Audiophile headphone amp with switchable damping factor.

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 important to choose a headphone amplifier that matches your favorite headphones. A headphone amplifier is a "must-have" listening device for audiophiles.

In order to develop a first-class low distortion Class-A headphone amplifier, TEAC held a series of sound evaluations during its development. These tests led to the careful choosing of parts and discrete circuit design. Each channel is completely designed on an individual basis to avoid signal interface to/from another. This eliminates crosstalk, crucial for 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. Additionally, alarge Toroidal-core power transformer is employed to supply stable current to the every part of the circuit.

Damping Factor Selector to optimize headphones' characteristic
Each pair of headphones has its Damping Factor, a resisting force against non-intentional movement of the diaphragm moving air forward and backward as sound. The value of the Damping Factor varies model by model, as diaphragms are made of different materials, in different shapes or different construction designs. The HA-501 provides 5 selectable Damping Factors, so users have the best-suited signal for multiple headphones.

Total 2,800mA of output power drives your high impedance headphones
The HA-501 achieves a remarkable 1,400mW output power per channel at 32 ohms impedance. The device delivers not only enough power to drive standard headphones with an impedance range from 80 to 250 ohms, but also high-class 600 ohms hi-fi headphones.

Robust Aluminum Body with a Classy Appearance
The HA-501 has a small footprint, classy appearance and is constructed with aluminum panels to create an authentic but modern looking hi-fi component. A robust metal construction helps eliminate vibrations that may affect the sound quality. The bottom and sidewalls are formed with a steel chassis, aluminum for the front panel and the rear panel out of steel. Each panel is connected with a beam that runs through the center of the unit. This ensures the HA-501 is an authentic hi-fi component that will last you for many years.


Well-designed User Interface
Another remarkable feature of the HA-501 is the user-friendly design. The firm-torqued volume control allows users to adjust the volume level with ease and precision while the toggle-type power switch assures ON/OFF operation at a glance. Auto-muting function protects your ears from unexpected loud sounds when switching between headphones with different levels of impedance.

Professional grade Input/Output connectors
On the rear panel, a pair of NEUTRIK brand XLR input connectors allow users to connect high-end components or professional audio equipment, while wider-pitch RCA pin jacks allow user to connect large-shaft RCA pin cables from other markets. A detachable type 3-polar power inlet socket is also available. On the front, a 3.5mm stereo mini-jack allows users to connect a portable music player such as an iPod, conveniently.


If you have the headphones of your dreams, you need to take one last step for sound perfection.
