Reference listening systems: the sound how it is, not how it should be.
Audio heaven in a pocket: Fully differential design audiophile headphone amplifier.

The reference headphone amplifier has been designed to faithfully reproduce the most subtle nuances contained in the musical message with the maximum detail and sobriety.

Two independent channels with independent power supplies for best channel separation and wider stereo image, fully differential (balanced) circuitry for improved linearity, dynamic response and definition, making the membrane much more prompt to signal solicitations.
Virtually immune to interference and noise, even in difficult environments.

The system comprises: the amplifier (main unit) and the special balanced cable. (Headphones must be recabled).

The components used are all selected with the strictest tolerance, and tested by ear.
