Every set of Cayin HA-6A comes with two sets of power tubes, the Genalex Gold Lion KT88 and the Electro Harmonix EL34. You can configure your amp for different vacuum tubes elevating the music listening experience on your headphones. Change output as well as the sound signature instantly with the dedicated dual operation mode: Triode and Ultralinear. You can optimize the entire system depending on the music application. Under the Triode mode, you get tendering, rich harmonics, smooth and lush holography making it perfect for vocals and string music. If your music requires punch and dynamics, the ultra-linear mode is ideal for you.

To match the impedance levels of headphones, the HA-6A comes with indigenously developed output transformers. These transformers come with three sets of impedance matched outputs: Highs, Mids and Lows ranging from 8Ω to 600Ω.
