Eleven Audio Broadway Balanced Headphone Amplifier 2025 Edition






Category: Electronics
Description
The world's first high performance full balanced discrete class A headphone amplifier by Eleven Audio TM combines smooth detailed sound with the noise free black backgrounds. Amazing low level detail, smooth very real mids and 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. Circuitry is designed to float the batteries on the mains at all times for pure clean sound.
Accepts only balanced XLR L/R channel inputs. Four channels of amplification straight through to a high performance balanced headphone connection with 1.5 full watts of super smooth sounding class A bias amplification. DC coupled means huge low frequency bass resolution, the Broadway sounds way larger than it looks and can drive more power hungry headphones with ease. (For very demanding headphones see Eleven Audio Formula S Amplifier)
