Designed for the discerning listener, the Bravo V3 Headphone Amplifier delivers high-quality tube amplification with impressive sound control. For amplification, it features an Electro Harmonix 6922 12AU7-style tube that produces a warm sound signature to brightens up music without blowing it out. When paired with a "darker" set of headphones, this tube makes for a rich listening experience. It can also be switched out for a different tube and a new sound flavor. Want to shape your sound without extra hardware? The V3 comes equipped with three-band equalization knobs, so you can tweak the bass, mids, and treble of your output. Its open-air design not only looks new unique—it also lets in more airflow and for optimal cooling. The V3 supports output impedances between 20 and 600 Ohms to handle any pair of headphones. Accepting both RCA and 1/8-inch inputs, this compact amp pairs well with a DAC and works great by itself.
