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 important to choose 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 distortion Class-A headphone amplifier, TEAC held a series of sound evaluations during the development. These tests led to the careful choosing of parts and discrete circuit design. In addition, like most full-size hi-fi components, in order to eliminate Offset Electrical Potential, Active DC Servo Technology is utilized.
A Large Toroidal-core Power Transformer
An over-sized Toroidal-core power transformer is also employed to supply stable current to the every part of the circuit.
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
A couple of MUSES8920 Op-Amp chip-sets are designed for high-end audio. Employed individually on the Left and Right channels, they help achieve superior sound.
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.
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 forwards and backwards as sound. The value of the Damping Factor varies model by model, as diaphragms are made by different materials, in different shapes or different construction designs. Since headphones’ diaphragms are activated by a very small current compared to conventional speakers, the damping factor increases, the sound is lean and crisp, and has a close relationship with headphones’ impedance. Therefore, selecting the right Damping Factor is crucial in order for your headphones to perform at their peak potential. The HA-501 provides 5 selectable Damping Factors, so users have the best suited signal for multiple headphones.
Robust Aluminum Body with a Classy Appearance
Re-defining high class hi-fi components, 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. In order to ensure its rugged design, each panel is connected with a beam that runs through the center of the unit. Normally, this type of construction is only for full-size components, particularly CD players that generate inherent motor vibrations. This construction ensures the HA-501 is an authentic hi-fi component that will last you for many years. Choose between a handsome black version and a brilliant silver version to match with any interior or design.
Well-designed User Interface
Another remarkable feature of the HA-501 is the user-friendly. 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 sound 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.
Switchable Output Mode for flexibility
Line output level from the rear panel can be switched amongst “Fixed Level”, “Variable Level (coupled with volume)” and “Off”.

Up to 90 Day Returns!

Returns are easy and flexible. We will accept returned goods up to 90 days from purchase with the following restrictions as summarised below. For more details please read our Terms & Conditions of Sale, a link is shown at the bottom of the home page.

Changing your Mind
It's OK to change your mind but please be aware that all goods must be returned in as new, unused and re-saleable condition. This means that all packaging must be intact, all accessories are complete in their original wrappers and any free items are also returned with the goods. Essentially the product must be returned in the same condition as you would expect to receive a new unit in. In all cases the cost of returning the goods will be the customer's responsibility. All faulty items must be returned complete and will be repaired under the manufacturer's warranty.


How we Handle Returns
Depending on how long you have had the goods there are different options availble to you. In the case of faulty items, if the item fails due to a manufacturing fault between 1 and 28 days from delivery we will exchange it for a brand new one of the same model. Any items which are found faulty after 28 days from delivery will be repaired under the manufacturers warranty. For returns where you have changed your mind, please find our policy below:


This is were you return your item and we will exchange it for another item of equal or higher value. If the item you wish to change to is of higher value you only pay the difference. If the item is of a lower value we will issue you with a credit note for the difference which you can spend with us at a later date.

Credit Note
This is where you return your item and we issue you with a credit note which you can use against another purchase with us.

This is where you return your item and we issue a refund back to the same method you paid with. e.g. the same credit card. This is not available after 14 days, only exchange or credit note is available after 14 days.

25% Restocking Fee
If your item is returned to us between 29 and 90 days from delivery we will charge a restocking fee of 25% of the price you paid for the item initially. This will be deducted from the value of the exchange or credit note which is issued to you. This is because  technology in the AV marketplace moves fast, and as a result the value of items decrease very quickly.

Please note we do not accept returns after 90 days, except for repairs under warranty.

To complete your order please call us on 0800 634 4484
