Rock your cans. The VHP•2 improves over our VHP•1 with a new potentiometer, 2 oz. copper circuit board, silver solder construction and select upgraded internal components.

Owners Manual



New and Improved

Our new VHP•2 is an improved version of our highly acclaimed VHP•1. Improvements include a new ALPS® Blue Velvet potentiometer, 2 oz. copper circuit board with silver solder construction, and a handful of upgraded internal components. As before, it is a versatile studio quality headphone amplifier for use with most any headphones.

Audio Circuit

Unlike most amplifiers, it uses a unique current-feedback circuit rather than opamps, and is optimized for a wide range of load impedances (30-700 ohms). This high bandwidth, extremely low noise design yields greater than 120 dB of dynamic range and exceeds the capabilities of the human ear, ensuring that nothing audible is lost due to the amplifier.

Current-on-demand at the output, enables the amplifier to respond quickly and linearly when necessary without risk of output distortion. When large amounts of output power are suddenly needed, the amplifier can respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise performance, and the high slew rate prevents odd order distortion.

Headphone Swiss Army Knife

Two gain settings, selectable by a convenient front panel switch, allow for quick and easy optimization for high or low efficiency headphones. Other features include Short Circuit and Thermal protection, looped-through output jacks and external 14vAC power supply.

Tone Audio LogoSide by side with the VHP-1, the new model is definitely a step up. The thing we both noticed right away was the improved soundstaging of the new unit. Steve said ‘What a difference! More dynamics, better sound- staging and an even quieter background make this one a real treat for serious headphone users…’”

Stereophile LogoThe Channel Islands Audio VHP•1 is a heck of a good headphone amplifier. It’s versatile and it’s tiny, which means you can pretty much put it where you need it. It’s also convenient, possessing an impedance switch and a unity-gain feed-through, both thoughtful features. By itself, it would have made my short list of must-audition headphone amps.

Add the VAC•1, however, and the VHP•1 rockets to the top of that short list. The increases in bottom-end extension and power—and, more important, dynamic contrast—make it a serious rival for the best of class in its price range—and maybe way above it.”
