A revolutionary analogue headphone amplifier. Your headphones will sound like never before. Passionately designed balanced amp with latest 4.4mm Pentaconn connectors for input and output. Each Panasonic ECPU capacitor features some 3500 layers of ultra-thin dielectrics less than 0.5μm thickness. This gives class-leading Equivalent Series Resistance (ESR) low impedance (other than at thedesired capacitance) as well as frequency stability and vanishingly low distortion.
