V-Moda Release VAMP – Audiophile Battery Pack For iPhone 4/4S
V-Moda, the maker of the Crossfade M-80, has announced VAMP, a headphone amplifier that combines a dedicated 150mW x 2 Hi-FI amplifier, Digital-to-Analog convertor (DAC), optical audio output and 2200mAh battery all integrated into a solid metal casing for the iPhone 4/4S.

VAMP’s high fidelity DAC processor extracts the digital signal of the iPhone to bypass the iPhone’s internal DAC to deliver a claimed better audio experience. V-Moda claims VAMP’s 150mW x 2 amplifier is five times more powerful than the iPhone’s amplifier and provides up to 8 hours of playback. VAMP’s rotary volume knob allows you to finely adjust the volume and its hi/lo gain switch adjusts the output level.

The PURE mode processes audio in the truest of forms while the VQ (V-MODA eQualizer) mode adds a slight spatial 3D soundstage, tightened bass and increased treble attack that invigorates an all-around sensory experience.

The AMP/DAC is integrated into a sleek, aircraft-grade brushed metal that is designed to pay homage to the grooves in a vinyl record. The shock absorbing silicone protects your iPhone and allows for quick removal. The 2200 mAh lithium-ion battery can be used as a backup power source for the iPhone 4/4S, virtually doubling its battery life. Another unique feature is an Optical audio output that allows you to connect VAMP to your A/V receiver or DJ mixer via Toslink or SPDIF optical audio, transforming the iPhone into a Hi-Fi grade audio source that can be used a lifetime after the phone function is retired.
VAMP offers two, selectable, audio modes:
» PURE mode (indicated by the red light on the LED toggle switch) outputs audio in its original form
» VQ mode (indicated by the green light on the LED toggle switch) adds a slight spatial 3D soundstage, tightened bass and increased treble attack that invigorates an all around sensory experience
