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.
