FEATURES: The Aqua La Scala MKII Optologic DAC is a high-end digital-to-analog converter designed and manufactured by the Italian company AQUA. • 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 • 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 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 • 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 • Aluminium anti-resonant cabinet with Nextel • Designed and handmade in Italy • Input: – RJ45 AQlink (I2S serial bus) – PCM 24 bit / 384kHz – DSD64, DSD128 via DoP – BNC coax (S/PDIF) 75 ohm – PCM 24 bit / 192kHz – DSD64 via DoP – RCA coax (S/PDIF) 75 ohm – PCM 24 bit / 192kHz – DSD64 via DoP – AES/EBU balanced 110 ohm – PCM 24 bit / 192kHz – DSD64 via DoP – USB port – PCM 24 bit / 384kHz – DSD64, DSD128 via DoP – AT&T (ST Fiber) – PCM 24 bit / 192kHz – DSD64 via DoP (optional) • Analog output: – RCA single-ended – XLR balanced with transformer . SOUND QUALITY: The La Scala MKII is praised for its exceptional sound quality, with reviewers highlighting its tonality, timbre reproduction, soundstage depth/width, fine detail retrieval, and ability to handle complex musical passages. Its tube output stage is said to provide a seductive, liquid midrange without compromising speed or dynamics. The lack of a digital filter and the R2R architecture contribute to its highly resolving and transparent sound. . LISTEN TO BELIEVE – We invite everyone to visit our shop!
