Works Well
I just moved to France and am setting up my sound system. I purchased this and Stax Lambda headphones for my new home audio system, and it works well and looks good. I can not compare it with the other electrostatic headphone amplifiers available for Stax headphones because I have not heard any of those available now, but this is a fraction of the cost and sounds clear and clean to me. I like the visual aesthetic (and the fake tube glow, which amuses me, but...I like it), and I am contented with this product's ability to drive my difficult-to-drive headphones.
