AQUA ACOUSTIC La Voce S3

Review on 6moons

The new La Voce S2 combines product innovation and state-of-the-art technology, producing superior sound performance and the best styling.
Designed to provide absolute modularity and the ultimate in sound quality, La Voce S2 D/A converter is the culmination of years of aqua’s research in the areas of electronic engineering in relation to digital audio reproduction.

Further refined La Voce S2, a revolutionary design which employs modular R2R type converters in DFD configuration:

- cod. D104K - Burr Brown PCM1704-K (2 dac) - sign magnitude R2R ladder DAC 24bit / 192 kHz
- cod. D101 - Philips TDA1541A - R2R 16 bit / 96 kHz (R1, S1 grade selection on request)
- cod. D165 - Analog Devices AD1865 - R2R 18 bit / 192 kHz
