A revolutionary analogue headphone amplifier. Your headphones will sound like never before. Passionately designed balanced amp with latest 4.4mm Pentaconn connectors for input & 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 & vanishingly low distortion.
