Model TWO amplifier

Just like our model ONE amplifier, the model TWO is an SE OTL amplifier. The main difference is in the principle in which the output signal is being generated. Our model TWO has a tube-based CCS for best sonic and linearity. Other differences include DC (direct current) coupling to the first stage and higher current driving capability.

The CAT module (for use with model ONE and TWO amplifiers only)

This step-down CAT (cathode auto-transformer) module is the result of years of research and development that enables our headphone amplifiers to be used as low power output speaker amplifiers. This module significantly expands the flexibility of our headphone amplifiers and can deliver 2 W of power at 8 Ohm load. Providing the use of high sensitivity speakers, this will be enough for a small room or an office.
