The Broadway S is a Single-Ended Class A headphone amplifier designed with absolute sound quality in mind. Designed for low impedance or higher sensitivity headphones, it produces amazing low-level detail, a smooth realistic mid-range with pristine vocals and crystal clear yet non-fatiguing highs.

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 circuitry is designed to float the batteries on the mains at all times for pure clean sound.

Lucky owners have commented that the Broadway S sounds way larger than it looks due to its extended effortless sound. It delivers up to 800mW of super smooth sounding class A bias amplification and being DC coupled, it has huge low frequency bass resolution. It is an ultra-low noise design with 2 gain settings and is capable of transporting you into the music with its energy and realism.

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