Eleven Audio XI Audio Fully Balanced Headphone Amplifier in excellent, like-new condition with brand new batteries. I’m the original owner and purchased these from an authorized dealer in December 2020. A perfect mate for the Abyss Diana Phi headphones and recommended by Abyss as the perfect pairing for the Diana Phi.

I've been a head-fi member for a while, but I have only sold here once before. I have 100% positive feedback on Audiogon (username = lmpine) dating back to 2004.

Price includes shipping to ConUS, PP G&S add 3.5%.
