Aqua hifi (hand made in Italy) La Diva cd transport on demo now




Custom designed discrete circuit with high-speed photocouplers for Galvanic and magnetic isolation between CD drive unit and digital output

Ultra massive chassis construction and newly developed high-rigidity sub chassis with Nextel for CD drive unit cancels internal and external acoustic and mechanical vibrations, enabling exceptionally accurate "Red Book" RF signal

DC disc drive motor allows to read the data accurately and minimize Jitter

Moplen clamp to avoid flywheel masses and vibrations

Sophisticated signal processing technology assures excellent CD Red Book signal

High-performance multi-stage voltage regulator (high-current stage for accurate servo DISC drive rotation, tracking and focus)

Jitter free digital interface AQlink (I2S protocol), uncompromising digital connection to La Scala DAC, La Voce DAC

etherCON RJ45 (AQlink) outputconnection to DAC, employs CAT6 cable can connect both RJ45 and professional etherCON RJ45

Separate custom-built toroidal transformers for digital and servo motors/actuators

MODULAR DESIGN with upgradeable multi board system

Precision Philips CD-Pro2 transport customized

High-quality parts selected for sound quality:
