    Default AQUA HIFI La Scala DAC

    Aqua hifi La Scala DAC (hand made in italy) on demo now:







    FEATURES:

    • High performance proprietary DFD (Direct From Decoder) digital decoding without digital filter for purest digital signal quality

    • Custom designed discrete circuit with high-speed photocouplers for Galvanic and magnetic isolation between Digital stage and Analog DAC ground

    • Jitter free digital interface AQlink (I2S protocol), uncompromising digital connection to La Diva cd transport

    • Precision sign magnitude R2R ladder DAC with 4 Burr-Brown PCM -1704K arrayed in a true differential dual mono configuration

    • Transformer current / voltage conversion (I / V)

    • Zero S/PDIF Jitter design, digital receiver stage PLL (phase locked loop) technology

    • High-performance AQ Discrete Regulator (MOSFET, J-FET, BJT) for analog and digital DAC’s power supply

    • Valve-Mosfet direct coupling analog stage in pure class-A without negative feedback

    • MOSFET Virtual battery circuit for analog anode supply

    • Soft-start power up for extended tube life

    • etherCON RJ45 (AQlink) input connection, employs CAT6 cable can connect both RJ45 and professional etherCON RJ45

    • 2 separate low noise power transformers, one for the analog and one for the digital section

    • MODULAR DESIGN with upgradeable multi board system

    • Regulated DC filament supplies with soft start for tubes

    • 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 up to 24 bit and 192 KHz, operates with computers running OSX 10.7 and above, WINDOWS XP, 7 and 8 ASIO - WASAPI bit perfect high-speed

    • Digital phase selector on front panel

    • High-quality parts selected for sound quality:
    - 105° long life capacitors
    - low noise Metal Foil ultra-precision resistors
    - double metallized film pulse capacitor
    - ultra-fast diodes
    - halogen free cables

    • Aluminum anti-resonant cabinet with Nextel

    • Designed and handmade in Italy

    • Input:
    - etherCON RJ45 AQlink (I2S serial bus) - 24 bit / 384 KHz
    - AES/EBU balanced 110 ohm - 24 bit / 192 KHz
    - BNC coax (S/PDIF) 75 ohm - 24 bit / 192 KHz
    - RCA coax (S/PDIF) 75 ohm - 24 bit / 192 KH
    - USB port - 24 bit / 192 KHz
    - AT&T (ST Fiber) - 24 bit / 192 KHz (optional)

    • Analog output:
    - RCA single-ended
    - XLR balanced symmetrical
