state of the art, luxury audio, highend are all definitions for device that are optimised to reach the best possible Sound Quality with the corresponding excellent audio data.
The analog "king class" for the engineering is to build up a Phono preamp.
To reach the perfect Sound and the outstanding technical data we want, we have had to develop new discrete Gain stages and servo controlled Zero ohm headamps.
With an EIN from -144dBu the ML 7 Phono preamp is the lowest noise device on the market. You can hear it.
