Topping NX7 Portable Headphone Amplifier

Topping has a rich history of audiophile products that breathe new life into any piece of gear— and the NX7 Portable Headphone Amplifier is designed to bring the best out of even the most power-hungry headphones. Sporting output power that climbs up to 1200 milliwatts at the lowest ohm ratings—but an impressive 90 milliwatts even at 600 ohms—the NX7 can drive virtually any pair of high- or low-impedance headphones. To go with that power, the NX7 also delivers a impressively low total harmonic distortion with a signal-to-noise ratio up to 135 decibels, and an equally impressive dynamic range. There are two outputs—4.4- and 3.5-millimeter—to suit a wide variety of cables, and thanks to wide frequency spectrum coverage, this little amp casts a wide net in audio response. All of that sonic prowess sits in a portable package complete with NFCA architecture, a 20-hour battery life, and just around five by two-and-a-half inches of real estate—so you can pop it into your pocket and you'll be ready whenever you need to fire it up.
