Yamamoto Sound Craft HA-02

The Yamamoto Sound Craft HA-02 headphone amplifier is a real thing of beauty crafted from Cherry wood. Mr. Yamamoto is a perfectionist and each item is carefully crafted before it is shipped to the owner or it is not shipped at all until everything is perfect. "Perfect" is exactly how I would describe the appearance of the HA-02. This beauty will set you back 88,000 Yen (excluding postage), that's about US$958.00 at time of writing.
