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
