Aqua La Scala MKII Optologic D/A Converter

Aqua Hifi Technologies Hand Crafted in Italy
Since its introduction in 2010, the La Scala D/A converter has earned the distinction of “the standard reference in a class by itself”.

With its extraordinary sound quality and stylish appearance it has remained the DAC of discerning audio enthusiasts.

Improving the sonic performance of the La Scala was no small task. 

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, our aficionados, who bought 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.

Aqua Hifi La Scala Raves & Reviews

"...warm sonic embrace I can't imagine anyone in their right mind describing as "digital". It does have a sound though: It's wonderfully musical, inviting, enveloping, and entrancing."
