Up for sale is a Pass Labs HPA-1 headphone amplifier in excellent condition. It is in the conversation for the best headphone amp available at any price. Don't take my word for it though:
"As balanced headphone operation is the audio fashion du jour, it might be felt that Pass Labs's sticking with single-ended operation could work against the HPA-1. But regardless of circuit topology and the active devices, it's the sound quality that matters, and on that count the HPA-1 scores big-time. Yes, it's an expensive headphone amplifier; but I venture to suggest that, in bass clarity and authority and in midrange transparency, the Pass Labs HPA-1 is without peer."
