Maintained! A heavyweight high performance premain amplifier that is above its class. The sound quality is tight throughout the entire range, but the characters are neutral without getting too stiff. This is truly a high cost performance model from Sony's golden age. PHONO is also MM/MC compatible, making it great for analog users. On the exterior, there are bumps, threads, and peeling and chips on the side panels. Serial 204636 (Yonejima Satoshi)
