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)

This headphone amp simply sings! This ABYSS Edition amplifier was designed using ABYSS Diana series headphones and provides a beautiful sonic mate to complete your high-end headphone system.

Claire ★★★★★

The

Henry I. ★★★★★

The background is dead silent even with sensitive IEMs, which I didn't expect from a class A amp. Balanced output through my planar cans sounds noticeably wider than my old single-ended setup.

Stella O. ★★★★★

Paired this with my planar headphones and the class A warmth is immediately noticeable—vocals feel smoother without losing any detail. The fully balanced design keeps everything dead silent even at higher volumes, which I wasn't expecting at this price.
