Condition: 8.5/10. Item is in excellent condition. Comes with the upgraded PSU1 power supply. Both the amplifier and power supply comes in original packaging and boxes.
Sounds lifelike, dynamic, great timing and solid bass. Highs are super refined and vocals are super smooth.

A best selling headphone amplifier that takes all the good points of valves/tubes, but wont wear out like valves/tubes and drives low impedance headphones too!
