V-MODA has introduced an accessory for the modern audio connoisseur with VAMP, a precision headphone amplifier that combines a dedicated 150mW x 2 Hi-FI amplifier, DAC (Digital-to-Analog convertor), optical audio output and 2200mAh battery all integrated into a solid metal casing for the iPhone 4/4S.

VAMP’s audiophile-grade, high fidelity DAC processor extracts the digital signal of the iPhone to bypass the iPhone’s internal DAC. VAMP’s 150mW x 2 amplifier is five times more powerful than the iPhone’s amplifier and provides up to eight hours of playback, says Val Kolton, chief visionary officer and founder of V-MODA. VAMP’s rotary volume knob allows you to finely adjust the volume and its hi/lo gain switch adjusts the output level, he adds.

The VAMP features two new audio processing modes for the most discerning audiophile, according to Kolton. 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, he adds.

The AMP/DAC is seamlessly integrated into a sleek, aircraft-grade brushed metal 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.

Another 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. VAMP is available immediately at V-MODA.com/VAMP and Amazon.com for US$650
