Product Description

TEAC HA-501 headphone amplifier is an accomplished full-analog, class A, dual mono design with vintage styling cues and adjustable damping factors to match it perfectly to the headphones you're listening with.


With full metal casing and a beautifully finished fascia it's a pleasure to use, and its A4-sized footprint makes it a perfect choice for your desktop. Everything on the HA-501 is designed to maximise the potential from your headphones and to drive them properly in the way the output on most hi-fi systems and computers can't.

If you haven't tried your headphones through a proper headphone amplifier or a lesser capable alternative, you'll be surprised by the silky smooth, dynamic sound possible from this TEAC.


In contrast to its similarly priced rivals, the HA-501 includes both XLR and RCA audio inputs, with 1 and 2 sets of each respectively as well as RCA line out so you can use it in between your source and hi-fi system if you wish, in addition to a 3.5mm input on the front for connecting your portable music player. For something refreshingly different, the HA-501 is an excellent partner for headphones listening.


If you're looking for headphones, we recommend partnering with Grado RS1i, Grado PS500, Grado GS1000i, Sennheiser HD800, or Audio Technica ATH-W1000X models.

Please feel free to call to speak to one of our product specialists for further advice or book an appointment for a demo and listen to a wide range of headphones in our showroom.
