Aqua Acoustic Quality LA Scala MKII OPTOLOGIC DAC

 The new Optologic Conversion System

A never ending story: upgrading to the Optologic DAC

Again, La Scala D/A converter proves that an instant classic does not mean a product whose destiny is to become obsolescent, like most of the products in the high-end world.
After the first appearance in the flagship Formula DAC, the proprietary D/A conversion system developed by Aqua is now available for La Scala MkII dac.
So, current Owners, have the opportunity to upgrade their unit in order to reach to the revolutionary Optologic D/A conversion system.
The already extraordinary sound quality of this icon is now improved in every aspect: time coherence, microdynamics, timbre, and without losing that magic atmosphere for which La Scala is widely renowned.
La Scala MkII keeps the VALVE / MOSFET hybrid circuitry, with now a pair of specially selected ECC81 tubes - a High-Frequency triode - for its extremely low noise and superb transparency.


FEATURES:


• 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

av-corp is a trustful online shop selling genuine Wireworld connectors which are difficult to find elsewhere. Close to the German border, shipping was fast and tracking code just worked perfect for me. I could recommend the online store!
