Testimonials (on all versions of the La Scala)

"Music positively bursts into life.... In other words, the most satisfying DAC heard by yours truly to date just got significantly better. In its Optologic incarnation, the La Scala MKII cements further its position at the very top of the DAR-KO DAC Index and DAR-KO Award assignation becomes as easy as it has ever been. In a word, primo!" - John Darkpo, DigitalReveiw.net (read the review) "...That it manages an ideal balance between speed and substance tells you why it had my vote. A most analogue digital deck, albeit sans volume control!" - Srajan Ebaen, Sixmoons.com (read the review) "No DAC impressed me more in 2014 - or any other year for that matter - than the Aqua La Scala MKII... the best-sounding D/A converter we’ve heard to date. The La Scala’s almost sentient way with drama and textural reveal puts it at the very top of the Darko DAC Index" - John H. Darko, Digital Audio Review (read the review) "Excellent musical presentation of the two devices. The converter : I hate to give back." - Jürgen Saile, HiFi Statement ""the best ever for my system." - René Van Es, The Ear

Overview

Aqua 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. Now, 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, Aqua aficionados, who bought the La Scala MkII dac before, have now 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 selected Telefunken ECC81 tubes - a High-Frequency triode - for its low noise main feature.
