Headonia 2A3 is a headphone amplifier only, specialy designed with the HIFIMan Susvara in mind. It has both - a single ended as well as balanced output, each with its own impedance selector. As a result, Headonia can easily drive all known headphone models on the market, and it can drive two pairs simultaneously. For an example, two Susvara headphones at the same time without any interference. The Headonia is a musical instrument that delivers the ultimate in listening and a true end game design for people looking for the best in reproducing the musical experience.

The Headonia should be easy on tubes and provide long life as the amplifier is never hot to the touch. The 2A3 direct heated triode is legendary in audiophile circles. The Headonia 2A3 outs a 3 watts of pure power, with two Electro Harmonix Gold 2A3 Tubes along with two JJ ECC81 tubes: 

  • On the front panel, from left to right, you have the 4-pin XLR balanced output, in the middle is the main volume control and right next to it, the 6.3 mm single ended headphone output. On the bottom of the unit you’ll find the air vents and the main power button, together with blue LED (lihght-on as soon as the amplifier turns on).
  • On the top of the unit you have the impedance selectors for both of the separate outputs, as well as the line-in selector switch. The four tubes are centered on the design and they’re protected with a little grill, separating them from the controls.
  • On the back of the unit from left to right you can find the four RCA inputs, the tube balancing control pots and the power connector.


To enable the users to dial the appropriate impedance settings, Headonia 2A3 has two impedance selectors for each of the headphone outputs. This allows the users to switch and choose the impedance for the headphone being used and have 32/80/150/300/600 Ohm settings. Which in turn makes the Headonia 2A3 ideal for driving various types of headphones.


The amplifier has a linear natural sound, layered from the top to the bottom. The midrange has sensational performance with vocals. The clarity and transparency are all delivered flawlessly. Treble extension seems to always soar and felt endless. The sound coming from the treble is always clean and never made trumpets or violins sound harsh, the tonality of instruments is simply exceptional. Bass had both slam and texture and the extension is excellent, detailed and when called for, it delivers a thunder in producing the sound.
