For sale is a used but in mint condition XI Audio Broadway amplifier. 

The world's first high performance full balanced Li Ion battery discrete class A headphone amplifier by Eleven Audio TM combines smooth detailed sound lacking any power supply noise or AC line interaction. Amazing low level detail, smooth very real mids and vocals, and clear highs just begin to describe how good this amp is!

The Broadway is XI Audio’s higher powered amplifier of the Broadway range. It delivers 1.5W into 32 Ohms, which might not be as high as what other amps offer, but it’s still enough to get the HiFiMAN Susvara to blasting volumes.

It uses a set of four Li-Ion batteries, which gives the Broadway a run-time of approximately six hours. The design of the amplifier allows for it to be used while charging. It will use battery power until it reaches a certain power-level before the Broadway starts charging them again. So you will run on clean power for the majority of time when you have it connected to the power outlet of your house.

The Broadway is a fully balanced, discrete, Class A headphone amplifier. There is no single ended RCA input on it. So you have to use XLR at all times, as it is meant to be used fully balanced. Its rated Signal to Noise Ratio is 130dB.

On the front you have a 4-Pin XLR and a 4.4mm Pentaconn output for your headphones. On the right hand side the volume potentiometer is seated. Unlike any other amplifier I’ve laid my eyes on, this one starts at 11 o’clock. Which of course is a hint at their brand name. The Broadway has an output impedance of below 0.1 ohms. The Broadway has two gain stages – high and low.
