• Power supply voltage 30V
• Dual power supply LDO for cleaner power
• Newly equipped with power control circuit
• Converts balanced input and outputs high-power SE Advantage 1: Extended battery life and reduced heat generation Advantage 2: Further clarified sound image and positioning Advantage 3: Reduced white noise from DAP

※Uses 6 black batteries

SOUND TIGER E-CM (Enthusiast Classic Monitor) Release December 2025

The best SOUND TIGER ever has been completed in terms of power, clarity, positioning, sound image, tonal balance, and musicality. This is a true all-genre amplifier. There are no more words to describe the sound quality. Please listen and confirm its true value. Fujitsu black batteries recommended: Approx. 9.5 hours duration (30V mode) A headphone amplifier with 4.4mm balanced input and 4.4mm single-ended output.

Basic Specifications

• A headphone amplifier with 4.4mm balanced input and 4.4mm single-ended output.

• Optimal for DAPs with balanced output.

• No volume control implemented to avoid sound quality degradation.

• Operates with AA nickel-metal hydride or alkaline dry batteries.

• Shows its full potential after 50 hours of aging, 20 minutes after power-on.

  Power	Maximum 1700mW @33Ω (single channel drive) ※
  Frequency Response	5Hz～4MHz -3dB
  Distortion	0.0017% 30kHz LPF (best value)
  Output Impedance	0.25Ω
  Amplifier Gain	2.56x
  Gain SW
  Input Attenuator	ON: 0dB
  OFF: -6dB
  Operating Temperature	0 °C to +40 °C (Non-condensing) ※2

※The production version has a power supply current limit, so the output is 1700mW. With the current limit disabled on the prototype, we measured 1940mW. ※2 Please exercise caution when using outdoors on days of extreme heat.

Difference between Balanced-SE Conversion and Full Balanced Circuits

Balanced-SE Conversion

Full Balanced

New Feature: Power Control

When you turn the power switch ON, the white LED lights up, which is the same as conventional models. Additional Feature When less than 1 hour remains, the white LED starts blinking. This is the appropriate time to replace the batteries. (Since the remaining capacity is below 10%, it does not cause memory effect) When 0% remaining capacity is determined, the LED switches to red and the amplifier power turns OFF. Until the batteries are replaced, the system remembers the white LED blinking stage and the red LED stage. When batteries are replaced, the memory is reset, and the white LED lighting and amplifier power are restored.

Also, a semiconductor fuse is installed to prevent damage to the amplifier circuit in case of an accident.
