The world’s highest level of headphone audio playback.
With the great variety of headphone choices, it is only possible to achieve the best performance with a single headset in mind. You can not use the universal headphone amp concept with the Select level of performance. That is why we have built a dedicated Stax* headphone amp to be paired the the Select DAC.
The Electrostatic Headphone Amplifier has been designed to take advantage of the powerful DAC outputs. This allows it to achieve a level of headphone playback never heard.
If you are sharing the headphones with a two channel system, use an internal bypass in the amp. Simply turn off the unit for the signal to be sent to your other system.
A discrete passive equalization module slot is included with the amp. This allows for slight analog adjustments of the amplifier to accommodate new headphone designs in the future. This can also be used to tune the system for your preferences.
