Thomas Mayer Heritage DAC

The Thomas Mayer Heritage DAC consists of three chassis. One is for the digital power supply, one for the analog power supply, and one for the actual signal section.

The signal section uses a discrete R2R DAC that feeds into the grid of the output tube, which in turn is coupled via a transformer to achieve a low output impedance. This is the purest signal path you can get. All analog amplification is provided by directly heated triodes.
