Our EarMax headphone amplifier line features OTL class A triode technology for maximum listening performance for dynamic headphones.
We apply a very minimalistic tube design with Noval double triodes in the input and power section (ECC81 and ECC88).
Our EarMax amplifiers come with an external power supply.
All tubes are hand selected and individually tested. Each unit undergoes a strict quality check and measurement, a 24 hours stress test and fine-tuning, prior to being shipped.
The first EarMax generation started 15 years ago. Due to the overwhelmingly positive customer feedback we have gradually improved the product over time whilst maintaining the integrity of the original design.
2004 we launched our EarMax Anniversary line (limited edition to celebrate the 10th anniversary of EarMax) and 2005 we revealed the “silver edition” variant with increased output power.
Variants
EarMax Pro – for all dynamic headphones with impedance beyond 35 Ohm. For maximum performance we recommend headphones with 200-2000 Ohm impedance.
EarMax – Silver Edition – stronger power supply and output stage for low impedance dynamic headphones (more than 20 Ohm).
