LUXURY&PRECISION EA4 

  • Finely tuned tube preamp circuit powered by high voltage at the tube anode ILA/ILH dual modes paired with high and low gain for the tube provides four tube sound styles.
  • Precision constant current source with discrete components
  • Equipped with 12 Panasonic film capacitors for tube preamplifier coupling
  • Specially selected linear regulators optimized for the tube's resonance frequency
  • CNC machined metal double tube shield and protective cover
  • Vibration-damping tube design: 8 high-damping silicone buffers on both sides
  • Two independent high-performance plus and minus power supplies
  • 16 Nichicon 10x12.5 mm audio-grade aluminum electrolytic capacitors for power supply filtering in the discrete headphone amplifier
  • Selectable ±13V and ±15V voltage levels for the headphone amplifier
  • Six Panasonic 18650 battery cells with low internal resistance
  • The internal resistance between the cells is less than 0.5 milliohms
  • Discrete headphone amplifier circuit uses 8 power transistors in TO252 package 
  • Discrete large transistor emitters use 24 pieces of 250mW 0.5%
  • Precision resistors with low temperature drift
  • AB-to-A headphone amplifier mode with 11 adjustable static current levels
  • Double click the power button to switch between pure tube preamp mode and tube preamp + discrete headphone amp mode with potentiometer like the LP6 7th Anniversary Edition, with visual volume design
  • Symmetrical output power per channel: 6500mW @32N, 1200mW @ 300
