Fantastic. I was surprised and delighted to find that this outperformed my fully-balanced Focal Arche in my primary system. That prompted me to also buy the Conductor 3X Reference to replace the Arche. With the C3XP, the 6.3mm jack is slightly off-center. That initially had me a little concerned about a possible build quality issue, but the rest of the build and the performance has been flawless so far. Very happy with this wonderful DAC/amp.
