The VP-V1 from Fostex is a high performance portable vacuum-tube headphone amplifier, which amplifies the sound of line-level playback equipment, such as a portable audio player, and outputs through a dedicated headphone jack. The vacuum tube on the primary stage, coupled with the custom Fostex capacitor delivers a rich textured sound from any audio source. A Hi/Lo gain switch is provided to drive a broad selection of headphones, while the built-in Lithium-ion battery charges in 3.5 hours and provides up to 10 hours of continuous playback. The HP-V1 ships with a 3.9" / 100mm cable with 1/8" / 3.5 connectors and an AC power adapter.
