For sale: the legendary Sennheiser Orpheus system, comprising the HEV 90 headphone amplifier and HE-90 headphones.

This system is in excellent condition and functions perfectly. Cosmetically, only minor signs of wear are present, primarily on the highly sensitive chrome surface of the HEV 90—an unavoidable characteristic over time.
Both devices have been fully tested and serviced by the official Sennheiser Orpheus service. The HE-90 headphones have been fitted with new earpads and a new headband, while the HEV 90 has been thoroughly inspected, revised, and recalibrated.
This particular set is from the later production run of the highly limited 300-piece series. It features the improved HEV 90 tube amplifier, incorporating the latest optimizations made during production. Additionally, this HEV 90 model includes a Stax Pro terminal, allowing compatibility with Stax headphone models.
