XI Audio, or Eleven Audio, is a relatively young Taiwanese brand that makes primarily headphone amplifiers and DACs. The company is run by a familiar face of our scene, namely Michael Xiao, who has been heavily involved with Lotoo before he started his own journey.
XI Audio’s product range might be small, but they definitely produce statement and outside the box products. The team around Michael Xiao introduced themselves with the Formula S amplifier, which was made specifically as the best pairing for the Abyss AB-1266 headphones. A headphone I rate very highly for its sound. Sadly I don’t have it anymore to play around, but the Diana range of headphones is with me and we will take a look later how the XI Audio x Abyss system performs.
Apart from the Formula S amplifier, XI Audio offers a resistor ladder R2R DAC with their SagraDAC, but also battery powered transportable desktop amplifiers. Which we will look at today.
