L'avis de Noir & Blanc
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 first step was to enhance the overall precision of the digital circuit. La Scala MkII inherits the innovative proprietary DFD decoding without any digital filter, assuring a pure and precise digital signal. In addition aqua - acoustic quality has developed a single-stage signal amplifier: VALVE / MOSFET direct-coupled and LED bias. It uses ECC81 tube - a High-Frequency triode - for its low noise main feature. This is directly connected to High-Voltage MOSFET to enable :
- simplicity
- wide bandwidth
- fast response
- no overshoot, no ringing, no roll-off
- lower output impedance compared to conventional circuits
- no feedback
- low distortion
La Scala MkII uses long-life valves with an average life of approximately 10,000 hours.
