Satri Circuit Laboratory VHA-5240C Headphone Amplifier

The VHA-5240C is a headphone amplifier that focuses solely on music listening, adapted from the VHA-5240 series originally developed for VR goggles.

The VHA-5240 series was developed to minimize time lag and accurately reproduce the surround sound used in VR, delivering high performance even for music playback. The case is made from a conductive carbon-blended filament to prevent induced noise. Compact and lightweight, it is a headphone/headset amplifier that can be easily carried in a bag or pocket.

It can be connected to headphone output terminals on smartphones or tablets, as well as line outputs on CD players or video players.

Realistic sound without distortion

The VHA-5240C precisely controls bias current to maximize information and improve accuracy. By expanding bandwidth and using a non-feedback circuit without negative feedback, transient distortions like TIM distortion are eliminated, minimizing time delay and phase distortion, allowing accurate stereo sound localization.

Overwhelming speed and freshness brought by SATRI circuitry

• "The sound rises very quickly, bringing music to life."
  The unique advantages of current transmission inherent to the SATRI circuit are fully demonstrated, making the transients feel incredibly fast. There is absolutely no delay or muddiness in the sound, and the lifelike presence of a live performance emerges effortlessly, leaving a very strong impression.
  
• "The resolution across the entire frequency range improves dramatically, and the details stand out."
  Because signal degradation is extremely minimal, it captures even the finest nuances and sense of air with precision. Details that could not be heard before naturally come to the forefront, and the texture of the sound source itself is conveyed more deeply.
  

High transparency and precise imaging

• "The background noise is minimized to the extreme, and the transparency of the sound stands out."
  With a very low noise floor, the deeper the silence in the background, the purer the sound feels. The sensation of sound emerging from stillness is a distinct charm unique to the SATRI circuit.
  
• "The sound image is positioned astonishingly sharply, and the sense of three-dimensionality is extraordinary."
  The excellent phase characteristics stand out, giving the contours of the sound image remarkable clarity. Even when listening through headphones or earphones, a deep sense of depth and spatial spread emerges, allowing the positions of instruments and vocals to be perceived with astonishing accuracy.
  

Musicality and suitability

• "The tone is free of coloration, allowing connected devices to reveal their true characteristics."
  The VHA-5240C itself has highly neutral characteristics, so it brings out the natural qualities of DACs and headphones/earphones as they are. Its pure playback without any sense of coloring is very appealing.
