The S3

The new La Voce S3 board structure swaps out the PCM1704 chips for in-house designed Discrete R-2R boards, similar to those found in the flagship Formula xHD and La Scala Optologic. A SPARTAN-6 FPGA chip will handle data reception with changes also made to the USB board – now DSD128- and 384kHz PCM-capable – as well as the I2S board and mainboard.

"...The La Voce S2 from Italy pursues the Audio Note, AMR, Metrum, Zanden & Co. type sound for a lot less than most..." - Srajan Ebaen, Sixmoons



Aqua Acoustic Quality, known most commonly as Aqua Hifi, makes Non oversampling DACs, and a CD transport. Their passion and focus is on musicality. Period. Their products touch the soul of the musical performance in a way that is very rare in the high end audio industry, and virtually non existant at this price point. 

Experience the Soul of Music

We are living in an age where most recordings are less than stellar (at least the ones we like to listen to when not demoing gear) and most audio components are sonic scalpels. Serving up gobs of detail in a lifeless, sterile manner. Where is the soul of music? What do I need to do to hear THAT? Well, you could attend more live musical events. But when that isn't possible we suggest you listen to music through the La Voce DAC.

"...listening to the La Voce S2 brought on a little rear-view reflection: not since owning a Marantz CD63 MKII back in the mid-90s do I recall such continuous easeful listening with ALL source material (and not just the nicer sounding stuff). A kindness-to-all delivery is the most noticeable way in which this Aqua DAC sets itself apart from the competition..."

"...the La Voce S2 is for those who want to eat cake without being explicitly reminded of flour, butter and sugar...."John Darko, Digital Audio Review
