Audio-Technica AT-PHA100 Headphone Amp

You don't have to settle for wimpy, muddy sound just because you're on the go. The AT-PHA100 Portable Headphone Amplifier is small (width and length comparable to a smartphone) but packs a powerful punch. Engineered using select audio components, and enclosed in all-aluminum casing to protect the circuitry, the AT-PHA100 gives headphones a rich, detailed boost throughout the sonic range with ultra-low distortion.

The AT-PHA100 is equipped with both analog and digital inputs (3.5 mm jack and USB micro-B, respectively) and 3.5 mm headphone jack. It also features a high/low gain switch, machined aluminum volume knob, and five-stage sampling indicator for digital input. The internal lithium polymer rechargeable battery lasts up to 14 hours when amplifying an analog signal, and up to 6 hours when amplifying a digital signal.

The amplifier comes with two rubber bands and a rubber mat for strapping the unit to a smartphone or other portable device, a 1.0 m USB cable (USB 2.0 to USB micro-B) and a 10 cm audio cable terminating in a 3.5 mm gold-plated stereo mini plug at each end.

Features:

- Specially selected, discrete circuitry enhances the resolution throughout the frequency range
- NJR MUSES 8832 pre-amp delivers rich, powerful sound from low to high frequencies
- DAC ESS ES9018K2M circuit samples 384kHz/32-bit PCM, and DSD audio sources at 2.8/5.6MHz
- Texas Instruments LME49720 op-amp suppresses distortion for crystal clear mid to high frequencies
- Internal rechargeable lithium polymer battery lasts up to 14 hours
- High/low gain switch and machined aluminum volume knob
- Five-stage sampling indicator (for digital signal input)
- All-aluminum enclosure protects delicate circuitry
- Includes two rubber bands and a rubber mat for strapping amp to a portable device, a 1.0 m USB cable (USB 2.0 to USB micro-B) and a 10 cm audio cable with 3.5 mm mini plugs

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
