↓ Details provided by HIFIMAN


This brilliantly designed, superbly powerful, and high-performing headphone amp makes the ideal companion to the brand's sublime headphones.

HiFIMAN excels at enhancing the headphone listening experience and the EF1000 is no exception. The brand pioneered the use of morphodynamic technology for their drivers, as opposed to the more conventional dynamic technology.

With headphone models as advanced as the HE-6 and other extremely hard-to-drive headphones, it must be driven by a powerful, high-caliber headphone amplifier. The EF1000 brilliantly answers this demand.

The driver's incredible thinness, less than a millionth of a meter, and extremely low mass mean it can produce tremendously low distortion levels yet offer a highly dynamic response. 

By combining this diaphragm and "Stealth Magnet" technology each working in harmony, the audio produced is of a remarkable tonal quality and clarity. 

The "Window Shade" on the SUSVARA has been painstakingly optimized to avoid arty-resonant frequencies. This leads to superior aural purity, tonally clean and unadulterated yet provides practical protection for the ultra-fine diaphragm and additional offering an appealing visual aesthetic.

The EF1000 is the SUSVARA's official amplifier, which utilizes a separate power supply design. Its SSRP circuit uses six 6922 vacuum tubes and six pairs of transmitters in parallel. The result is a perfect combination of the beautiful sound from the vacuum tubes and the powerful output of a solid-state amp.
