Released in 1996, creek OBH-11 ¥40,000 Made in the UK Accessories: Genuine AC adapter This is not the re-release model from around 2012, but the initial production model. The early model features the classic green logo and uses high-precision parts for the volume control, allowing for precise click adjustments. Operation has been confirmed. Sound output from RCA input, parallel output, and headphone jack is normal. No volume pot noise. The exterior has no major issues, but there is a touch-up mark of about 1mm on the upper right corner of the front panel, which is barely noticeable. See the photos. Recommended impedance: 30-300Ω At the time, this headphone amplifier was designed for popular overseas headphones like the Sennheiser HD580 (300Ω) and AKG K500 (120Ω), and can drive up to 300Ω. With AKG K701 and 501, sufficient volume was achieved at around the 10 o'clock position, so the driving output is more robust than recent models. The sound has a solid thickness and richness without sounding thin. Free shipping, final price. At the time, buying the AC adapter separately cost ¥5,000, so this is a great deal. Please do not use any AC adapter other than the genuine one, as the OBH series has a unique rated output and is designed for Japanese specifications. Shipped via Yu-Pack Mercari service.
