Aqua La Scala MKIII Optologic DAC
FEATURES
More than a simple upgrade for our La Scala DAC
• High performance proprietary FPGA-based digital decoding without digital filter
• Galvanic and magnetic isolations between the FPGA and R2R ladder converter
• Discrete R2R ladder DACs with low noise precision resistors
• 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
• 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. High output current capability and the exceptional piloting performances of PIBU (Pilot Buffer) new module.
• 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 double C-core 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
