Ray Samuels The Dark Star
This is the headphone Amp that can KICK the butt of the hard to drive headphones like the HE-6s. The custom, Plitron Toroidal, transformer is designed to output 80 volts at 6 amps of current to satisfy the 4 buffers that each is capable to deliver up to 9 amps of current. The Dark Star is truly a monster headphone amp. Nothing like it has ever been designed.
