Description

L&P EA4 Flagship Portable High-Power Tube Amp

Maximizing Tube Sound part 1

Optimized Tube Preamp Circuit: The voltage amplification is solely handled by the tube preamp, with the anode supplied by high voltage. This design fully releases the special tone of the tubes, delivering a rich and warm tube sound. The fully discrete power amp is designed purely for power output, focusing on current amplification.

Maximizing Tube Sound part 2

The combination of ILA mode and high gain allows for additional tube amplification gain, enhancing the already rich tube sound. To actively attenuate the gain of the headphone amplifier’s input stage, rather than through simple resistive voltage division, preserving more musical details. Twelve Panasonic film capacitors are used for coupling in the tube preamp stage

Combination of multiple Tube-Tone


The ILA and ILH modes, combined
with the high and low gain settings for
the tube, offer 4 rich and sweet sound
style, unlocking various listening
experiences.

Comprehensive Reduce the Microphone Effect


A precision CNC-machined metal shield for dual tubes.
Eight high-damping silicone pads on both sides.

Resolving the Performance and
Longevity’s core problem from the “Battery core”


Panasonic Original Low-Resistance, High-Reliability Cells. Carefully Matched Cells for Voltage and Internal
Resistance. Each Cell in the Battery Pack Has an Internal Resistance Difference of Less Than 0.5 Milliohms.

An Interesting and Useful Tube Preamp /Headphone Amplifier Switching Function

Double tap the power button to switch between pure tube preamp mode / tube preamp +discrete headphone amp mode. Prevent accidental touches and sudden high volume that can occur with toggle switches or single press buttons. Maximizes the benefits of the tube preamp circuit and mechanical design.

A combination of Technology and Art in Volume Control Design

The potentiometer as same grade in the LP6 7th Anniversary Edition. The volume knob features added scale markings, making the potentiometer volume visible. Say goodbye to sudden loudness-enjoy precise and fine adjustments!

11-Level Adjustable Quiescent Current Design for Headphone Amp for Fine-tuning Sound Quality

AB class operation with a minimum quiescent current of around 10mA.A class operation with a maximum quiescent current of up to 50mA. Custom knob with smooth, tactile clicks allows you to easily adjust for different listening experiences.
