aune N7 Class-A Headphone Amp, Pre-amp, Pure Class-A Fully-Discrete Fully Balanced, 6.35mm/4.4mm Headphone Jack, Twin JFET, XLR/RCA Preamp Out, for DAC/Active Speaker/Home Audio

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. Its a pair of matched twin JFETs packaged togetherensuring 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 amplifiers outputs in true Class-A operation.

Class-A amplification delivers silky-smooth, full-bodied audio with naturally warm and lush tonality ^^ [Full Aluminum Chassis & Stable Class-A Thermal Performance ^^ 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 architecturefrom planar to spatial heat dissipationensuring 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
