A flexible headphone amplifier capable of driving headphones with impedance comprised between 32 and 600 Ω.

Be ready for a nice surprise when listening to your headphones connected to this amplifier. Definitely the next step you need to rediscover your music in ways you didn’t think would be possible.

Built using 6DJ8 (ECC88) dual triodes, which provide a combination of sufficient current, enough gain and a simple but very smart application of a differential pair as a single stage, this amplifier is tolerant to impedance variations typical of headphones.

These tubes are compatible with 6DJ8 and can be used as direct replacements: ECC88, 6922, E88CC.
