Rarely seen in the second hand market, the Auralic Gemini 1000 (RRP US$1199) is a superb DAC/headamp that also has included a $400 headphone stand. It will enable you to drive any headphones of your choice from the convenience of a headphone stand! It has driven my Focal Utopia and Hifiman HE-1000 brilliantly.
The Gemini 1000 has been compared favourably to the Auralic Vega / Taurus stack, and also to the Chord Hugo. It also has a favourable review from Srdjan at 6moons.

The Gemini 1000 version gives up very little to the Gemini 2000, which makes the Gemini1000 a real bargain.
