Audio Technica AT-BHA100 Balanced Headphone Amplifier

AT-BHA100 The AT-BHA100 balanced headphone amplifier is designed to deliver unmatched audio quality from high-resolution sound sources, and is ideal for use with hi-fi headphones such as the ATH-ADX5000, ATH-MSR7b, and those in the ATH-AW Series. This compact desktop unit is compatible with Direct Stream Digital (DSD) and other high-definition formats to reproduce every detail of the original recording. The AT-BHA100 features a hybrid system of vacuum tubes and power transistors to enhance the beauty and warmth of amplified sound. It employs four completely independent amplifier circuits, a high-quality New Japan Radio MUSES8820 operational amplifier, and specially designed low-noise relay switches to emphasize the depth and warmth of vacuum-tube sound. A four-layer board structure with high-quality audio-grade components from Nichicon, WIMA, and Shinyei Capacitor ensures rich, natural audio. The amplifier is equipped with a 4.4 mm TRRS jack and a 4-pin XLR terminal, plus a low/high gain selector switch, allowing it to accommodate a wide range of balanced headphones with varying sensitivities and impedances. It also has two 6.3 mm (1/4″) outputs with independent volume controls that can be used simultaneously for comparative listening.   Hybrid system with vacuum tubes and power transistors enhances the beauty and warmth of amplified sound Four independent JJ Electronic ECC83S preamp vacuum tubes deliver superb depth and sense of presence in the amplified sound Four power transistors (one for each powered amp circuit) are capable of high-power performance to handle the wide dynamic range of sound sources with high sampling rates Completely independent four-circuit structure, with separate left/right amplifier circuits and balanced hot/cold circuits, helps suppress crosstalk for a rich sound field High-quality New Japan Radio MUSES8820 operational amplifier highlights the depth and warmth of the vacuum-tube sound Specially designed low-noise relay switches offer excellent dynamics that emphasize the spaciousness and vibrancy of the sound Nichicon chemical capacitors contribute to the low-frequency characteristics of the audio, leading to powerful bass WIMA and Shinyei Capacitor film capacitors create smooth, low-distortion sonic characteristics for natural, clear sound Four-layer board structure, with independent layers for signal circuits, power circuits, and ground circuits, ensures greater signal stability for rich, low-frequency control Low/high gain switch offers support for a wide range of headphones with varying sensitivities and impedances Two balanced outputs – 4.4 mm TRRS jack and 4-pin XLR terminal – are compatible with a wide range of balanced headphones Two 6.3 mm (1/4″) outputs can be used simultaneously with independent volume controls RCA line-through output allows for switching between headphones and powered speakers All sides of the amplifier are vented for improved dissipation of heat and a superior signal-to-noise ratio through reduced thermal noise Compact unit can be set up vertically or horizontally Large-capacity external AC adapter separates the power supply from the main unit for reduced noise
