SUSVARA+EF1000 Planar Perfection
SUSVARA and EF1000, both crafted by HIFIMAN with each other in mind, are perfect complements or what we call Planar Perfection.
Harmonious Sound Sweetly Voiced
Acoustically Invisible Stealth Magnets
The advanced magnet design used for the first time on the SUSVARA, aims to be acoustically transparent, dramatically reducing wave diffraction turbulence which degrades the integrity of the sound waves. The result is reduced distortion, yielding a purer, more harmonious sound that is audibly so.
Unlike the sound waves created by a conventional magnet, the special shape of stealth magnet of SUSVARA enables the waves to pass through the magnet without generating interference.
The driver's incredible thinness, less than a millionth of a meter and extremely low mass means 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 any 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.
Form Follows Function
Special ergonomic design for superb comfort and extended listening
EF1000: A Planar Powerhouse
HIFIMAN's No-Compromise Amplifier When Only the Best Will Do
Perfect combination of the beautiful sound from the vacuum tubes with the powerful output of a solid-state amplifier.
The EF1000 can drive even the least sensitive, most power-hungry headphones on the market, even speakers of low sensitivity can be
The headphone output is 20w, pure Class A. The amplifier output is 50w, pure Class A and 110w, Class A/B. The SRPP circuit uses six 6922 vacuum tubes and six pairs of transmitters in parallel along with a separate power supply design.
The EF1000 volume control uses the same relay-based attenuator technology from the SHANGRI-LA. This offers a silky smooth response and ultra-low distortion from its use of dedicated pathways.
