Loxjie P20 Full Balance Tube Headphone Power Amplifier

Loxjie P20 Full Balance Tube Headphone Power Amplifier

Introduction

P20 is Loxjie's first full balance tube amplifier.

It use the military grade 6N3 tube,Plus the well-designed and calibrated amplifier circuit! Let the amplifier have lower distortion under the premise of ensuring"Tube Style"! And the P20 also has true balanced inputs and outputs!This can maximize the performance of the headphones!
 

Characteristic
