- LOWEST NOISE due to very small internal amplification. This makes the amplifier's inherent noise inaudible.
- HIGH OUTPUT VOLTAGE thanks to 50 volts of internal operating voltage. Therefore, it is ideally suited for high-impedance headphones.
- HIGH OUTPUT POWER thanks to powerful amplifiers that can deliver far more power than even the most demanding headphones could ever need. Therefore, it is ideally suited for low-impedance headphones and even magnetostats!
- HIGH DAMPING FACTOR due to the lowest output impedance. Therefore, it is ideally suited to drive even the most difficult headphones without interference, guaranteeing an uncompromising frequency response.
