- The Segue Tube Mod is the addition of our popular Segue tube buffer stage mounted inside the chassis. This does not remove the c-dac's internal DAC chips. The signal is taken from the analog output of the unit and fed through the tube buffer stage.
- A rear mounted switch allows to choose between the standard solid state output or the Segue tube stage.
- The single 6922/ECC88 tube protrudes through the top of the chassis on the right side of the transport drawer
​- Volume control - If you prefer to run the modded c-DAC15.3 straight into your power amplifier, we can install a volume control on the top of the unit. Please note that if a volume control is desired, this eliminates the use of the solid state output and the unit is modified to run ONLY with the Segue Tube buffer stage.

The Segue tube stage utilizes a single 6922/6DJ8 dual triode tube and is run at voltages that allow you keep it on at all times. Input impedance is high at >800k ohms with a very low output impedance (a good thing) of only 90 ohms allowing you to mate the C-DAC15.3 to virtually any preamplifier or receiver.

-The power supply utilizes 2 separate high current toroidal transformers. A dedicated transformer for the +/- rails of the B+ supply and a separate, high current transformer for the new regulated DC supply boards feeding the tube filaments.
-Elna Silmic II capacitors are employed for power supply filter capacitors with last stage bypassed with high quality film cap.
-Ultra Fast diodes are used throughout.
-Clarity Cap output capacitors 
-Cryogenically treated Silver Plated/Copper/Teflon signal wire.
