Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•The N7 is a compact class-A fully-discrete headphone amplifier, featuring twin JFET (junction field-effect transistor) input, R2R electronic volume control, dual-level Class A current adjustment, dual gain settings, and an independent Class-A preamp function. This high-performance headphone amplifier delivers rich, high-fidelity sound with exceptional musicality
•[Twin JFET, Tube-Like Sound] JFET has high input impedance and a smooth, tube-like sound signature. The N7 utilized not just JFETs. It’s a pair of matched twin JFETs packaged together—ensuring consistent temperature rise and stable midpoint voltage, making it the ideal input stage for amplifiers
•[Class-A Dual-Level Adjustable Current] Features a specially designed dual-level Class-A bias current adjustment for the output stage, keeping the amplifier’s outputs in true Class-A operation. Class-A amplification delivers silky-smooth, full-bodied audio with naturally warm and lush tonality
•Better UI, Better Experience] The Class-A amplifier's transistors operate continuously in their linear zone, generating consistent heat. Our structural engineer designed a 3D thermal architecture—from planar to spatial heat dissipation—ensuring the N7 maintains balanced Class-A operation for stable, uncompromised sound.
•New UI, intuitive controls. Two colors to present the real-time current level and temperature. Clear at a glance
•[Outstanding Specifications, The Foundation of Great Sound
•Professional Tuning, Natural and Musical] Headphone output noise floor (high gain): 3μV; THD+N: 0.0004%. Outstanding hardware performance lays a solid foundation for exceptional sound.
•The tuning is natural and musically engaging, calibrated on-site with reference-grade equipment to faithfully reproduce every nuance — guided by the authentic character of real instruments and a deep understanding of musical expression
