Aqua Acoustic Quality La Voce S3 Discrete DAC review Page 3


  • High performance proprietary FPGA-based digital decoding without digital filter
  • Discrete R2R ladder DACs with low noise precision resistors
  • Galvanic isolated S/PDIF - AES/EBU Digital input
  • Jitter free digital interface AQlink (I2S protocol), uncompromising digital connection to La Diva cd transport
  • Zero S/PDIF Jitter design, digital receiver stage PLL (phase locked loop) technology
  • Discrete Regulator (MOSFET, J-FET, BJT) for analog and digital DAC’s power supply
  • RJ45 (AQlink) input connection, employs CAT6 cable
  • Two separate low noise power transformers, one for the analog and one for the digital section
  • MODULAR DESIGN with upgradeable multi board system
  • Fully discrete analog stage, not even a single Op-Amp is used
  • Proprietary USB Firmware/driver: Apple MAC OS - Linux OS : USB asynchronous native support, no need to install drivers software
  • Fully upgradeable asynchronous USB module with resolution 44.1kHz to 384kHz PCM up to 24 bits, DSD64, DSD128, operates with computers running OSX 10.7 and above, WINDOWS 10 , 8 , 7 and XP ASIO - WASAPI bit perfect high-speed
  • AQ-i modular input: D111 XLR/D112 AT&T ST Fiber/D113 RCA/D114 TOSLINK with High Resolution platform
  • Digital phase selector on front panel
  • High-quality parts selected for sound quality: 105° long life capacitors/low noise Metal Foil ultra-precision resistors/metallized film pulse capacitors/ultra-fast diodes
  • Aluminum anti-resonant cabinet with Nextel
  • Designed and handmade in Italy
