A headphone Amplifier to Achieve peak headphone performance
In general, a headphone output from conventional hi-fi components does not allow even high-quality headphones to perform at their peak potential. The same way one chooses an amplifier to match with your favorite speakers, it is very impotant to chosse an appropriate headphone amplifier that matches your favorite headphones. A headphone amplifier is a "must-have" listening device for audiophiles.
Active DC Servo Technology for decreased distortion, and discrete Class-A Amplifier
In order to develop a first-class low distotion Class-A headphone amplifier, TEAC held a series of sound evalutions during the development. These tests led to the careful choosing of parts and descrete circuit design. In addition, like most full-size hi-fi components, in order to eliminate Offset Electrical Potential, Active DC Servo Technology is utilized.
Dual Monaural Design that eliminates interference between Left and Right channels
In regards to the circuit design, each channel is completely designed on an individual basis to avoid signal interface to/from another. This contribution eliminates cross-talk, crucial headphone listening.
MUSES8920 Op-Amps - for high-end quality
MUSES8920 Op-Amp chip-sets are designed for high-end audio. Employed individually on the Left and Right channels, they help achieve superior sound. This Op-amp performs superb IV-conversion and is already very well regarded and used in a wide-range of hi-fi components.
