The Broadway is a sophisticated headphone amplifier designed with absolute sound quality in mind. It’s the world’s first high performance fully balanced discrete Class A headphone amplifier and combines smooth detailed sound with the noise free uber-quiet backgrounds. Amazing low-level detail, a smooth realistic midrange with natural sounding vocals and clear highs only begin to describe how good this amp is!

Internal user replaceable batteries dramatically reduce AC line noise to negligible levels. This amp will run for hours without AC power, or plug in for continuous play, with the same highly refined sound on either power source. The advanced circuitry is designed to float the batteries on the mains at all times for pure clean sound.

The Broadway accepts only balanced XLR L/R channel inputs. Four channels of amplification straight through to a high performance balanced headphone connection with 1.5 Watts of super smooth sounding class A bias amplification. DC coupled means huge low frequency bass resolution, the Broadway has a big expansive sound and can drive nearly any power hungry headphone with ease.

Class A designs are known for their immediacy & natural sound. The Broadway takes those attributes and presents them with a dose of effortless finesse. Extraordinary!
