of recording studios.
With our R2R conversion technology, the sound is natural, fast, dynamic and without the feeling of compression that characterizes other converters.
