USB-DAC Headphone Amplifier

Sublime and Organic Tone from the Vacuum Tube

Combines the beautiful, warm sound signature of vacuum tubes with the advantages of low distortion and high S/N rate from the solid-state amplifier.

Hybrid Design: Vacuum Tube + Solid State Performance

The hybrid design employs two 6J1 tubes for its input stage and incorporates the OPA2604 along with discrete components for its output.

Step Potentiometer for Improved Volume Attenuation

The Step Potentiometer is designed for precise control and accurate channel balance (with less than 0.0001 in errors). This results in excellent channel balance and soundstage.

Hi-Fi Sound Quality

The EF2C is meticulously designed for the most discriminating music listeners who demand the best performance and value.

Style and Power

A compact desktop design with an integrated USB-DAC inherits the power and performance from the EF2A.

The EF2C is the perfect match for most PC-driven audiophile headphones.
