The Intrepid Digital to Analog Converter


The Intrepid DAC is finished.

It has the same digital inputs as the Heritage DAC and also the same configuration with 3 chassis: DA section, Analog Power Supply and Digital Power Supply.

In contrast to the Heritage DAC which has a single ended analog stage, the Intrepid DAC has a fully balanced discrete R2R DAC which feeds a balanced output stage with 2 directly heated triodes per channel. 

These are coupled to the output with a silver wound transformer without any capacitors in the signal path. With a total of 6 signal relevant transformers and inductors wound in silver.

All three chassis are milled from solid blocks of aluminum.

Like the Heritage DAC this one can be ordered with different kinds of output tubes.

As standard it is equipped with the 'ONE' a new tube development by Deutsche Elektronenröhren Manufaktur GmbH exclusively for my electronics.

The ONE comes with 5 years warranty.

The ONE uses a cylindrical arrangement of the electrodes for perfect symmetry in all directions from filament to plate. This results in very linear plate curves.

This DAC will be on demo at the upcoming Munich High End Hall2, F06

Best regards
