12V Output for Power Supply:

This quick-turnaround mod will take your existing supply and add an additional output to power DAC DAC.  Recommended for Stereo Maraschino owners esp. Includes special 12VDC cable for DAC DAC.   DAC DAC requires a clean, stable 12V power source.

3x Capacitance:

This one isn't for the faint of heart. Upping the capacitance right on the amplifier circuit gives Maraschino the kind of drive and impact that is usually reserved for military weapons. 3x the capacitance can be only squeezed into Desktop Maraschino. Know of any other amplifiers that have a Triple-Size option?
