EARMAX amps in general are OTL design (OutputTransformerLess). The actual output power and quality is depending on the load connected. Low impedance (low Z) headphones draw a lot of current and this requires a higher current power supply.
The lower the headphones impedance is, the higher the power of the OTL amplifier is needed.
The Brocksieper EARMAX Silver Edition headphone amp is optimised for this and comes with a very strong power supply. The SE is the identical design like the Brocksieper Anniversary model (just silver instead of gold hardware and no flightcase) known and prised for its outstanding performance among HiFi enthusiasts.
