Hifiman's latest reference amplifier

This headphone amp, brilliantly designed and powerful, is the perfect match for Hifiman's exceptional headphones. Hifiman excels in improving the headphone listening experience, and the EF1000 is no different. The brand was a pioneer in utilizing orthodynamic technology for their drivers, rather than traditional dynamic technology. With headphone models as advanced as the SUSVARA, which requires a powerful, high-quality headphone amplifier, the EF1000 meets this need flawlessly.

The ultimate complement

The EF1000 is the official amplifier for the SUSVARA, featuring a separate power supply design. Its SRPP circuit incorporates six 6922 vacuum tubes and six pairs of transistors in parallel, resulting in a blend of the vacuum tubes' beautiful sound and the solid output of a state-of-the-art amplifier.

Hybrid design

The headphone output is 20w pure Class A, while the amplifier output is 50w pure Class A and 110w Class A/B. The SRPP circuit utilizes six 6922 vacuum tubes and six pairs of transistors in parallel, along with a separate power supply design. The EF1000's volume control employs relay-based attenuator technology from the SHANGRI-LA, delivering a smooth response and minimal distortion due to its dedicated pathways.

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
