The product name appears to refer to the K&K Audio / Raleigh Audio RAKK Tube DAC in a Standard/Extreme configuration, rather than a phono preamplifier. It is a modular vacuum-tube-output digital-to-analog converter built around K&K Audio’s RAKK DAC platform. Available evidence identifies a unit configured with the MkIII DAC board, I²S Three-Input Adapter, 24-bit/192 kHz USB Adapter, Standard Power Supply, Standard Voltage Regulator, and Standard Active Output Stage. The supplied tube complement is reported as two Russian 6H6Pi tubes. Configuration-dependent options existed, so unavailable measurements and mechanical details should not be inferred from similarly named RAKK products.
